1 00:00:05,900 --> 00:00:08,650 Hey what's up everyone Mark Price here at the slopes dot com. 2 00:00:08,660 --> 00:00:14,060 Let's go ahead and just get started making in-app purchases so what I want to do is a little bit of 3 00:00:14,060 --> 00:00:17,550 code cleanup as usual I want to create a new group here. 4 00:00:17,630 --> 00:00:23,390 Just call this controller or control or files in there like view control or at Swift and then I'm going 5 00:00:23,390 --> 00:00:28,650 to open the view control or file click the name and rename it to something more useful. 6 00:00:28,650 --> 00:00:33,130 Let's for instance call this a home VC and press enter. 7 00:00:33,140 --> 00:00:40,040 So and now I want to create a services folder because what I want to do is create in that purchase service 8 00:00:40,110 --> 00:00:49,770 that will manage all the in-app purchases for us so services and we're going to say new file swift and 9 00:00:49,770 --> 00:00:55,380 let's go ahead and call this the purchase manager purchase manager. 10 00:00:55,380 --> 00:00:57,630 Yeah that sounds good. 11 00:00:57,810 --> 00:01:10,840 And then class purchase manager like so and we're going to say static let VAR or not are static let 12 00:01:10,870 --> 00:01:14,840 instance what I meant to say equals purchase manager. 13 00:01:14,850 --> 00:01:19,170 So what we're doing here is we're creating a singleton we're creating one instance of this class in 14 00:01:19,170 --> 00:01:22,550 memory that will be used for the lifetime of the application. 15 00:01:22,740 --> 00:01:26,310 So we can always access it easily without having to create new copies of it. 16 00:01:26,310 --> 00:01:33,230 And one more thing we need to do here is import store kit so we can actually use the at Purchase store 17 00:01:33,240 --> 00:01:36,320 get stuff with me so far. 18 00:01:36,490 --> 00:01:36,850 OK. 19 00:01:36,860 --> 00:01:40,590 So the next thing we need to do is forward in with in-app purchases. 20 00:01:40,620 --> 00:01:46,020 Our class is going to have to need to work with this object. 21 00:01:46,080 --> 00:01:48,800 So I want to put an object here as the parent class. 22 00:01:49,050 --> 00:01:53,340 And what we're going to do is we're going implement some protocols we're going to implement S-K products 23 00:01:53,460 --> 00:02:01,230 request delegate like so and S-K payment transaction observer. 24 00:02:01,620 --> 00:02:02,150 OK. 25 00:02:02,220 --> 00:02:06,950 Those are two very common protocols that work with when working with in-app purchases. 26 00:02:07,080 --> 00:02:07,920 OK. 27 00:02:08,190 --> 00:02:10,420 And what do we want to do. 28 00:02:10,560 --> 00:02:13,700 Well we want to work with in-app purchases but we haven't created any yet. 29 00:02:13,710 --> 00:02:18,260 And also by the way we can click this red button here and they'll implement the functions for us here 30 00:02:18,270 --> 00:02:19,340 which is great. 31 00:02:19,540 --> 00:02:23,610 Move these down so they're where they should be. 32 00:02:23,610 --> 00:02:29,780 So we need to create an app purchase so let's go back to our browser and let's go back to our app. 33 00:02:29,790 --> 00:02:32,970 So iTunes Connect my apps 34 00:02:36,010 --> 00:02:43,060 and what we're going to do is go to Daily Dose depth slopes features in-app purchases and we're going 35 00:02:43,060 --> 00:02:49,540 to create the purchase that's going to be used in our app are just going to be a non consumable OK and 36 00:02:49,540 --> 00:02:54,550 non consumable means that you can only purchase it once which is what we want. 37 00:02:54,640 --> 00:03:00,790 Consumable can be purchased many times like coins for a game things like that in our deficit. 38 00:03:01,240 --> 00:03:03,810 We've had consumable coin purchases. 39 00:03:03,820 --> 00:03:05,630 You can use coins to buy courses. 40 00:03:05,650 --> 00:03:07,390 There's many different ways of making purchases. 41 00:03:07,390 --> 00:03:13,030 You can do auto renewable subscriptions or non renewing subscriptions where you just pay it once up 42 00:03:13,030 --> 00:03:14,000 in advance. 43 00:03:14,230 --> 00:03:17,380 And those are few of the ways you can monetize in your apps. 44 00:03:17,380 --> 00:03:22,990 We're going to create a non consumable click Create reference name is just a reference for you and we're 45 00:03:22,990 --> 00:03:26,690 going to call this remove ads and what's the product. 46 00:03:26,710 --> 00:03:30,820 This is important this is the idea you're going to reference in your code and you should use the same 47 00:03:30,820 --> 00:03:33,610 type of bundle that your app is using. 48 00:03:33,610 --> 00:03:41,980 So calm the slopes got a daily dose not remove ads. 49 00:03:42,010 --> 00:03:44,080 That's what I'm going to call it the price. 50 00:03:44,080 --> 00:03:53,320 Let's make it 399 and content hosting content hosting is when Apple will actually host your purchase 51 00:03:53,350 --> 00:03:57,150 you can upload a package file with information about your purchases. 52 00:03:57,160 --> 00:03:58,440 And so they can host it. 53 00:03:58,510 --> 00:04:03,190 And the reason why you might do this is let me give you a perfect example let's think of the app the 54 00:04:03,390 --> 00:04:05,540 soaps app where you can purchase many courses. 55 00:04:05,620 --> 00:04:09,470 We don't want to have 500 in-app purchases one for every course. 56 00:04:09,490 --> 00:04:12,340 That would be too hard to manage and we'd have to keep making updates. 57 00:04:12,340 --> 00:04:17,240 So instead what we do is we would make let's say five in-app purchases we just with different prices 58 00:04:17,270 --> 00:04:22,350 $25 $29 course purchase purchased course purchase of course purchased just with different price values. 59 00:04:22,710 --> 00:04:23,180 Okay. 60 00:04:23,290 --> 00:04:27,940 And when you buy those you buy them great but what about when you like restore your in-app purchases. 61 00:04:27,940 --> 00:04:33,050 How does it know which courses to give back unless you have your own server managing this. 62 00:04:33,070 --> 00:04:33,900 It's impossible. 63 00:04:33,910 --> 00:04:40,600 So what you can do is you can upload metadata about purchases and it's up to Apple and the host for 64 00:04:40,600 --> 00:04:40,900 you. 65 00:04:40,960 --> 00:04:42,850 And then they'll deliver it to you when you need it. 66 00:04:42,850 --> 00:04:45,030 So you can manage things like that. 67 00:04:45,100 --> 00:04:47,960 We're not going to be doing that pretty complex actually. 68 00:04:48,190 --> 00:04:52,420 And then we have localizations of the different languages that you want to display your purchase name 69 00:04:52,420 --> 00:04:58,870 to Apple of course is the more languages that you translate for or localized in the more cells you will 70 00:04:58,870 --> 00:04:59,350 get. 71 00:04:59,350 --> 00:05:03,570 We are only doing English today because that is the only language that I know. 72 00:05:03,730 --> 00:05:05,280 So the display. 73 00:05:05,290 --> 00:05:07,960 This is what the user is going to see when they make the purchase. 74 00:05:08,140 --> 00:05:17,270 Remove ads and the description permanently remove ads is what we're going to make the description say. 75 00:05:17,530 --> 00:05:26,500 Lastly we do need to have a screenshot here so they can look at the app and so they can look at the 76 00:05:26,500 --> 00:05:28,720 app and say hey where's the purchase. 77 00:05:28,720 --> 00:05:36,610 So what we can do is click our simulator here command s to save a screenshot and let's just drag that 78 00:05:36,620 --> 00:05:44,170 screenshot from the desktop over here into the Choose file slot and you want to give the app review 79 00:05:44,190 --> 00:05:49,350 some notes you have to click the green button to remove ads. 80 00:05:57,720 --> 00:05:59,270 Perfect that has loaded. 81 00:05:59,370 --> 00:06:04,320 And when you're all done here go ahead and we're going to copy this idea by the way and we're going 82 00:06:04,320 --> 00:06:05,540 to click safe. 83 00:06:05,970 --> 00:06:08,090 OK your IT purchase is ready to submit. 84 00:06:08,120 --> 00:06:11,590 If if it said something else like missing made it did it you probably missed something here. 85 00:06:11,700 --> 00:06:17,520 But if it's ready to submit what you can do is go back to the App Store now click your first version 86 00:06:17,520 --> 00:06:21,750 here 1.0 or whatever version you want to submit this with. 87 00:06:21,750 --> 00:06:25,630 Scroll down and in-app purchases. 88 00:06:25,630 --> 00:06:29,740 You want to add all of your in-app purchases here and if you created it correctly you'll see here it 89 00:06:29,740 --> 00:06:34,210 did not create correctly it means or if you don't see here it means it was not created correctly and 90 00:06:34,210 --> 00:06:36,900 there's something missing you need to go back and fix it. 91 00:06:36,910 --> 00:06:41,810 Ours is here which is great so I'm going to click done and then I'm going to click save everything that 92 00:06:41,810 --> 00:06:42,570 we've just done. 93 00:06:42,590 --> 00:06:45,080 You have to do even to test in-app purchases. 94 00:06:45,080 --> 00:06:45,570 OK. 95 00:06:45,740 --> 00:06:49,880 If you do not do all of these steps you can even test it and you're going to run into problems so what 96 00:06:49,880 --> 00:06:50,840 did we do. 97 00:06:50,840 --> 00:06:51,320 OK. 98 00:06:51,470 --> 00:06:55,760 Remember we went into the apps or we clicked features we created a new that purchased them we went back 99 00:06:55,760 --> 00:07:00,980 to the apps or we clicked prepare for submission and we added the in-app purchases to this version so 100 00:07:01,070 --> 00:07:04,460 it can be reviewed by the app by the App Store Team. 101 00:07:04,580 --> 00:07:05,320 OK. 102 00:07:05,840 --> 00:07:06,270 So cool. 103 00:07:06,270 --> 00:07:09,590 We're now ready to work with in-app purchases. 104 00:07:09,590 --> 00:07:13,460 So back in the code okay we can start writing code to work with them. 105 00:07:13,460 --> 00:07:19,580 So first things first is I want to actually store the ID of the in-app purchases here so let IAP move 106 00:07:19,610 --> 00:07:21,910 as equals. 107 00:07:21,980 --> 00:07:26,900 You know if you had more than one minute purchase you would store the ID here or if you are building 108 00:07:26,900 --> 00:07:31,190 a more elegant solution you can actually store all these IDs on your server and you can fetch them from 109 00:07:31,190 --> 00:07:36,260 your server and then you can add more in-app purchases dynamically which is really cool without having 110 00:07:36,260 --> 00:07:37,310 to wait for app. 111 00:07:37,460 --> 00:07:42,920 The app store review OK but ours is going to be hard coded because we only have one game. 112 00:07:43,070 --> 00:07:43,910 Are you with me so far. 113 00:07:43,910 --> 00:07:51,100 So here's are in that purchase and I think we're ready to get started on this. 114 00:07:51,200 --> 00:07:54,140 So let's create a few variables. 115 00:07:54,380 --> 00:08:04,140 We're going to create one called Product request products requests type Eskay products request. 116 00:08:04,150 --> 00:08:11,220 This is going to be requests that not with an S zoomie a request that we send up to the app store K 117 00:08:11,390 --> 00:08:17,470 to get products that are actually going to store an array of products like cell escape product 118 00:08:22,180 --> 00:08:26,710 because after all we're seeing you back all of your product IDs and it comes in the form of an escape 119 00:08:26,710 --> 00:08:27,400 product. 120 00:08:27,490 --> 00:08:28,240 Right. 121 00:08:28,270 --> 00:08:32,030 And the reason why we store these IDs here is so we can match them up. 122 00:08:32,050 --> 00:08:37,730 OK so we can match what we get from the App Store to what we have here in our code. 123 00:08:37,760 --> 00:08:38,390 All right. 124 00:08:38,440 --> 00:08:40,780 So those are products requesters our products. 125 00:08:40,780 --> 00:08:41,900 Great. 126 00:08:41,950 --> 00:08:47,170 The very first thing that we want to do is actually fetch the products we cannot make and end up purchase 127 00:08:47,210 --> 00:08:49,050 unless you have the products from the App Store. 128 00:08:49,090 --> 00:08:51,790 Let me say that again you can't make a purchase. 129 00:08:51,910 --> 00:08:56,230 No user can make a purchase unless the app has spoken to the App Store and actually downloaded your 130 00:08:56,230 --> 00:08:59,650 product IDs for your specific app so we have to do that. 131 00:08:59,680 --> 00:09:02,870 So phunk fetch products. 132 00:09:03,010 --> 00:09:11,230 All right we're going to create a set here so product IDs so which product IDs we want to fetch equals 133 00:09:11,300 --> 00:09:13,040 an asset. 134 00:09:13,330 --> 00:09:15,190 We're going to do the one that says object. 135 00:09:15,190 --> 00:09:19,300 We're going to go ahead and pass in that purchase remove ads. 136 00:09:19,300 --> 00:09:25,790 We're going to cast this as the regular set just the way you got to do it. 137 00:09:26,400 --> 00:09:26,700 OK. 138 00:09:26,720 --> 00:09:30,250 So we have a set of product that is that's how Apple wants them. 139 00:09:30,250 --> 00:09:33,490 Is it an asset or a set of some kind. 140 00:09:33,490 --> 00:09:36,670 And then what we're going to do is we're going to save our request so a product request 141 00:09:39,100 --> 00:09:47,740 products request and we're going to say equals Eskay products request and it wants the product identifiers 142 00:09:47,770 --> 00:09:48,690 and wants that set. 143 00:09:48,710 --> 00:10:00,940 So let's go ahead and create the set so product IDs and then products request delegate equals self care 144 00:10:01,810 --> 00:10:07,290 and products requests dot start. 145 00:10:07,300 --> 00:10:11,620 All right so what's going to happen is you're saying hey let's go fetch some products. 146 00:10:11,650 --> 00:10:13,320 Here's the list of products that I have. 147 00:10:13,360 --> 00:10:16,780 Apple can you go get them for me maybe you don't know all of them maybe have some old one deprecated 148 00:10:16,780 --> 00:10:17,350 ones. 149 00:10:17,410 --> 00:10:19,630 You're letting apple know which products that you want. 150 00:10:19,840 --> 00:10:20,110 OK. 151 00:10:20,110 --> 00:10:23,930 And you make the requests you set the delegate and you click start when you do the delegate. 152 00:10:24,150 --> 00:10:24,530 OK. 153 00:10:24,550 --> 00:10:28,780 It's going to call this function here products request function when it's done. 154 00:10:28,900 --> 00:10:33,010 OK so this function here we don't need to do anything else and when it when the request is done after 155 00:10:33,010 --> 00:10:35,260 we started it we'll call this function. 156 00:10:35,260 --> 00:10:36,400 All right which is cool. 157 00:10:36,700 --> 00:10:40,720 So let's go ahead and make sure that when the app first loads that we're starting the fetch on our products 158 00:10:40,720 --> 00:10:44,180 because we want it to be ready by the time the user actually clicks the button. 159 00:10:44,200 --> 00:10:51,110 So we'll go to the app delegate and what we'll do is here we will say purchase manager for instance 160 00:10:51,330 --> 00:10:54,950 that fetch products the moment the app loads. 161 00:10:54,970 --> 00:10:57,910 All right let's just get all this set up and ready to go. 162 00:10:58,390 --> 00:11:04,330 So now that we've started the request how do we actually store the data when it comes down et cetera. 163 00:11:05,460 --> 00:11:09,730 What we'll do is in here and this function did receive response. 164 00:11:09,810 --> 00:11:10,640 Okay. 165 00:11:11,240 --> 00:11:16,870 When you say response products that count was greater than zero meaning did it find products if there's 166 00:11:16,890 --> 00:11:21,160 more than one great let's go ahead and start working with them and then we're just going to store them. 167 00:11:21,330 --> 00:11:26,810 Products equals response products. 168 00:11:28,290 --> 00:11:31,050 We're not doing a whole lot here with this. 169 00:11:31,050 --> 00:11:33,660 And so I do want to show you something which is really interesting. 170 00:11:33,660 --> 00:11:36,100 OK so response that products count. 171 00:11:36,270 --> 00:11:36,640 OK. 172 00:11:36,660 --> 00:11:40,110 So what is a product that it's giving us here. 173 00:11:40,610 --> 00:11:41,880 It's a type Eskay product. 174 00:11:41,880 --> 00:11:48,180 Well if you look at S.K. product OK there's a there's a title a price a price location product identifier 175 00:11:48,210 --> 00:11:51,600 etc. etc. etc. and you're like Mark why is this important. 176 00:11:51,600 --> 00:11:53,690 Well think about this. 177 00:11:53,880 --> 00:11:58,640 You say you have literally used the dove slopes example let's say you're selling 10 courses and they'll 178 00:11:58,650 --> 00:12:00,980 have different prices and different product IDs. 179 00:12:01,120 --> 00:12:01,910 OK. 180 00:12:02,390 --> 00:12:04,820 Where were you getting the pricing information from. 181 00:12:04,970 --> 00:12:08,540 Well the pricing information has to match what's on Apple's server. 182 00:12:08,550 --> 00:12:15,540 And so Apple needs to send you that information right so you can actually display it in your purchased 183 00:12:15,600 --> 00:12:16,400 icons. 184 00:12:16,410 --> 00:12:20,250 Oh OK so you don't manually write the prices yourself in the code. 185 00:12:20,250 --> 00:12:20,750 No. 186 00:12:20,820 --> 00:12:24,360 You get those prices from the App Store so you can display them to the user. 187 00:12:24,360 --> 00:12:28,680 In our case we're not doing that because we're just clicking a button here that says remove ads but 188 00:12:28,680 --> 00:12:32,550 you do have that information available to you here inside your products. 189 00:12:32,550 --> 00:12:33,020 OK. 190 00:12:33,030 --> 00:12:38,970 Every one of these products has a price and title etc. all coming from the apps are all what you created. 191 00:12:38,970 --> 00:12:39,960 All right. 192 00:12:40,150 --> 00:12:45,570 And all we're doing here is actually just just storing the one in that purchase that we have and where 193 00:12:45,720 --> 00:12:47,650 we can make a purchase later on. 194 00:12:48,030 --> 00:12:49,070 No big deal. 195 00:12:49,190 --> 00:12:49,750 OK. 196 00:12:52,040 --> 00:12:55,310 So that looks good to see if it's actually working. 197 00:12:55,340 --> 00:13:08,240 What we can do is in here we can print response products debug description came something very important. 198 00:13:08,300 --> 00:13:13,790 You need to know right now you cannot test in-app purchases on the simulator. 199 00:13:13,790 --> 00:13:16,550 Again you cannot test in-app purchases on the simulator. 200 00:13:16,760 --> 00:13:18,700 Even the request to fetch products won't work. 201 00:13:18,710 --> 00:13:20,470 It will not work in the simulator store. 202 00:13:20,490 --> 00:13:27,260 It does not work in the simulator so if you don't have a device you can't test in-app purchases and 203 00:13:27,260 --> 00:13:31,820 I would never ever recommend submitting an app to the apps or unless you have a device and you've actually 204 00:13:31,820 --> 00:13:32,500 tested it. 205 00:13:32,510 --> 00:13:37,700 So make sure your device is selected and what we're going to do is we're going to look for this print 206 00:13:37,700 --> 00:13:43,280 statement saying which products it was able to pull up from the App Store someone or run it now. 207 00:13:43,340 --> 00:13:49,550 So we can see and again the app delegate is being called to start the fetch products and that should 208 00:13:49,550 --> 00:13:54,870 start this which goes here to the products requests and it will give us a response. 209 00:13:54,890 --> 00:13:58,170 The app is now active and working perfect. 210 00:13:58,170 --> 00:14:03,670 Let's stop it let's look at our prints here. 211 00:14:03,800 --> 00:14:08,860 I saw something that some Google print outs here 212 00:14:11,700 --> 00:14:14,140 and there it is it did return one product for us. 213 00:14:14,220 --> 00:14:15,640 So it's definitely working. 214 00:14:15,690 --> 00:14:22,160 Our one product has been fetched from the iTunes store and we've printed it here. 215 00:14:22,230 --> 00:14:27,120 And so clearly we're receiving an object so let's go ahead and call this video done what we've done 216 00:14:27,120 --> 00:14:31,520 here is we've implemented a connection to the iTunes App Store. 217 00:14:31,650 --> 00:14:37,380 We've successfully fetched one of our advertisements or excuse me one of our in-app purchases by via 218 00:14:37,820 --> 00:14:44,310 via of this idea here and we started the request to fetch the products and we received them right here 219 00:14:44,310 --> 00:14:48,150 and stored them in a variable so we can reference them at a later point in time and make purchase. 220 00:14:48,150 --> 00:14:49,450 So that's it for now. 221 00:14:49,450 --> 00:14:51,400 Marc price Adela's slopes dot com. 222 00:14:51,450 --> 00:14:52,520 Let's move on. 223 00:14:52,650 --> 00:14:53,080 And for.
