1 00:00:05,980 --> 00:00:09,280 Have everyone Mark Price you're at DEF slopes duck. 2 00:00:09,940 --> 00:00:15,290 And let's go ahead and get our butts working so we can actually remove the advertisements so in our 3 00:00:15,290 --> 00:00:17,570 main storyboard. 4 00:00:17,780 --> 00:00:23,030 Open up the assistant editor and what we're going to do is a few things we're going to hold some references 5 00:00:23,030 --> 00:00:27,180 to these views here so we can remember to remove them when that purchase is made. 6 00:00:27,200 --> 00:00:31,610 And then we're also going to make an action for this button so let's do the action first since it's 7 00:00:31,610 --> 00:00:32,090 right here. 8 00:00:32,090 --> 00:00:33,430 Easy. 9 00:00:33,440 --> 00:00:33,920 All right. 10 00:00:33,930 --> 00:00:39,530 And we can call this an action and remove ads pressed. 11 00:00:39,720 --> 00:00:40,420 OK. 12 00:00:40,820 --> 00:00:48,860 And the other thing I want to do is make a ibl for this as well remove ads button. 13 00:00:49,440 --> 00:00:52,690 OK let's make two more outlets. 14 00:00:52,820 --> 00:00:55,310 Let's do a 15 00:00:58,170 --> 00:00:58,720 go on there. 16 00:00:58,760 --> 00:01:01,810 That's the button the banner that's the one. 17 00:01:02,080 --> 00:01:04,900 So there there's a banner of you and we're going to make an L. 18 00:01:04,910 --> 00:01:07,500 We're going to call this a we really have to be interviewed for mine. 19 00:01:07,990 --> 00:01:09,470 So that's good. 20 00:01:09,550 --> 00:01:13,710 And then what I did want to do is the actual view here itself. 21 00:01:13,930 --> 00:01:14,500 OK. 22 00:01:14,640 --> 00:01:16,850 Now this is just off the screen. 23 00:01:16,870 --> 00:01:17,480 What's going on. 24 00:01:17,620 --> 00:01:22,500 Notice the lines here on the view itself what I want to do is something a little bit different. 25 00:01:22,930 --> 00:01:25,770 I want to make an eye out for the constraint of the height. 26 00:01:25,930 --> 00:01:32,420 OK so let's open up the right hand side and make sure we do have a height constraint OK. 27 00:01:32,620 --> 00:01:40,270 So we've got this view and it's a C here so it's from the bottom to the top. 28 00:01:41,820 --> 00:01:44,900 To the left and to the right so it's kind of filling up that whole space. 29 00:01:44,910 --> 00:01:45,870 Well let's think about this here. 30 00:01:45,870 --> 00:01:47,400 What do we actually want to do. 31 00:01:47,790 --> 00:01:49,080 If we remove this. 32 00:01:49,200 --> 00:01:51,510 We're just going to have an empty space there. 33 00:01:51,540 --> 00:01:57,300 What we can do is we can remove it from the view but it might mess up our other constraints. 34 00:01:57,300 --> 00:02:07,810 So what if what if what we do is we just remove the views altogether instead of adjusting the constraints 35 00:02:07,870 --> 00:02:12,910 let's just remove the views from the screen and the reason why I was thinking about the constraints 36 00:02:14,070 --> 00:02:18,020 is because let me teach you how you would do this if you're actually working with the table view. 37 00:02:18,250 --> 00:02:20,730 So think about this here logically. 38 00:02:21,130 --> 00:02:23,780 You've got a table view here which is one or more rows. 39 00:02:23,980 --> 00:02:28,330 If you get rid of these buttons here you would have a big empty space here which is not what we want. 40 00:02:28,340 --> 00:02:33,640 We would want the table view to go all the way to the bottom so what you could do is on this view you 41 00:02:33,640 --> 00:02:34,890 set a height constraint. 42 00:02:34,990 --> 00:02:35,470 OK. 43 00:02:35,590 --> 00:02:36,340 And I'll show you how to do that. 44 00:02:36,340 --> 00:02:38,410 Right now we're not going to do it because I don't think it applies here. 45 00:02:38,410 --> 00:02:39,580 I think there's a better way. 46 00:02:39,580 --> 00:02:41,220 But I think this is good for you to know. 47 00:02:41,470 --> 00:02:44,710 So if you wanted to make your table you go all the way down to the bottom. 48 00:02:44,740 --> 00:02:50,440 When you remove these you go to your table view let's say let's say this was the Table View OK and what 49 00:02:50,440 --> 00:02:51,340 you could. 50 00:02:51,880 --> 00:02:53,470 Well let's see where is your interview. 51 00:02:53,590 --> 00:02:54,750 Well you could do on the banner view. 52 00:02:54,760 --> 00:03:00,040 Assuming that this top is the table view is you go not the banner of the view holder here itself the 53 00:03:00,040 --> 00:03:01,090 one that's holding the other views. 54 00:03:01,090 --> 00:03:06,340 You can go to the constraints and set a height constraint on the sky just for fun. 55 00:03:06,340 --> 00:03:07,270 We'll get rid of it. 56 00:03:07,420 --> 00:03:09,250 So see how the high is 112. 57 00:03:09,430 --> 00:03:16,570 You can actually control drag from your height constraint over here and let's just call this the ADD 58 00:03:16,600 --> 00:03:17,410 folder. 59 00:03:17,550 --> 00:03:19,240 Right. 60 00:03:19,330 --> 00:03:25,030 And what you can do is when it's time to remove the advertisements you could just say add folder height 61 00:03:25,310 --> 00:03:27,780 dark constant equals zero. 62 00:03:27,780 --> 00:03:32,770 And what would happen is it sets the constraint height to zero would shrink it basically making it making 63 00:03:32,770 --> 00:03:33,640 it invisible. 64 00:03:33,790 --> 00:03:37,350 And then your table view would automatically go down for you which is really cool. 65 00:03:37,360 --> 00:03:38,310 Again we're not doing that. 66 00:03:38,320 --> 00:03:42,370 We don't have a table view here and we're just going to deal with the white space and remove these. 67 00:03:42,370 --> 00:03:45,570 But that's how you would work it to get your view to expand all the way to the bottom. 68 00:03:45,570 --> 00:03:46,910 OK. 69 00:03:48,220 --> 00:03:51,100 Good stuff to know. 70 00:03:51,120 --> 00:03:53,330 Get rid of the ad Holder right. 71 00:03:53,430 --> 00:03:57,040 I mean to get rid of it here as well too. 72 00:03:57,350 --> 00:03:58,800 We don't need to hide on that. 73 00:03:59,290 --> 00:03:59,990 OK. 74 00:04:00,400 --> 00:04:03,480 So we got the remove ads button we've got this we can remove those both. 75 00:04:03,490 --> 00:04:04,980 Which is fine. 76 00:04:05,470 --> 00:04:06,740 And I think that's what we'll do. 77 00:04:06,760 --> 00:04:08,030 We'll just we'll just remove those. 78 00:04:08,020 --> 00:04:17,530 So let's go back to our code home Visi And let's just right the logic so when the app first loads what 79 00:04:17,530 --> 00:04:18,180 do we want to do. 80 00:04:18,180 --> 00:04:23,950 In our view controller Well we want to make sure that we want to make sure that the user is supposed 81 00:04:23,950 --> 00:04:25,410 to even see ads in the first place. 82 00:04:25,420 --> 00:04:26,050 How do we do that. 83 00:04:26,050 --> 00:04:33,200 Well simple enough we can say if the ads need to show how would we do that. 84 00:04:33,290 --> 00:04:38,270 We would just probably just check against the user defaults to see if the key there is for the purchase 85 00:04:38,420 --> 00:04:40,210 that we made. 86 00:04:40,290 --> 00:04:43,590 So let's do that. 87 00:04:44,250 --> 00:04:55,500 If user defaults that standard stream for key now we want the string for the bull for key. 88 00:04:55,580 --> 00:04:56,280 We said it true. 89 00:04:56,280 --> 00:05:05,830 So the bovver key and we're going to say purchase manager instance IP remove ads. 90 00:05:06,300 --> 00:05:12,330 So OK so if there's a ball for the key this could be nil right. 91 00:05:12,330 --> 00:05:15,870 So it could be a. 92 00:05:16,020 --> 00:05:27,210 What we should we should say if let show equals. 93 00:05:29,460 --> 00:05:33,620 So maybe this isn't the best way let's just do a Neal check here. 94 00:05:33,930 --> 00:05:40,080 I don't want to store this in a variable but we want to do just see if there's something there so if 95 00:05:40,870 --> 00:05:46,980 you're ready for saturable for key blah blah blah equals nil meaning it doesn't exist so if it doesn't 96 00:05:46,980 --> 00:05:49,550 exist we know we need to show the ads. 97 00:05:49,560 --> 00:05:50,670 And I did not want to do that. 98 00:05:50,670 --> 00:05:52,190 There we go. 99 00:05:52,230 --> 00:05:53,340 That will do it. 100 00:05:53,340 --> 00:05:57,150 So if it doesn't exist let's show the advertisements. 101 00:05:57,180 --> 00:05:58,050 No big deal. 102 00:05:58,290 --> 00:06:01,620 Ok really cool. 103 00:06:01,620 --> 00:06:02,720 But if it does exist. 104 00:06:02,760 --> 00:06:12,780 What we want to do well say else let's get rid of the ads so remove ads and say remove from Superville 105 00:06:13,230 --> 00:06:20,510 and let's say Vanner view remove from a preview let's just get rid of those out of this review altogether. 106 00:06:20,790 --> 00:06:27,640 If they have made that purchase cool I like it I like it I like it. 107 00:06:28,590 --> 00:06:31,580 You know that's fine. 108 00:06:31,610 --> 00:06:32,100 We're good. 109 00:06:32,110 --> 00:06:33,150 We're good. 110 00:06:33,450 --> 00:06:34,650 So that's our code here. 111 00:06:34,650 --> 00:06:36,730 And let's actually triggered the purchase now. 112 00:06:37,260 --> 00:06:40,330 So that should be as simple as saying right. 113 00:06:40,380 --> 00:06:49,000 So purchase an injured instance purchase remove ads but we have a problem right. 114 00:06:49,020 --> 00:06:50,670 So what is the problem here. 115 00:06:50,670 --> 00:06:55,850 The problem is we have no way of knowing when the purchase succeeds or when it fails. 116 00:06:56,190 --> 00:07:00,600 So what it means is we probably need some type of callback function and we can actually use a closure 117 00:07:00,600 --> 00:07:01,140 for this. 118 00:07:01,140 --> 00:07:07,450 And what I'm going to do is over here in our purchase manager I'm going to create one and I will put 119 00:07:07,470 --> 00:07:10,680 above the class so anybody can use it we'll put it up here actually. 120 00:07:10,910 --> 00:07:15,120 We're going to create a type alias we're going to give a name to this so type alias and we're going 121 00:07:15,120 --> 00:07:17,420 to call this completion handler. 122 00:07:17,430 --> 00:07:18,420 Right. 123 00:07:18,540 --> 00:07:28,410 And we're going to if it succeeds guess what we're saying here is it takes a parameter whether it succeeds 124 00:07:28,410 --> 00:07:31,040 or not and returns nothing. 125 00:07:31,290 --> 00:07:40,470 OK so now what we can do is when we are starting a purchased purchase remove ads we can actually put 126 00:07:40,470 --> 00:07:48,900 in a completion handler that can be passed in so uncomplete escaping escaping. 127 00:07:49,290 --> 00:07:54,570 And we're going to put a lot of time to completion handler. 128 00:07:54,600 --> 00:08:00,210 So what we're doing here is this closure syntax here we're making it as a parameter that can be passed 129 00:08:00,210 --> 00:08:00,890 in. 130 00:08:01,320 --> 00:08:01,620 OK. 131 00:08:01,620 --> 00:08:07,710 And this is really cool because now what we can do is look at this right here if payment you can make 132 00:08:07,710 --> 00:08:11,610 payments and products account is great in this or what if it's not well then we should consider a failure 133 00:08:12,030 --> 00:08:20,380 so we can say else and then we can sit on comp. like so we can pass false did not succeed. 134 00:08:20,520 --> 00:08:21,340 OK. 135 00:08:21,690 --> 00:08:23,000 Now here's something interesting though. 136 00:08:23,010 --> 00:08:25,020 So we say purchased remove ads. 137 00:08:25,080 --> 00:08:29,810 So we're going to call that from our view controller but look at this it ends right here. 138 00:08:29,940 --> 00:08:35,100 We're just adding the payment and then at some later point in time update transactional we call so how 139 00:08:35,100 --> 00:08:38,870 does update transactions no to call our callback function. 140 00:08:38,880 --> 00:08:40,260 Well it doesn't yet. 141 00:08:40,290 --> 00:08:44,870 So what we need to do is actually store a completion handler. 142 00:08:44,880 --> 00:08:54,590 So what we'll do is here will say our transaction complete like so and it can be of type completion 143 00:08:54,600 --> 00:09:00,510 handler will make it an optional because we don't know if it's going to be used or not or if the user 144 00:09:00,510 --> 00:09:02,760 doesn't our developer doesn't want to implement it's fine. 145 00:09:02,940 --> 00:09:12,290 And so we've got our uncomplete here false what we need to do here is say what a recall this transaction 146 00:09:12,290 --> 00:09:17,730 and complete comp. So we'll say transaction complete equals uncomplete. 147 00:09:17,760 --> 00:09:25,500 So we're just going to store a variable of the completion handler right here with me so far you're like 148 00:09:25,500 --> 00:09:25,920 now. 149 00:09:25,950 --> 00:09:27,710 Well just bear with me. 150 00:09:27,720 --> 00:09:29,560 You can always watch the video again. 151 00:09:29,660 --> 00:09:31,290 Just during a completion handler here. 152 00:09:31,290 --> 00:09:35,010 So our view controller can know when the transaction is complete. 153 00:09:35,040 --> 00:09:39,100 So then what we do is in our update transactions. 154 00:09:39,110 --> 00:09:39,510 OK. 155 00:09:39,540 --> 00:09:42,090 This is where we can say it's done. 156 00:09:42,150 --> 00:09:49,020 So if we succeeded with the purchase we're just going to say transaction complete. 157 00:09:49,020 --> 00:09:50,120 All right we're going to say. 158 00:09:50,280 --> 00:09:51,050 True. 159 00:09:51,300 --> 00:09:51,510 OK. 160 00:09:51,510 --> 00:09:54,500 So it succeeded in this case if it failed. 161 00:09:54,510 --> 00:09:57,580 Will say that it fell transaction complete. 162 00:09:58,050 --> 00:09:59,510 I would say false. 163 00:09:59,520 --> 00:10:00,630 It did not succeed. 164 00:10:00,750 --> 00:10:04,800 And then this one would be restored would be transaction complete. 165 00:10:04,800 --> 00:10:14,430 True because it succeeded in the transaction and we do want to make sure that we just catch every single 166 00:10:14,430 --> 00:10:19,830 case here for each transaction and transactions case first default. 167 00:10:20,010 --> 00:10:24,360 And so if we get to the default block I'm going to consider it a failure. 168 00:10:26,430 --> 00:10:28,330 So that would be a controller and no. 169 00:10:28,860 --> 00:10:30,410 Awesome. 170 00:10:30,510 --> 00:10:36,630 So now all we need to do is go back to our view controller here and call this function again but we've 171 00:10:36,630 --> 00:10:37,530 changed it around right. 172 00:10:37,530 --> 00:10:46,340 So it's a purchase move adds uncomplete just press enter and we're going to say this as a success. 173 00:10:47,180 --> 00:10:49,850 And let's get rid of the parentheses we don't need those. 174 00:10:50,160 --> 00:10:53,740 And there you have it so what's going to happen is we're going to call purchased remove ads. 175 00:10:53,960 --> 00:11:01,590 It's going to go to our purchase manager OK and we're storing the callback that we just passed in and 176 00:11:01,590 --> 00:11:02,300 you're like What do we do. 177 00:11:02,310 --> 00:11:06,590 What did we pass and well look here in the view controller we're passing this block here. 178 00:11:06,600 --> 00:11:07,410 I know it sounds weird. 179 00:11:07,410 --> 00:11:08,820 It's very weird syntax right. 180 00:11:08,820 --> 00:11:17,320 BLOCK syntax is are closer syntax is very weird but we were passing in this closure and so in our purchase 181 00:11:17,320 --> 00:11:19,940 manager we're storing that closure here. 182 00:11:20,070 --> 00:11:24,520 And then when the payment is actually done we finish it like so. 183 00:11:24,780 --> 00:11:25,350 OK. 184 00:11:25,390 --> 00:11:30,420 We call it which is going to pass a variable the boolean right in here. 185 00:11:30,660 --> 00:11:32,010 OK. 186 00:11:32,180 --> 00:11:37,080 No complex closures are very complex you don't have to understand it in order to know how to use them. 187 00:11:37,350 --> 00:11:39,000 And it just takes some time. 188 00:11:39,000 --> 00:11:41,360 Lots of times and done so right. 189 00:11:41,370 --> 00:11:42,430 So what do we do now. 190 00:11:42,450 --> 00:11:45,980 Now that we know when something succeeding or failing What do we do. 191 00:11:46,230 --> 00:11:50,520 Well first things first is when we actually purchased the remove ads. 192 00:11:50,520 --> 00:11:53,760 We probably should show a loadings for it or we're not going to do that. 193 00:11:53,790 --> 00:11:59,880 You can do that on your own time but it's called an ACH activity indicator. 194 00:11:59,880 --> 00:12:06,630 You can show a loading spin or activity indicator and then what we would do here is when we get the 195 00:12:06,630 --> 00:12:07,890 call back we should dismiss it. 196 00:12:07,890 --> 00:12:12,990 So you know we would dismiss the spinner and then what do we do. 197 00:12:13,020 --> 00:12:17,190 Well if it was successful we don't need parentheses in here. 198 00:12:17,190 --> 00:12:19,080 This isn't javascript. 199 00:12:19,080 --> 00:12:26,340 If it was successful we'll say self-taught banner ad or interview remove from Superville and we'll say 200 00:12:26,340 --> 00:12:35,720 self dot What was the purchase button but and move ads button remove from Super view. 201 00:12:35,730 --> 00:12:40,830 We'll just remove those from the Super view and we know that we're already storing it in the end user 202 00:12:40,830 --> 00:12:43,860 defaults from the purchase manager. 203 00:12:43,920 --> 00:12:45,340 So we don't need to do that here. 204 00:12:45,630 --> 00:12:50,650 And then of course if it was a failure what would you do you might give a message to the user so would 205 00:12:50,650 --> 00:12:59,580 be else no show message to the user why it failed and then they can take appropriate action. 206 00:13:00,000 --> 00:13:00,740 So cool. 207 00:13:00,870 --> 00:13:06,900 So remove ads press let's follow the chain of events we call the function and purchase the product which 208 00:13:06,900 --> 00:13:07,850 is up here. 209 00:13:07,980 --> 00:13:09,330 And then we start the payment. 210 00:13:09,450 --> 00:13:10,450 That's great. 211 00:13:10,620 --> 00:13:15,900 Remove ads product and then we store the completion handler and then if it's successful what do we do 212 00:13:16,290 --> 00:13:20,100 we set the user defaults here to true. 213 00:13:20,190 --> 00:13:24,390 And then we complete the transaction very very very very cool. 214 00:13:24,390 --> 00:13:26,070 So let's go ahead and run this. 215 00:13:26,100 --> 00:13:27,480 You've got to run it from your phone. 216 00:13:27,560 --> 00:13:28,030 OK. 217 00:13:28,080 --> 00:13:30,980 You've got to run it from your phone in order for this to work. 218 00:13:30,990 --> 00:13:36,800 So let's go ahead and get it set up here on our phone. 219 00:13:37,310 --> 00:13:40,190 I just realized that our our logic here is incorrect. 220 00:13:40,210 --> 00:13:41,960 It's giving us a warning here. 221 00:13:42,200 --> 00:13:47,450 Let's fix this so I forgot the object for key can return nil. 222 00:13:47,450 --> 00:13:51,440 But if you're working with a boolean it'll actually return true or false no matter even if the key exists 223 00:13:51,440 --> 00:13:51,680 or not. 224 00:13:51,680 --> 00:13:52,130 So that's good. 225 00:13:52,130 --> 00:13:55,750 All we need to do is adjust this slightly so. 226 00:13:56,030 --> 00:14:00,430 So if it's true that's all we needed to say like that. 227 00:14:00,440 --> 00:14:06,290 Or rather we can just probably do that let's build it and determine it as true or false since it's a 228 00:14:06,290 --> 00:14:07,790 native value type. 229 00:14:07,790 --> 00:14:11,840 So rather than again seeing if it's nil it won't be nil. 230 00:14:11,840 --> 00:14:16,580 It'll give you a true or false value only for only for native value types like bullion here. 231 00:14:16,580 --> 00:14:20,230 So if it's true it means we've saved it there. 232 00:14:20,240 --> 00:14:20,780 Great. 233 00:14:20,810 --> 00:14:27,560 Well it means actually means the opposite we need to move this code. 234 00:14:27,740 --> 00:14:37,130 Yeah if it exists it means that's what it means if it exists it will return true which means remove 235 00:14:37,130 --> 00:14:38,750 the ads because we've purchased it. 236 00:14:38,750 --> 00:14:41,910 Otherwise it will return false. 237 00:14:41,930 --> 00:14:43,890 That's our logic here. 238 00:14:46,870 --> 00:14:47,610 Wonderful. 239 00:14:47,790 --> 00:14:48,320 OK. 240 00:14:48,550 --> 00:14:50,700 That is good. 241 00:14:50,710 --> 00:14:56,760 Now what we're gonna do is run on our device and it has to be ran on a device simulator does not work. 242 00:14:57,460 --> 00:14:57,700 OK. 243 00:14:57,700 --> 00:14:58,650 So there's our ads. 244 00:14:58,660 --> 00:14:59,220 That's great. 245 00:14:59,220 --> 00:15:02,940 Everything is running just as it should. 246 00:15:03,230 --> 00:15:03,820 OK. 247 00:15:03,970 --> 00:15:09,190 So with your app running in order for us to properly test this you're going to need to log out of your 248 00:15:09,610 --> 00:15:10,600 iTunes account. 249 00:15:10,600 --> 00:15:16,120 You've got to now use that sandbox tester so what I want you to do is close the app or just go to the 250 00:15:16,120 --> 00:15:19,910 home screen and then go to the App Store. 251 00:15:20,650 --> 00:15:27,670 And what you're going to do is click if you're on the if you're on a previous version earlier than iOS 252 00:15:27,790 --> 00:15:32,320 11 you're going to go to the Home tab of the store and go all the way to the bottom. 253 00:15:32,320 --> 00:15:36,760 Otherwise go to your Updates tab and click your profile picture and what you're going to do is sign 254 00:15:36,760 --> 00:15:37,960 out of your account. 255 00:15:38,320 --> 00:15:38,790 OK. 256 00:15:38,890 --> 00:15:42,650 So sign out of your iTunes account and then go back to the app. 257 00:15:43,020 --> 00:15:43,620 OK. 258 00:15:46,270 --> 00:15:50,080 And now that you're back in the app you can actually sign in with a tester account. 259 00:15:50,080 --> 00:15:55,850 So if I click the remove ads button it's asking us to sign in. 260 00:15:55,860 --> 00:15:59,060 It's asking us because Apple's prompting it because we're going to make a purchase. 261 00:15:59,070 --> 00:16:05,250 I'm going to use my existing Apple I.D. which was testor one two three the one that we created 1 2 three 262 00:16:08,880 --> 00:16:15,360 have slopes to come put in a password and clicking by 263 00:16:19,240 --> 00:16:21,330 sometimes has issues we'll try again. 264 00:16:23,160 --> 00:16:29,250 I always find that there's issues with with making purchases and test accounts it usually takes a few 265 00:16:29,250 --> 00:16:31,010 time so we're going to try again. 266 00:16:33,780 --> 00:16:34,660 There we go. 267 00:16:34,740 --> 00:16:40,550 It's asking us if we want to buy remove ads for 399 which we do. 268 00:16:40,860 --> 00:16:41,570 You're all set. 269 00:16:41,570 --> 00:16:42,950 Your purchase was successful. 270 00:16:42,950 --> 00:16:43,420 And look at that. 271 00:16:43,420 --> 00:16:44,480 It worked. 272 00:16:44,480 --> 00:16:46,030 Everything in our entire process worked. 273 00:16:46,030 --> 00:16:49,290 So we went through the process we signed in with a test account we made the purchase. 274 00:16:49,370 --> 00:16:53,240 It showed the sandbox purchase even had a little square braces that said sandbox. 275 00:16:53,360 --> 00:17:00,230 And then it came back and hit our callback function and it removed the advertisements for us. 276 00:17:00,230 --> 00:17:02,110 Pretty darn cool. 277 00:17:02,710 --> 00:17:03,000 OK. 278 00:17:03,020 --> 00:17:07,790 So here in our view controller we came all the way back here and in the success and are removed and 279 00:17:07,790 --> 00:17:08,900 you notice how it took a while. 280 00:17:08,960 --> 00:17:12,160 Which is why you need to show a loading spin or some type of pop up to your user. 281 00:17:12,260 --> 00:17:16,570 So it's a nice elegant experience so we successfully made a purchase. 282 00:17:16,620 --> 00:17:18,070 So we're going to call this video done. 283 00:17:18,080 --> 00:17:22,370 And in the next video we're going to wrap up by restoring in-app purchases in the case that the user 284 00:17:22,370 --> 00:17:26,960 has deleted their device so are their app from the device so that's it for now. 285 00:17:26,960 --> 00:17:28,870 Mark Price at does slopes dot com. 286 00:17:28,880 --> 00:17:30,710 Let's move forward.
