1 00:00:07,120 --> 00:00:12,280 Hey everybody what's going on says Caleb with Dev slopes com and in this video we're going to talk about 2 00:00:12,280 --> 00:00:14,620 how do we handle a successful purchase. 3 00:00:14,620 --> 00:00:18,520 How do we handle a failure payment deferred et cetera et cetera. 4 00:00:18,550 --> 00:00:23,080 How are we going to manage that and how are we going to notify our application that these certain things 5 00:00:23,080 --> 00:00:23,990 have happened. 6 00:00:24,010 --> 00:00:28,590 We're going to dive into it right now and let's pull open our project and let's check it out. 7 00:00:28,600 --> 00:00:34,370 So to begin we're actually going to need to go into our IAP service so click on that. 8 00:00:34,540 --> 00:00:40,240 And then inside of the IAP service what we're going to do is we're going to scroll down to where we 9 00:00:40,240 --> 00:00:42,760 basically handle our payment request. 10 00:00:42,760 --> 00:00:49,490 So scroll down all the way here to where we basically conform to S-K payment transaction observer. 11 00:00:49,570 --> 00:00:54,460 Now inside of the payment queue we go through a switch for the transaction state. 12 00:00:54,460 --> 00:00:59,770 So let's say that I attempted to purchase something and the purchase failed maybe I canceled the purchase. 13 00:00:59,770 --> 00:01:02,320 Maybe my phone crashed or something. 14 00:01:02,320 --> 00:01:07,330 What it's going to do is it's going to switch through it's going to go ahead and go to Case whoops case 15 00:01:07,330 --> 00:01:08,320 failed. 16 00:01:08,320 --> 00:01:14,050 It's going to finish the transaction and send a notification for failed and that this is a very important 17 00:01:14,050 --> 00:01:14,440 function. 18 00:01:14,440 --> 00:01:15,780 I'm going to show you this now. 19 00:01:15,970 --> 00:01:18,290 So it's down at the very bottom of the View Controller. 20 00:01:18,400 --> 00:01:26,170 And here we have send notification for status and that comes from purchase status which is another enumeration 21 00:01:26,470 --> 00:01:34,870 now purchased restored and failed are three different ways that we can basically say hey we purchased 22 00:01:34,870 --> 00:01:40,150 something we restored something or we failed something but we're going to actually add a fourth case 23 00:01:40,240 --> 00:01:44,720 here and we're going to add case subscribed because that's another thing. 24 00:01:44,800 --> 00:01:49,120 If we purchase the food item that's one thing but subscribing is entirely different. 25 00:01:49,120 --> 00:01:53,410 So we're going to set another case here to be able to differentiate those different things. 26 00:01:53,410 --> 00:01:58,390 Now let's go back to IP service and you're going to notice if I build this it's going to say this switch 27 00:01:58,420 --> 00:02:03,840 is not exhaustive and that's because we're not handling what happens in the instance of a subscription. 28 00:02:04,030 --> 00:02:12,090 So go ahead and call case dot and look at that subscriber shows up put a call in and press enter. 29 00:02:12,100 --> 00:02:14,800 And now this is where all the good stuff is going to happen. 30 00:02:14,800 --> 00:02:20,410 For now we're just going to break but we're going to go ahead and add a custom notification here that 31 00:02:20,410 --> 00:02:24,670 will be posted as soon as a subscription successfully happens. 32 00:02:24,670 --> 00:02:25,260 OK. 33 00:02:25,570 --> 00:02:31,480 So you'll notice that there are some constants here that are saved IAP service purchase notification 34 00:02:31,810 --> 00:02:35,380 IAP service restore an IP service failure. 35 00:02:35,380 --> 00:02:40,120 Now if you go into constants and take a look you'll notice that I've just saved these here to have the 36 00:02:40,120 --> 00:02:41,710 same string value. 37 00:02:41,710 --> 00:02:45,670 Now we're going to go ahead and create another one for what happens if we subscribe. 38 00:02:45,670 --> 00:02:47,800 That means our subscription information has changed. 39 00:02:47,800 --> 00:02:50,110 Either we have subscribed we haven't. 40 00:02:50,110 --> 00:02:52,660 Maybe our subscription expired et cetera et cetera. 41 00:02:52,660 --> 00:03:04,720 So go ahead and type let IAAPA service subscribed status changed notification. 42 00:03:05,110 --> 00:03:08,300 That's super long Let's just say. 43 00:03:09,950 --> 00:03:13,330 IAP sub info changed. 44 00:03:13,340 --> 00:03:14,410 That's a little better. 45 00:03:14,780 --> 00:03:21,800 Press equals and go ahead and create a string of the same name IAP sub info change notification and 46 00:03:21,860 --> 00:03:23,420 let's leave it at that. 47 00:03:23,420 --> 00:03:32,720 So back into the IP service we're going to go ahead and call notification center like so default will 48 00:03:32,720 --> 00:03:36,850 access the default notification center and we're going to post a notification. 49 00:03:36,880 --> 00:03:43,700 Okay so go ahead and type post and we're going to choose the one with the name and an object. 50 00:03:43,920 --> 00:03:44,210 Okay. 51 00:03:44,210 --> 00:03:48,710 So go ahead and type an s notification 52 00:03:51,680 --> 00:03:59,790 name and then inside the parentheses we're going to call IAP and it's going to be not available because 53 00:03:59,790 --> 00:04:01,070 we've not built it yet. 54 00:04:01,230 --> 00:04:04,490 IAP sub There it is. 55 00:04:04,500 --> 00:04:07,560 IAP sub info changed notification. 56 00:04:07,560 --> 00:04:10,440 Now the object is actually going to be a boolean. 57 00:04:10,500 --> 00:04:11,040 OK. 58 00:04:11,340 --> 00:04:17,580 And the reason for that being is we're either going to say are we subscribed or are we not. 59 00:04:17,610 --> 00:04:20,620 Or maybe is our subscription valid or is it expired. 60 00:04:20,820 --> 00:04:26,100 And so what I'm going to do is I'm actually going to modify my function here because if you look we 61 00:04:26,100 --> 00:04:31,140 can pass in a status which is mandatory and an identifier which is optional. 62 00:04:31,140 --> 00:04:37,140 The reason for that is because if our payment is restored it doesn't matter what it was it's just going 63 00:04:37,140 --> 00:04:39,010 to restore everything that we've already bought. 64 00:04:39,210 --> 00:04:43,920 If it's failed it doesn't matter what object it came from because we just need to know that the payment 65 00:04:43,920 --> 00:04:44,610 failed. 66 00:04:44,730 --> 00:04:49,310 If we're subscribed we need to know is it valid or is it expired. 67 00:04:49,320 --> 00:04:52,890 And so we're going to use a boolean but we're not currently passing in a boolean. 68 00:04:53,040 --> 00:04:55,880 So we're going to add a new property here. 69 00:04:56,160 --> 00:05:02,730 So we're going to say send notification for status with identifier or Boullion and we're going to use 70 00:05:02,730 --> 00:05:05,950 bhool as an internal parameter of type Boolean. 71 00:05:06,260 --> 00:05:06,810 OK. 72 00:05:07,080 --> 00:05:10,060 Now pass in Bhool as the object here. 73 00:05:10,380 --> 00:05:15,630 And that is what we're going to use to to post our subscription notification. 74 00:05:15,630 --> 00:05:16,580 It's pretty cool. 75 00:05:16,890 --> 00:05:18,690 Now you're going to notice some issues. 76 00:05:18,720 --> 00:05:24,930 It's going to say that we are missing some arguments and we are because we're calling send notification 77 00:05:24,930 --> 00:05:25,790 right here. 78 00:05:26,100 --> 00:05:31,920 Now of course we are calling it where we are making our purchase and this is another thing we need to 79 00:05:31,920 --> 00:05:34,970 think about when we send the notification. 80 00:05:34,980 --> 00:05:40,470 This is for only a purchase but how are we going to differentiate between a purchase of a subscription 81 00:05:40,560 --> 00:05:43,780 and a purchase of just like a meal or hide ads. 82 00:05:43,980 --> 00:05:44,450 To do that. 83 00:05:44,450 --> 00:05:48,450 We're actually going to get rid of this function and put it inside the complete function. 84 00:05:48,450 --> 00:05:55,130 So go ahead and cut this like so and then go find the complete function like so. 85 00:05:55,310 --> 00:05:55,600 OK. 86 00:05:55,710 --> 00:05:57,620 Check it out inside. 87 00:05:57,760 --> 00:05:58,820 Complete. 88 00:05:58,980 --> 00:06:06,200 We're going to go ahead and use our switch to find either our hide adds ID or our subscription ID. 89 00:06:06,420 --> 00:06:12,830 So I'm going to add a new case right at the top case IAP mealtime monthly sub. 90 00:06:13,020 --> 00:06:17,270 OK because remember these are all for the product identifier on iTunes Connect. 91 00:06:17,460 --> 00:06:20,000 So go ahead and put a colon press enter. 92 00:06:20,010 --> 00:06:25,200 And what we're going to do is we're going to go ahead and basically copy and paste in what we just copied 93 00:06:25,200 --> 00:06:28,850 from above which is send notification for status purchased. 94 00:06:28,860 --> 00:06:31,170 But remember this is a subscription. 95 00:06:31,170 --> 00:06:35,330 And we have a special identifier just for that. 96 00:06:35,430 --> 00:06:37,490 We have dot subscribed. 97 00:06:37,710 --> 00:06:41,910 OK Bill to make sure that that's good to go and it's going to say we're missing a parameter which we 98 00:06:41,910 --> 00:06:43,430 are so click fix. 99 00:06:43,680 --> 00:06:51,780 And remember for our mealtime monthly sub if we are successful what we need to be doing is we basically 100 00:06:51,780 --> 00:06:52,560 need to pass in. 101 00:06:52,560 --> 00:06:53,080 True. 102 00:06:53,100 --> 00:06:55,900 Right because we are successful we did buy it. 103 00:06:56,040 --> 00:07:01,590 And so then it's going to go ahead and pass in that bullion as the notifications object which is awesome. 104 00:07:01,830 --> 00:07:07,230 Now at the very end since we're in a switch we need to break so that it knows to get out of it and then 105 00:07:07,230 --> 00:07:13,230 we also need to think if we are purchasing something we need to send a notification that this meal has 106 00:07:13,230 --> 00:07:16,750 been purchased so we can put that in IAP meal ID. 107 00:07:17,040 --> 00:07:20,840 And this one works right because we are sending it in as a purchase. 108 00:07:20,850 --> 00:07:22,200 Very very cool. 109 00:07:22,680 --> 00:07:23,880 So that should be good. 110 00:07:23,880 --> 00:07:25,640 We need to add our identifier here. 111 00:07:25,650 --> 00:07:28,410 And for this one we don't need to pass in a boolean. 112 00:07:28,410 --> 00:07:31,130 So let's just say nil we don't need it. 113 00:07:31,290 --> 00:07:32,970 Very very cool. 114 00:07:32,970 --> 00:07:36,820 So let's think what do we need to do next. 115 00:07:36,840 --> 00:07:38,910 We need to make sure that all our errors are gone. 116 00:07:39,040 --> 00:07:42,090 OK so click fix for restored. 117 00:07:42,090 --> 00:07:45,460 This is what is called After we successfully restore everything. 118 00:07:45,660 --> 00:07:52,140 We're going to send the restored notification with no identifier and no booleans so passen Nelle we 119 00:07:52,140 --> 00:07:53,300 have to fix this. 120 00:07:53,310 --> 00:07:58,740 It's going to say nyl is not compatible with argument type bool. 121 00:07:58,740 --> 00:08:00,510 Why is that. 122 00:08:00,990 --> 00:08:07,110 Oh that's because we didn't make this optional whoops that should be optional and this may ask us to 123 00:08:07,110 --> 00:08:08,520 force enwrap. 124 00:08:08,800 --> 00:08:09,570 I don't believe it will. 125 00:08:09,570 --> 00:08:10,130 OK. 126 00:08:10,530 --> 00:08:16,290 So missing argument let's add it in let's see failed does not matter. 127 00:08:16,480 --> 00:08:24,160 So put in nil and now it looks like we are doing pretty good here so we make a purchase. 128 00:08:24,240 --> 00:08:30,960 The purchase is finished we call comp. And based on that we send a notification saying hey we successfully 129 00:08:30,960 --> 00:08:31,620 subscribed. 130 00:08:31,620 --> 00:08:33,230 Very very cool. 131 00:08:33,390 --> 00:08:35,070 But there's something else. 132 00:08:35,100 --> 00:08:40,130 Remember a subscription had a perk it automatically hid the ads for us. 133 00:08:40,140 --> 00:08:46,890 So what we're going to do is we're going to also call set non consumable purchase to be true when we 134 00:08:46,890 --> 00:08:47,850 make a subscription. 135 00:08:47,850 --> 00:08:54,550 So go ahead and actually we're going to copy this like so and we're going to go ahead and paste it beneath. 136 00:08:54,600 --> 00:08:58,110 So we're doing both We're sending a notification for scription. 137 00:08:58,120 --> 00:09:01,920 We're also setting the non consumable purchase to be true. 138 00:09:02,050 --> 00:09:02,690 OK. 139 00:09:03,010 --> 00:09:03,960 Very very cool. 140 00:09:04,150 --> 00:09:05,860 So that's awesome. 141 00:09:06,160 --> 00:09:06,640 Let's think. 142 00:09:06,640 --> 00:09:10,850 Is there anything else we should do we may have to come back and look at stuff later. 143 00:09:11,050 --> 00:09:12,550 But I think that's pretty good. 144 00:09:12,550 --> 00:09:17,440 When we when we subscribe we're going to send a notification we're going to set that non consumable 145 00:09:17,440 --> 00:09:19,060 purchase to be true. 146 00:09:19,240 --> 00:09:24,830 And we're basically going to be able to hide the ads when we subscribe which is very very cool. 147 00:09:24,850 --> 00:09:30,460 So let's go ahead and let's set up an observer for this notification so we can see if it's actually 148 00:09:30,460 --> 00:09:32,240 working when we make a subscription. 149 00:09:32,290 --> 00:09:37,510 So go ahead and head into storefront Visi because that's where our subscribed button is and click on 150 00:09:37,510 --> 00:09:37,940 it. 151 00:09:37,990 --> 00:09:43,990 And then what we're going to do is in view did load We're going to set up another notification observer 152 00:09:43,990 --> 00:09:44,760 here. 153 00:09:44,770 --> 00:09:51,370 Now this one is for when a purchase is restored and as you can see when show restored alert is called 154 00:09:51,370 --> 00:09:55,800 it presents an alert basically saying hey your purchases were successfully restored. 155 00:09:56,110 --> 00:10:00,760 We're going to basically set up a function that will be able to determine whether or not we are valid 156 00:10:00,790 --> 00:10:02,100 in our subscription. 157 00:10:02,230 --> 00:10:08,630 So to do this let's create another observer by typing notification center default. 158 00:10:08,810 --> 00:10:15,730 Our observer can we're going to choose the one here with an observer selector name an object and the 159 00:10:15,730 --> 00:10:20,910 observer is self or this view controller the selector will come back to in a second. 160 00:10:21,070 --> 00:10:24,720 The name we're just going to use an S notification name. 161 00:10:24,790 --> 00:10:29,680 But then in parentheses following it we're going to put in our subscription notification because that's 162 00:10:29,680 --> 00:10:31,990 the one that gets posted when we subscribe. 163 00:10:32,020 --> 00:10:39,070 So type IAP sub info change notification and the object we can just say it's nil because that will actually 164 00:10:39,070 --> 00:10:41,560 be passed through in the next notification. 165 00:10:41,890 --> 00:10:47,890 So for the selector we need to write a function that will do a certain behavior or perform a certain 166 00:10:47,890 --> 00:10:50,800 action whenever that notification is posted. 167 00:10:50,800 --> 00:10:59,800 So let's actually write that function now by typing phunk subscription status was changed. 168 00:11:00,570 --> 00:11:01,500 OK. 169 00:11:01,630 --> 00:11:04,560 And basically we need to think what are we going to do here. 170 00:11:04,750 --> 00:11:06,700 We get a value passed in. 171 00:11:06,730 --> 00:11:13,150 If you remember when we subscribe we pass in a boolean either true or false. 172 00:11:13,270 --> 00:11:19,330 And that is accessible to us in the notification that's sent now to access that what we can do is we 173 00:11:19,330 --> 00:11:24,110 can go ahead and set up a parameter of type notification. 174 00:11:24,160 --> 00:11:27,930 So to do that I'm just going to put an underscore because the name doesn't really matter. 175 00:11:28,120 --> 00:11:31,940 But I am going to give an internal parameter of notification. 176 00:11:32,540 --> 00:11:35,650 OK and that's going to be of type notification like I said. 177 00:11:36,040 --> 00:11:41,950 Now in order to actually access the object of bullion that's passed in we can go ahead and create a 178 00:11:41,950 --> 00:11:46,000 constant that pulls out the object from the notification. 179 00:11:46,060 --> 00:11:54,480 So to be safe I'm going to use guard Latt by typing guard let let's just say status equals notification. 180 00:11:54,640 --> 00:11:57,490 OK the one we passed in object. 181 00:11:57,520 --> 00:12:00,580 Check that out as a boolean. 182 00:12:00,730 --> 00:12:06,100 OK but since this is a guard but we need to provide another option so else meaning if that doesn't work 183 00:12:06,160 --> 00:12:09,850 if we don't get a value we're just going to return get out of this function. 184 00:12:09,850 --> 00:12:11,000 Keep us from crashing. 185 00:12:11,140 --> 00:12:11,810 OK. 186 00:12:12,100 --> 00:12:12,960 So that's great. 187 00:12:12,970 --> 00:12:19,230 But otherwise we will have a boolean value in this status and we can basically create two conditions 188 00:12:19,450 --> 00:12:23,700 if status is true do one thing if status is not true do another thing. 189 00:12:23,840 --> 00:12:28,000 Let's set that up if status is true. 190 00:12:30,350 --> 00:12:31,660 Else. 191 00:12:32,180 --> 00:12:39,370 And this is where we're going to perform actions for success with let's say active subscription 192 00:12:42,560 --> 00:12:48,620 and this is where we're going to go ahead and perform actions for expired subscription and we'll get 193 00:12:48,620 --> 00:12:49,570 to that in a moment. 194 00:12:49,730 --> 00:12:54,120 But for now let's see what can we do we could print. 195 00:12:54,140 --> 00:13:02,730 Let's go ahead and call de-bug print and we'll just say subscription valid. 196 00:13:03,080 --> 00:13:03,920 OK. 197 00:13:04,580 --> 00:13:10,450 And for expired we'll say subscription expired and there is that. 198 00:13:10,460 --> 00:13:11,610 That's our function. 199 00:13:11,630 --> 00:13:16,220 But we're getting an error up here or we will if we try to build saying that we have you know a blank 200 00:13:16,260 --> 00:13:18,790 boiler plate code still sitting in there. 201 00:13:19,100 --> 00:13:22,180 And so to do that we're going to type LB selector. 202 00:13:22,550 --> 00:13:27,140 And if you know anything about selectors we can just pass in the name of a function and that basically 203 00:13:27,140 --> 00:13:29,810 sets it up to call a certain function for us. 204 00:13:29,810 --> 00:13:33,980 So that function is subscription status was changed. 205 00:13:33,980 --> 00:13:39,150 Press enter and the cool thing is that remember that this parameter here is of type notification. 206 00:13:39,320 --> 00:13:42,780 It'll automatically get passed in thanks to notification center. 207 00:13:42,830 --> 00:13:49,130 Now it's giving us an error saying that the argument Selecta refers to instance method that's not exposed 208 00:13:49,130 --> 00:13:50,250 to Objective-C. 209 00:13:50,450 --> 00:13:51,360 Click Fix. 210 00:13:51,370 --> 00:13:53,550 And what that's going to do. 211 00:13:53,660 --> 00:13:55,150 Whoops there we go. 212 00:13:55,160 --> 00:14:01,130 It's basically going to add at BJC to the front of our function just exposing it to the object C code 213 00:14:01,130 --> 00:14:03,960 that X code needs to process this. 214 00:14:03,980 --> 00:14:05,660 So that was a lot of code. 215 00:14:05,660 --> 00:14:07,060 Let's go ahead and build and run this. 216 00:14:07,070 --> 00:14:12,860 And let's go see if this fixed are not fixed but let's see if when we subscribe if the notification 217 00:14:12,890 --> 00:14:14,800 is successfully sent. 218 00:14:14,990 --> 00:14:17,310 Ok so I'm going to go ahead and build and run this. 219 00:14:17,330 --> 00:14:20,330 I'm going to go ahead and show you my simulator device. 220 00:14:20,630 --> 00:14:22,070 And here we go. 221 00:14:22,220 --> 00:14:30,970 So you can see this I can see this when I tap on the dollar sign like so it asks for our password so 222 00:14:30,970 --> 00:14:31,860 let's type that in. 223 00:14:31,860 --> 00:14:34,620 Test test one two three exclamation mark 224 00:14:37,610 --> 00:14:43,960 OK so it says subscribe to meal plan this subscription will automatically renew every month for forty 225 00:14:43,960 --> 00:14:45,700 nine ninety nine. 226 00:14:45,700 --> 00:14:46,780 Press continue. 227 00:14:47,830 --> 00:14:52,960 And it says this subscription will continue unless cancelled in settings at least one day before a subscription 228 00:14:52,960 --> 00:14:54,180 period ends. 229 00:14:54,190 --> 00:15:01,980 Press OK and when we press OK it should purchase OK so when we purchased it boom we finished the transaction. 230 00:15:01,990 --> 00:15:04,780 We call complete complete is here. 231 00:15:04,900 --> 00:15:05,280 OK. 232 00:15:05,290 --> 00:15:11,640 It will be IAP monthly sub meaning we'll send our notification and we will set our purchase to be true 233 00:15:11,650 --> 00:15:19,540 so the ads should go away now send notification for subscribed is going to post our notification which 234 00:15:19,600 --> 00:15:24,500 in storefront Visi we have an observer for that notification. 235 00:15:24,730 --> 00:15:29,520 When something is sent using that notification we're going to pass it in here. 236 00:15:29,680 --> 00:15:34,690 If it's true meaning if the subscription is true we're going to get subscription valid. 237 00:15:34,690 --> 00:15:36,970 Otherwise we'll get subscription expired. 238 00:15:37,000 --> 00:15:38,560 So go ahead and push. 239 00:15:38,560 --> 00:15:39,880 OK. 240 00:15:40,720 --> 00:15:43,820 And let's see if we get a nice little print statement here. 241 00:15:44,450 --> 00:15:46,780 I pushed OK sorry you couldn't see that on my screen. 242 00:15:46,800 --> 00:15:50,610 But all that happened was it popped up saying your purchase was successful. 243 00:15:50,610 --> 00:15:53,880 We get a notification saying subscription valid check that out. 244 00:15:53,880 --> 00:15:55,080 That's cool. 245 00:15:55,080 --> 00:16:03,010 And we also got our success message from our IP service which is right here purchased was successful. 246 00:16:03,150 --> 00:16:04,690 That is so cool. 247 00:16:04,830 --> 00:16:11,160 And now if I rebuild my app you'll notice that my subscription is still valid. 248 00:16:11,160 --> 00:16:15,680 Now if I pull up one of the controllers you'll notice the ads are gone. 249 00:16:15,750 --> 00:16:23,310 It successfully saved so remember we set our non-consumer consumable purchase to be true and that basically 250 00:16:23,490 --> 00:16:29,130 went into user defaults and it set true for our non consumable purchase was made. 251 00:16:29,250 --> 00:16:32,530 And that's going to basically allow us to hide those ads. 252 00:16:32,550 --> 00:16:40,800 OK because in detail we see we have a variable called Hidden status that gets its value from that exact 253 00:16:40,860 --> 00:16:47,310 same user defaults boolean and we use that to basically determine whether or not the ads should show 254 00:16:47,310 --> 00:16:48,360 or hide. 255 00:16:48,380 --> 00:16:51,180 OK that's pretty cool. 256 00:16:51,180 --> 00:16:54,260 So let's think what can we do next. 257 00:16:54,270 --> 00:16:59,770 What can we do to you know show that this is an ad subscription that we have a valid subscription. 258 00:17:00,000 --> 00:17:04,050 Let's go ahead and let's think I'm going to actually go to my storyboard and we're going to brainstorm 259 00:17:04,140 --> 00:17:09,480 what we can do to actually show whether or not this is a valid subscription. 260 00:17:09,480 --> 00:17:13,950 And I think what I want to do actually is I want to put a label here that says subscription valid or 261 00:17:13,950 --> 00:17:15,080 subscription expired. 262 00:17:15,090 --> 00:17:17,710 So let's drag that on really fast. 263 00:17:17,860 --> 00:17:24,660 You can't type you label drag it on and make sure that it does not touch the collection view. 264 00:17:24,690 --> 00:17:27,930 But it goes below like like that and I'm going to drag it. 265 00:17:27,930 --> 00:17:31,270 So it's nice and big 50 points high. 266 00:17:31,590 --> 00:17:37,710 And let's go ahead and let's pin that to the left bottom and right and give it a fixed height of 50. 267 00:17:37,710 --> 00:17:41,520 There we go Center the font and change it to Avenir next. 268 00:17:41,550 --> 00:17:42,990 That's my favorite font. 269 00:17:42,990 --> 00:17:44,180 I mean you can use whatever you want. 270 00:17:44,190 --> 00:17:50,160 But anyway and I'm going to bump it up to 24 and set it to be bold. 271 00:17:50,430 --> 00:17:51,310 OK. 272 00:17:51,390 --> 00:17:54,180 Now this will say updating. 273 00:17:54,750 --> 00:17:59,820 And basically depending on whether or not our subscription is active or expired we're going to set it 274 00:17:59,820 --> 00:18:02,390 so that it changes the font and color accordingly. 275 00:18:02,610 --> 00:18:07,740 Now Black is pretty intense of a color here so I think what I'm actually going to do is I'm actually 276 00:18:07,740 --> 00:18:09,770 going to choose a nice dark gray. 277 00:18:09,930 --> 00:18:11,530 That's a little less intense. 278 00:18:11,610 --> 00:18:15,020 I chose tungsten or if you want to know it's just six threes. 279 00:18:15,150 --> 00:18:16,210 That's pretty cool. 280 00:18:16,500 --> 00:18:21,390 So there we go our updating label is here but we should connect this to The View Controller so that 281 00:18:21,390 --> 00:18:28,470 we can properly update the label and we need to so open the assistant editor here and go ahead and pull 282 00:18:28,530 --> 00:18:38,070 up to the top right click on the label and drag it here and we're going to say subscription subscription 283 00:18:38,130 --> 00:18:42,650 status label. 284 00:18:42,840 --> 00:18:43,920 Press connect. 285 00:18:43,950 --> 00:18:46,740 And now we have access to that label. 286 00:18:46,870 --> 00:18:48,850 It will show updating by default. 287 00:18:48,990 --> 00:18:52,830 And now we're going to move on and head over to the next video where we're going to start customizing 288 00:18:52,890 --> 00:18:58,920 the experience of our app as well as preventing users from stealing this subscription. 289 00:18:59,160 --> 00:19:03,390 If you know anything about the jailbreak scene with iPhones there are ways to get around paying for 290 00:19:03,390 --> 00:19:04,350 in-app purchases. 291 00:19:04,440 --> 00:19:08,990 But we're going to make sure that people cannot do that by verifying the receipt with Apple. 292 00:19:09,000 --> 00:19:10,030 Very very cool. 293 00:19:10,140 --> 00:19:14,880 Let's head over to the next video and let's start doing that right now.
