1 00:00:06,530 --> 00:00:13,790 And now what we can do is we can go ahead and modify our IP service to account for this one as well. 2 00:00:13,980 --> 00:00:20,310 So go ahead and head into IAP service and this is where we need to modify because right now we're only 3 00:00:20,310 --> 00:00:24,090 passing in one one set. 4 00:00:24,150 --> 00:00:25,700 Right one IAP. 5 00:00:25,800 --> 00:00:29,720 Now what we're going to do is we're going to go ahead and actually create an array and then we're going 6 00:00:29,710 --> 00:00:31,970 to for loop through them and insert them one by one. 7 00:00:31,980 --> 00:00:39,600 So go ahead and type let product IDs equals an array containing IAP. 8 00:00:39,650 --> 00:00:42,330 Neil ID as well as IAP. 9 00:00:42,360 --> 00:00:44,900 Hide ads Id get rid of that. 10 00:00:44,910 --> 00:00:53,150 And now what we can do is we can say for ID in product IDs we can go ahead and call product IDs insert 11 00:00:53,220 --> 00:00:55,480 and we can insert the ID. 12 00:00:55,680 --> 00:01:00,190 So by the end we have a set with two items one is IAP Mileti. 13 00:01:00,210 --> 00:01:02,280 The other one is hide adds ID. 14 00:01:02,550 --> 00:01:04,090 OK super simple. 15 00:01:04,320 --> 00:01:08,640 Not too bad although look at that its giving us some trouble. 16 00:01:08,800 --> 00:01:14,410 Its saying cannot use on non mutable to let constant What are you talking about. 17 00:01:15,280 --> 00:01:16,760 Product IDs is a very. 18 00:01:16,960 --> 00:01:17,720 Oh this one. 19 00:01:17,820 --> 00:01:18,050 OK. 20 00:01:18,070 --> 00:01:26,170 So let's just let's change this to just be IDs then and just say for ID in IDs that way we're actually 21 00:01:26,170 --> 00:01:28,790 referring to the proper set. 22 00:01:28,790 --> 00:01:29,840 Very cool. 23 00:01:29,950 --> 00:01:34,540 So now when we load our app we have access to hide ads ID. 24 00:01:34,610 --> 00:01:35,860 OK super cool. 25 00:01:36,180 --> 00:01:38,620 And thanks to what we've already done. 26 00:01:38,620 --> 00:01:46,420 Believe it or not we can call our purchase function attempt to purchase for item with we can pass in 27 00:01:46,420 --> 00:01:51,340 the Product ID and we can attempt to make that purchase which is really cool. 28 00:01:51,370 --> 00:01:53,290 Let's go ahead and let's try that. 29 00:01:53,290 --> 00:02:02,160 So on detail we see when the hied ads button is pressed we just need to call IAP service instance attempt 30 00:02:02,270 --> 00:02:07,470 to purchase for item with product index hide ads and that's what we're going to pass in. 31 00:02:07,600 --> 00:02:12,880 So that way we can attempt to purchase for hiding ads and I don't know about you but I really want to 32 00:02:12,880 --> 00:02:13,740 see if it works. 33 00:02:13,810 --> 00:02:20,840 Let's go ahead and build and run let's test to see if we can successfully queue our hiding ads in at 34 00:02:20,850 --> 00:02:21,740 purchase. 35 00:02:21,880 --> 00:02:23,390 Let's give it a test here we go. 36 00:02:23,680 --> 00:02:30,830 So pull open the simulator here and let's go ahead and select an item tap hide ads for 99 cents. 37 00:02:30,880 --> 00:02:32,480 OK it's going to ask us to sign in. 38 00:02:32,590 --> 00:02:34,180 Fine. 39 00:02:34,210 --> 00:02:36,040 Test test one two three. 40 00:02:36,370 --> 00:02:38,060 Whoops only one exclamation mark. 41 00:02:38,060 --> 00:02:41,890 Press OK and we should get a Q here. 42 00:02:41,890 --> 00:02:44,470 Do you want to buy one meal for 999. 43 00:02:44,890 --> 00:02:48,100 That's not the right purchase press cancel. 44 00:02:48,100 --> 00:02:53,700 Now watch what happens when I tap by this item it says Do you want to buy one hide ads for 99 cents. 45 00:02:53,710 --> 00:02:55,450 Why is it flipped. 46 00:02:55,450 --> 00:03:03,920 The reason for that is because we set a specific product ID K meal being 0 and hide ads being one. 47 00:03:03,970 --> 00:03:08,680 But when we create this set we pass in IDS. 48 00:03:08,740 --> 00:03:14,800 We pass in the ID then we pass in Hyde ad and it ends up being reversed. 49 00:03:14,800 --> 00:03:20,350 So what we can do is we can go ahead and just pass that one in first and then it will be properly set 50 00:03:20,350 --> 00:03:27,530 at the bottom of the set because insert basically inserts the given element at the top. 51 00:03:27,760 --> 00:03:28,250 OK. 52 00:03:28,450 --> 00:03:30,760 So when you insert a new element it puts it at the top. 53 00:03:30,760 --> 00:03:34,740 So we need to put the meal at the top and hide ads idea at the bottom. 54 00:03:34,810 --> 00:03:36,520 OK so we've got to go in reverse order. 55 00:03:36,700 --> 00:03:37,630 Let's try that again. 56 00:03:37,630 --> 00:03:43,150 We're going to build and run and we'll see if reversing that properly allows us to choose the purchase 57 00:03:43,180 --> 00:03:44,100 we want. 58 00:03:44,110 --> 00:03:45,280 Let's take a look. 59 00:03:45,310 --> 00:03:51,110 Select Top buy or hide ads for 99 cents and we get a crash. 60 00:03:51,140 --> 00:03:53,740 Interesting index out of range. 61 00:03:53,740 --> 00:03:55,320 Now why would that be. 62 00:03:55,360 --> 00:03:56,610 This is another error. 63 00:03:56,950 --> 00:03:59,620 Do you notice IAP products loaded. 64 00:03:59,620 --> 00:04:00,430 I don't. 65 00:04:00,430 --> 00:04:03,660 That's because we never loaded them than we went in too fast. 66 00:04:03,670 --> 00:04:10,690 So later on we can set up something where everything is locked until that protocol is called or I guess 67 00:04:10,690 --> 00:04:15,160 that delegate method here is called We can set it to lock everything until this is called. 68 00:04:15,190 --> 00:04:16,770 So go ahead and build and run again. 69 00:04:16,780 --> 00:04:21,210 And we're going to wait this time until our IAAPA products are loaded. 70 00:04:21,310 --> 00:04:21,760 OK. 71 00:04:21,880 --> 00:04:27,520 So now they are you can see that here now that they're loaded we can go in we can tap one and it says 72 00:04:27,520 --> 00:04:29,680 Do you want to buy one meal for 999. 73 00:04:29,680 --> 00:04:30,700 It still says that. 74 00:04:30,790 --> 00:04:38,440 Interesting and it still says Would you like to buy that item so it looks like arranging the order is 75 00:04:38,440 --> 00:04:39,860 not having an impact. 76 00:04:39,990 --> 00:04:43,150 What does have an impact though is changing the index. 77 00:04:43,150 --> 00:04:48,450 So let's go ahead change this to one to zero and I like to put this this way. 78 00:04:48,520 --> 00:04:54,080 Like so hide ads and meal and let's go read up a little more on why this is happening. 79 00:04:54,190 --> 00:04:56,130 Inserts the given element into the set. 80 00:04:56,140 --> 00:05:00,820 If it's not already present if an element equal to new member is already contained this method has no 81 00:05:00,820 --> 00:05:01,420 effect. 82 00:05:01,630 --> 00:05:03,400 So it only adds new elements. 83 00:05:03,580 --> 00:05:04,150 And let's see. 84 00:05:04,150 --> 00:05:12,550 So they add in Wednesday Friday and then they insert Monday so it prints Monday because that's the new 85 00:05:12,550 --> 00:05:13,100 one. 86 00:05:13,270 --> 00:05:20,140 Then they print the whole set and it prints Friday Wednesday Monday so it looks like the last element 87 00:05:20,830 --> 00:05:22,310 gets printed first. 88 00:05:22,330 --> 00:05:26,250 The second element or the first element it's printed second and the new element goes at the very end. 89 00:05:26,260 --> 00:05:27,550 That's interesting. 90 00:05:27,550 --> 00:05:28,380 So if we insert. 91 00:05:28,390 --> 00:05:31,300 Friday it's going to go ahead and put it at the front. 92 00:05:31,300 --> 00:05:38,530 So it looks like whenever something is inserted and it's not new it goes to the front and the other 93 00:05:38,530 --> 00:05:39,220 one goes to the back. 94 00:05:39,220 --> 00:05:39,430 OK. 95 00:05:39,430 --> 00:05:39,850 Interesting. 96 00:05:39,850 --> 00:05:44,620 So it looks like this doesn't matter because these are both where we're passing them and at the same 97 00:05:44,620 --> 00:05:45,220 time. 98 00:05:45,460 --> 00:05:50,200 But it appears that they are going in this way so we're going to reverse the order of our index and 99 00:05:50,200 --> 00:05:53,440 build and run again to see if this helps our problem. 100 00:05:53,470 --> 00:06:01,950 So let's do that again pull up in our sim and let's see how we did Kate tap on salmon tap on hied ads 101 00:06:01,950 --> 00:06:03,400 for 99 cents. 102 00:06:03,420 --> 00:06:05,610 Do you want to buy hied ads for 99 cents. 103 00:06:05,610 --> 00:06:06,390 Very cool. 104 00:06:06,390 --> 00:06:09,080 Now obviously you're probably thinking this is not the most elegant way of doing it. 105 00:06:09,090 --> 00:06:09,530 You're right. 106 00:06:09,570 --> 00:06:12,060 But there are better ways of doing this. 107 00:06:12,060 --> 00:06:15,990 This is just the way that I found that worked pretty well for a simple case like this where we don't 108 00:06:15,990 --> 00:06:18,150 have a ton of complex in-app purchases. 109 00:06:18,300 --> 00:06:21,510 You would want to think of something a little more specific and less error prone. 110 00:06:21,630 --> 00:06:25,860 If you are going to be doing this for very complex apps but this will work fine just for a simple app. 111 00:06:26,100 --> 00:06:28,170 So let's see what happens when we pushed by 112 00:06:31,000 --> 00:06:32,590 your purchase was successful. 113 00:06:32,620 --> 00:06:38,500 We successfully purchased hide ads and that is a non consumable purchase so watch what happens if I 114 00:06:38,500 --> 00:06:41,980 tap it again says Do you want to buy it for 99 cents. 115 00:06:41,980 --> 00:06:43,210 Tapped by. 116 00:06:43,750 --> 00:06:45,760 And it's going to say you've already purchased this. 117 00:06:45,760 --> 00:06:47,890 Would you like to get it again for free tap. 118 00:06:47,910 --> 00:06:48,870 OK. 119 00:06:49,390 --> 00:06:50,770 Your purchase was successful. 120 00:06:50,770 --> 00:06:52,030 Very very cool. 121 00:06:52,030 --> 00:06:55,540 So that is what's going to present to you when you do that. 122 00:06:55,540 --> 00:06:59,850 If you've already bought it it knows and all it needs to do is just say hey you already got this. 123 00:06:59,850 --> 00:07:00,760 Buy it for FREE. 124 00:07:00,760 --> 00:07:01,690 Boom. 125 00:07:01,810 --> 00:07:03,020 Super awesome. 126 00:07:03,220 --> 00:07:06,620 Now we're going to do is we're going to set up something really simple. 127 00:07:06,700 --> 00:07:15,010 It's basically a way for us to determine whether the ad and the button shows or not and so to do that 128 00:07:15,100 --> 00:07:20,050 what we're going to do is we're going to use user defaults K and we're going to use user defaults to 129 00:07:20,080 --> 00:07:28,660 essentially save a Boolean for hidden or not hidden depending on whether or not the purchase has been 130 00:07:28,660 --> 00:07:30,340 made for a non consumable. 131 00:07:30,340 --> 00:07:33,160 So to do this we're going to go to IAP service. 132 00:07:33,160 --> 00:07:42,310 Scroll to the top and we're going to make a property right here called var non consumable purchase was 133 00:07:42,310 --> 00:07:48,340 made and we're going to set it to be equal to user defaults dot standard. 134 00:07:48,370 --> 00:07:52,960 OK just to access the standard user default and then call that bull for key. 135 00:07:53,020 --> 00:07:55,700 So we're making a boolean and we're saving it with a key. 136 00:07:55,720 --> 00:07:59,020 And you know what I'm going to use its name as the key. 137 00:07:59,050 --> 00:07:59,700 OK. 138 00:08:00,100 --> 00:08:06,970 And basically this key is going to be used to access this boolean value and we can save it or set it 139 00:08:08,020 --> 00:08:14,170 and then it'll save permanently into user defaults and we can use this to know whether or not a certain 140 00:08:14,230 --> 00:08:16,470 non consumable purchase has been made or not. 141 00:08:16,480 --> 00:08:16,740 OK. 142 00:08:16,750 --> 00:08:18,060 Very cool. 143 00:08:18,070 --> 00:08:24,970 So what we're going to do now is we need a way to differentiate between a purchase of a meal which is 144 00:08:24,970 --> 00:08:29,090 consumable and a purchase of hide ads which is non consumable. 145 00:08:29,170 --> 00:08:34,210 So we're actually going to go ahead and make a function called comp. And then we'll pass and the transaction 146 00:08:34,210 --> 00:08:40,070 will determine whether it comes from the meal or the purchase for hiding ads. 147 00:08:40,180 --> 00:08:45,160 And then we can either save the boolean value or not because buying food shouldn't have any impact on 148 00:08:45,160 --> 00:08:45,870 the ads. 149 00:08:46,090 --> 00:08:54,430 So let's actually write that function now called complete type phunk complete wups and incomplete. 150 00:08:54,430 --> 00:09:01,100 We're going to basically pass in a transaction of type S-K payment transaction. 151 00:09:01,930 --> 00:09:06,970 And inside this what we're going to do is we're going to use a switch to go through the transaction 152 00:09:07,450 --> 00:09:09,880 identifier so let's do that switch 153 00:09:12,580 --> 00:09:18,150 switch transaction dot payment. 154 00:09:18,610 --> 00:09:20,710 What does the identifier product identifier. 155 00:09:21,010 --> 00:09:23,170 And we're going to do a couple of different cases. 156 00:09:23,170 --> 00:09:28,990 One is IAP M.I.T. and we're going to break at the end. 157 00:09:29,230 --> 00:09:35,130 Then we have another case IAP hydrides adds ID and of course we're going to break at the end. 158 00:09:35,530 --> 00:09:36,620 So that's cool. 159 00:09:36,640 --> 00:09:39,240 So it's telling us the switch must be exhaustive. 160 00:09:39,240 --> 00:09:41,340 So we need to add a default case. 161 00:09:41,350 --> 00:09:42,670 And that's just going to break. 162 00:09:42,830 --> 00:09:43,180 OK. 163 00:09:43,180 --> 00:09:46,100 So anything else is going to break although we don't have anything else to pass in. 164 00:09:46,100 --> 00:09:48,910 So it's never going to get called but it's just a way to be safe. 165 00:09:48,910 --> 00:09:57,670 So now what we're going to do is if Mial idea is called We don't need to do anything but if someone 166 00:09:57,670 --> 00:10:00,640 buys this hide adds ID purchase. 167 00:10:00,640 --> 00:10:05,200 We need to be able to set that user defaults boolean to be true or false and we're going to set it to 168 00:10:05,200 --> 00:10:07,170 False later on. 169 00:10:07,390 --> 00:10:13,870 For instance if the app opens and they've never bought it before so we're going to go ahead and write 170 00:10:13,870 --> 00:10:25,360 a function to set that so-call funk set non consumable purchase status of type Boolean. 171 00:10:25,690 --> 00:10:26,240 All right. 172 00:10:26,350 --> 00:10:30,440 And you know what we don't need this parameter so we're going to just use an underscore. 173 00:10:31,060 --> 00:10:38,520 Now in order to actually set it we call user defaults dot standard set and take a look. 174 00:10:38,530 --> 00:10:43,720 We can set a value of type Boolean for a certain string and we're going to pass in the status from our 175 00:10:43,720 --> 00:10:47,580 function and the key is non consumable purchase was made. 176 00:10:47,590 --> 00:10:49,850 And I just paste it back so I saved it from before. 177 00:10:50,140 --> 00:11:01,450 So if IAP hydrides adds ID is called we're going to go ahead and call set non consumable purchase and 178 00:11:01,450 --> 00:11:07,510 it's going to be true and therefore this is going to be true and set in user default which is really 179 00:11:07,510 --> 00:11:08,530 cool. 180 00:11:08,530 --> 00:11:15,600 Now later we're going to use this to show or hide our ad in our detail visi. 181 00:11:15,790 --> 00:11:17,200 That's pretty neat. 182 00:11:17,200 --> 00:11:21,640 Now let's think if there are any other places that we should be thinking about using this. 183 00:11:21,640 --> 00:11:26,510 We come in oh well you know we need to call complete because otherwise we can't do anything. 184 00:11:26,770 --> 00:11:31,820 So go ahead and just call complete and the transaction is the transaction. 185 00:11:31,820 --> 00:11:34,050 So when we pass and hear from our for loop. 186 00:11:34,090 --> 00:11:38,480 So basically this should set our Boullion to be true. 187 00:11:38,830 --> 00:11:42,130 Yes that's cool so it gets set when we buy. 188 00:11:42,130 --> 00:11:43,750 Otherwise it's false by default. 189 00:11:44,140 --> 00:11:45,700 And that's great. 190 00:11:45,700 --> 00:11:48,350 So let's think how are we actually going to use this. 191 00:11:48,370 --> 00:11:51,790 We need a way to show or hide the ads. 192 00:11:51,790 --> 00:11:56,800 But what if you know someone has purchased the ad and they close out of the app and they go back in 193 00:11:57,280 --> 00:12:02,020 what are we going to use in order to actually show that person that their purchase was valid. 194 00:12:02,020 --> 00:12:07,240 We can basically create a variable that stores the value of that user defaults boolean and then use 195 00:12:07,240 --> 00:12:10,290 that to determine whether or not the ads are showing. 196 00:12:10,480 --> 00:12:15,280 So to do that we're going to make a private variable because no one else needs to use it except this 197 00:12:15,280 --> 00:12:16,160 class. 198 00:12:16,210 --> 00:12:21,540 So say private var hidden status type Boolean. 199 00:12:21,820 --> 00:12:29,710 It's going to be equal to user defaults dot standard dot Boolean for key and the key is non consumable 200 00:12:29,710 --> 00:12:33,640 purchase was made which of course returns a boolean obviously. 201 00:12:33,700 --> 00:12:35,900 So now we have a hidden status. 202 00:12:36,160 --> 00:12:40,630 And when the view appears we can use that property to tell whether or not the ad should be showing or 203 00:12:40,630 --> 00:12:40,930 not. 204 00:12:40,930 --> 00:12:43,960 So go ahead and say View will appeal. 205 00:12:44,680 --> 00:12:47,550 OK Super view will appear and pass in animated. 206 00:12:47,830 --> 00:12:53,560 Then we're going to go ahead and say ugly ad view is hidden and we're going to set it to be equal to 207 00:12:53,560 --> 00:12:58,690 hidden status because if it's either true or false it will show or hide then we're going to go ahead 208 00:12:58,720 --> 00:13:03,410 and set the ads button to hide ads button is hidden. 209 00:13:03,640 --> 00:13:07,860 It's going to be also a hidden status hidden status. 210 00:13:07,870 --> 00:13:08,730 There we go. 211 00:13:09,040 --> 00:13:13,480 So if we buy it and we bring up this view it's going to be hidden depending on whether or not we've 212 00:13:13,480 --> 00:13:15,550 bought it which is really cool. 213 00:13:15,730 --> 00:13:17,920 But let's think we need to set it. 214 00:13:17,950 --> 00:13:23,380 If it is actually purchased because remember when it's purchased that by item gets you know popped in 215 00:13:23,380 --> 00:13:25,740 here the meal is successfully purchased. 216 00:13:25,780 --> 00:13:29,180 But what if we bought hide hide ads. 217 00:13:29,590 --> 00:13:33,400 What if we bought the hide ads in at purchase what we're going to need to do is we're going to need 218 00:13:33,400 --> 00:13:36,920 to call this gay ugly ads. 219 00:13:36,920 --> 00:13:41,210 View is equal to a hidden status and you know what we can consolidate this into a function. 220 00:13:41,210 --> 00:13:43,510 Let's go ahead and put that right here. 221 00:13:43,760 --> 00:13:47,650 Funk and let's just say I don't know 222 00:13:50,390 --> 00:13:57,760 show or hide ads and we can just set that to be equal to hidden status. 223 00:13:57,770 --> 00:14:03,640 So let's go back and put it on view will appear show or hide ads. 224 00:14:03,650 --> 00:14:06,840 And then whenever it's called we're going to go ahead and just show or hide ads. 225 00:14:06,890 --> 00:14:10,940 So we don't need to copy the same code over and over again we can just call the function twice. 226 00:14:11,090 --> 00:14:15,940 So I don't know about you but I really want to go try this out let's build and run. 227 00:14:16,010 --> 00:14:19,340 Let's go see if it works when we buy our at purchase. 228 00:14:19,340 --> 00:14:21,790 And guys this is awesome. 229 00:14:21,800 --> 00:14:23,420 We're making so much progress. 230 00:14:23,540 --> 00:14:23,980 Here we go. 231 00:14:24,050 --> 00:14:27,140 So if I tap on a food item the ads are there. 232 00:14:27,230 --> 00:14:38,440 Now if I buy it if I tap by when I tap OK it should hide your purchase was successful but nothing happens. 233 00:14:38,440 --> 00:14:39,750 This is interesting. 234 00:14:39,760 --> 00:14:41,500 Now why would that be. 235 00:14:41,740 --> 00:14:44,630 It's saying that we are. 236 00:14:44,860 --> 00:14:46,480 Well you know what let's. 237 00:14:46,570 --> 00:14:50,890 We should actually be printing something to make sure that this is actually coming through de-bug print. 238 00:14:51,280 --> 00:14:58,240 And let's go ahead and just print out ads hidden and I'm actually going to go ahead and delete this 239 00:14:58,240 --> 00:15:03,020 app for my phone and rebuild it because now we're using user defaults and it wasn't using that before. 240 00:15:03,190 --> 00:15:06,500 So we're going to build in runs that we have a clean copy. 241 00:15:06,580 --> 00:15:12,730 Although I just deleted it while it was running so X code is going to get mad at me for quit that pull 242 00:15:12,730 --> 00:15:16,570 up an X code beta we go. 243 00:15:16,690 --> 00:15:17,020 All right. 244 00:15:17,020 --> 00:15:21,010 BuildOn Ron go back to our detailed Visi there. 245 00:15:21,340 --> 00:15:22,940 Oh and it didn't say my de-bug print. 246 00:15:23,080 --> 00:15:24,200 How nice. 247 00:15:27,470 --> 00:15:31,840 OK we're going to say ads hidden. 248 00:15:32,810 --> 00:15:33,680 And let's go ahead. 249 00:15:33,680 --> 00:15:35,400 I didn't build it with that in it. 250 00:15:35,410 --> 00:15:37,730 But let's go ahead and hide those ads. 251 00:15:38,000 --> 00:15:39,590 You can't see what I'm doing can you. 252 00:15:39,590 --> 00:15:40,720 Here we go. 253 00:15:40,760 --> 00:15:41,170 OK. 254 00:15:41,250 --> 00:15:43,600 Tap by tap. 255 00:15:43,650 --> 00:15:44,380 OK. 256 00:15:45,300 --> 00:15:50,970 And it says your purchase was successful although it's still not hiding. 257 00:15:51,090 --> 00:15:54,240 And the reason for that could be in our IP service. 258 00:15:54,240 --> 00:15:59,340 Let's see we are completing our transaction. 259 00:15:59,480 --> 00:16:02,220 K we are oh you know what. 260 00:16:02,260 --> 00:16:07,760 The notification is being sent before we're actually completing and setting this. 261 00:16:07,840 --> 00:16:10,350 So it's asking it to do something and to show and hide. 262 00:16:10,360 --> 00:16:12,360 But we have not yet actually said it. 263 00:16:12,400 --> 00:16:17,550 So let's go ahead and let's call complete before send notification Let's see if that helps. 264 00:16:17,590 --> 00:16:26,210 Let's build and run again and let's see if that helps with our issue here of setting that value IAP 265 00:16:26,310 --> 00:16:28,480 products Loden Here's our app. 266 00:16:28,590 --> 00:16:29,700 And let's see. 267 00:16:30,060 --> 00:16:31,050 And the ads are gone. 268 00:16:31,050 --> 00:16:31,700 Look at that. 269 00:16:31,740 --> 00:16:32,870 OK so that's good. 270 00:16:32,880 --> 00:16:36,930 Looks like it's working but I am going to go ahead and stop this. 271 00:16:36,930 --> 00:16:38,760 Delete the app really quickly. 272 00:16:38,760 --> 00:16:43,740 And we're going to build it one more time just to make sure that it is actually working the way that 273 00:16:43,740 --> 00:16:44,840 we are intending. 274 00:16:44,950 --> 00:16:45,580 OK. 275 00:16:46,080 --> 00:16:46,940 So here we go. 276 00:16:46,950 --> 00:16:49,900 It's up there it's running ads are here. 277 00:16:50,040 --> 00:16:59,890 Let's tap hide and buy already bought it and upon a successful purchase they're still not hiding. 278 00:16:59,900 --> 00:17:04,070 So that's interesting it looks though like it is working which is good. 279 00:17:04,490 --> 00:17:09,940 And when we call complete we are setting the non consumable purchase. 280 00:17:10,040 --> 00:17:13,910 And we know it's working because when we reloaded the app and went into the View Controller Actually 281 00:17:13,910 --> 00:17:15,380 I might be able to just do it like this. 282 00:17:15,380 --> 00:17:16,360 I just closed it. 283 00:17:16,580 --> 00:17:20,520 And if I go back in you'll see the ads are gone but they're not removing. 284 00:17:20,570 --> 00:17:21,440 When we buy it. 285 00:17:21,440 --> 00:17:23,600 So let's go back into detail visi. 286 00:17:23,780 --> 00:17:28,430 Let's figure out what the issue is when we purchase this. 287 00:17:28,430 --> 00:17:32,060 It says ads are hidden which That's cool. 288 00:17:32,060 --> 00:17:42,220 It calls show or hide adds and ugly ad is dependent on the hidden status which is initialized here. 289 00:17:42,460 --> 00:17:43,100 OK. 290 00:17:43,310 --> 00:17:50,210 We set it to be that boolean value which we actually set that in the previous few controllers so that's 291 00:17:50,330 --> 00:17:51,330 good. 292 00:17:51,860 --> 00:18:00,140 And oh you know what I just realized this is not working because when. 293 00:18:00,400 --> 00:18:00,850 Yeah. 294 00:18:00,880 --> 00:18:04,090 OK so hidden status is good for when we open the app up. 295 00:18:04,450 --> 00:18:11,470 But it's not good for when it's not good for when we are using it right on the screen because at that 296 00:18:11,470 --> 00:18:16,680 time this has already been instantiated with whatever value was saved when the app opens. 297 00:18:16,690 --> 00:18:19,230 So let's go ahead and let's actually change. 298 00:18:19,240 --> 00:18:19,710 Sure. 299 00:18:19,770 --> 00:18:26,830 Sure hide ads is fine for view will appear but in here we actually need to hard code this to have a 300 00:18:26,830 --> 00:18:28,120 different value. 301 00:18:28,150 --> 00:18:34,150 We're going to go ahead and type right here show or hide ads and if it's purchased we're going to set 302 00:18:34,240 --> 00:18:35,930 is hidden to true. 303 00:18:36,280 --> 00:18:38,020 And we're going to set is hidden to true. 304 00:18:38,260 --> 00:18:42,460 So we are sort of hard coding that in here but it's going to be able to make an instantaneous change 305 00:18:42,970 --> 00:18:45,560 as opposed to needing to quit the app and go back in. 306 00:18:45,580 --> 00:18:46,760 That's not a good experience. 307 00:18:46,870 --> 00:18:52,990 So close it and I'm going to delete it like so BuildOn run one more time and this should successfully 308 00:18:53,050 --> 00:18:56,470 allow us to purchase and hide those ads that I was talking about. 309 00:18:56,540 --> 00:19:03,750 We know it's going to pull up boom let's tap buy or hide ads for 99 tap by tap. 310 00:19:03,760 --> 00:19:04,500 OK. 311 00:19:06,030 --> 00:19:08,690 Do you see that boom ads are gone. 312 00:19:08,690 --> 00:19:11,210 They're saved into user defaults so we can go in. 313 00:19:11,210 --> 00:19:12,560 It's going to be gone. 314 00:19:12,560 --> 00:19:16,860 If I quit out of the app and go back in it's still gone. 315 00:19:16,870 --> 00:19:18,460 Look at that user default is awesome. 316 00:19:18,460 --> 00:19:24,920 So guys we now have non consumable purchases and consumable purchases completely finished. 317 00:19:24,940 --> 00:19:29,590 The only thing we need to do next is to set up our restore function which is going to allow us to restore 318 00:19:29,590 --> 00:19:32,980 our purchases if we downloaded the app on maybe a new phone or new device. 319 00:19:33,000 --> 00:19:35,550 We are so close to being done with this course guys. 320 00:19:35,560 --> 00:19:36,210 Amazing work. 321 00:19:36,210 --> 00:19:38,640 Let's move on to the next video. 322 00:19:38,650 --> 00:19:40,050 I'll see you there.
