1 00:00:05,910 --> 00:00:11,410 Hey everyone welcome to the last exciting video in working with in-app purchases. 2 00:00:11,550 --> 00:00:12,360 My name is Mark price. 3 00:00:12,360 --> 00:00:17,760 In case you forgot and we are going to finish this up so what we want to do is first get our restore 4 00:00:17,760 --> 00:00:20,680 in-app purchases button on our storyboard. 5 00:00:21,150 --> 00:00:26,610 And again the point of restoring in our purchases is in the case that someone deletes their app and 6 00:00:26,610 --> 00:00:30,110 they re install it your app and reasons reinstalls it. 7 00:00:30,120 --> 00:00:31,600 They need to be able to get their purchases back. 8 00:00:31,620 --> 00:00:36,480 And this is an apple requirement if you do not implement restore in-app purchases your app will be rejected 9 00:00:36,930 --> 00:00:42,090 of course with consumables or excuse me non consumables with consumables that doesnt matter. 10 00:00:42,090 --> 00:00:48,550 But if you have a one time non-consentual purchase you have to restore it or Apple will reject you. 11 00:00:48,870 --> 00:00:57,660 So put a button up here at the top and take out the word button like so and we are going to go ahead 12 00:00:57,660 --> 00:01:07,740 and put in the restore button here and I'm going to pin it to the top 10 from the right give it a fixed 13 00:01:07,740 --> 00:01:14,100 width and height just make it nice and easy and we're going to open the assistant editor and just simply 14 00:01:14,100 --> 00:01:18,430 make an IB action done this before no big deal. 15 00:01:20,500 --> 00:01:28,580 Put it about this one button and control drag and this is going to be an action and we're going to call 16 00:01:28,580 --> 00:01:30,220 this restore. 17 00:01:30,230 --> 00:01:34,750 But in pressed close the assistant editor. 18 00:01:35,060 --> 00:01:37,230 Let's look at our code here. 19 00:01:37,850 --> 00:01:40,110 Store button press cleanup. 20 00:01:40,400 --> 00:01:43,940 And what we're you going to do is we're going to have a function in our purchase manager so let's pretend 21 00:01:43,940 --> 00:01:52,650 the function exists and we're going to say purchase manager instance dot. 22 00:01:53,210 --> 00:01:56,660 Well this is great at first because we're gonna need to put a callback in there. 23 00:01:56,660 --> 00:01:57,350 It's all good. 24 00:01:57,440 --> 00:01:59,520 Let's go to purchase manager and do that now. 25 00:01:59,900 --> 00:02:09,350 So we'll do the same thing as this but we'll change the name of the function and we're going to call 26 00:02:09,350 --> 00:02:14,120 this store purchases like so. 27 00:02:14,510 --> 00:02:15,760 OK. 28 00:02:15,770 --> 00:02:21,020 And now what we can do is we can go back to the home PC and call that function so will say purchase 29 00:02:21,020 --> 00:02:24,580 manager for instance restore purchases. 30 00:02:24,620 --> 00:02:32,330 And just like before we'll create or little completion handler Here success and there we have it. 31 00:02:32,330 --> 00:02:35,990 So when that's done we'll be able to restore. 32 00:02:36,020 --> 00:02:41,690 And of course if it was failed you could say well you don't have purchases to restore things like that. 33 00:02:41,780 --> 00:02:43,460 So we're just kind of handling all the cases there. 34 00:02:43,460 --> 00:02:45,400 So what do we need to do. 35 00:02:45,500 --> 00:02:51,610 Go back to our purchase manager and actually just write the code to restore it and purchase so purchased 36 00:02:51,620 --> 00:02:54,180 manager or store purchases. 37 00:02:54,530 --> 00:03:03,630 And if Eskay payment you can make payments you always check that. 38 00:03:05,420 --> 00:03:08,160 And what did you say else. 39 00:03:09,320 --> 00:03:16,560 Okay so if we can make payments and then let's go ahead and store transaction complete equals on comp. 40 00:03:16,580 --> 00:03:18,650 let's store that callback handler. 41 00:03:18,800 --> 00:03:19,520 Okay. 42 00:03:19,880 --> 00:03:24,650 And then if it fails or if you can't make payments we'll say on complete and we'll say false. 43 00:03:24,650 --> 00:03:30,380 So they can't make a payment so we obviously can't restore the purchases which is fine and then we're 44 00:03:30,380 --> 00:03:31,110 storing this here. 45 00:03:31,120 --> 00:03:36,270 So let's go ahead and say S-K payment Eskay payment. 46 00:03:36,290 --> 00:03:45,550 Q default at looks at herself as an observer let's say self and then let's say S-K payment. 47 00:03:45,550 --> 00:03:51,560 Q That default restore completed transactions. 48 00:03:51,740 --> 00:03:52,700 Wonderful. 49 00:03:52,790 --> 00:03:58,200 So as similar as we did before we're adding ourself as an observer for this particular payment or transaction. 50 00:03:58,430 --> 00:04:02,120 And then we're calling the restore completed transaction which is going to go to Apple and is going 51 00:04:02,120 --> 00:04:08,870 to do all the work under the hood for us to see which transactions need to be restored if any at all. 52 00:04:09,030 --> 00:04:09,730 Okay. 53 00:04:09,980 --> 00:04:15,010 And so back down here in our restored section now we can just finish this up. 54 00:04:15,020 --> 00:04:16,230 No big deal. 55 00:04:16,340 --> 00:04:25,100 We're going to say if transaction payment type product identifier equals IAP remove ads. 56 00:04:25,520 --> 00:04:31,670 So if it equals the remove ads all we have to do is what we've done before. 57 00:04:31,910 --> 00:04:37,890 Saving the transaction with the user default so we can just copy this line of code here to save that 58 00:04:37,910 --> 00:04:40,370 purchase like so. 59 00:04:40,610 --> 00:04:41,160 OK. 60 00:04:41,480 --> 00:04:44,050 And then we can just call the callback handler. 61 00:04:44,060 --> 00:04:48,430 So transaction what's already here actually right here. 62 00:04:50,590 --> 00:04:51,690 That's cool. 63 00:04:51,770 --> 00:04:55,140 That's yeah I like that a lot. 64 00:04:55,140 --> 00:04:57,210 Let's just leave it there. 65 00:04:57,450 --> 00:04:59,590 We'll leave it there as is. 66 00:05:00,220 --> 00:05:02,790 Because let's assume that there was more than one in that purchase. 67 00:05:02,790 --> 00:05:07,730 You know we would want to do all of them check all of them and then call the transaction complete. 68 00:05:07,830 --> 00:05:09,320 So that's fine. 69 00:05:09,360 --> 00:05:13,550 I like this we just setting the standard defaults to true on this completion Hendershot and then we 70 00:05:13,580 --> 00:05:16,860 go back here to the home visi. 71 00:05:17,100 --> 00:05:18,120 OK. 72 00:05:18,180 --> 00:05:24,340 And what we can do is what we kind of did before up here is we check this. 73 00:05:24,750 --> 00:05:28,290 In fact we can call it we can put this to a function or make it reusable. 74 00:05:28,290 --> 00:05:33,530 So we'll call this function phunk set up ads. 75 00:05:33,890 --> 00:05:34,650 Okay. 76 00:05:35,040 --> 00:05:45,390 And we'll just cut this out of here like so pasted here and then will call set up ads and then here 77 00:05:46,440 --> 00:05:56,310 we will say if success sort of adds We don't know if it fails we don't need to because the ads are already 78 00:05:56,310 --> 00:05:56,850 there. 79 00:05:56,880 --> 00:06:00,070 So if it was successful it set up the ad so it's going to go through here do the check. 80 00:06:00,230 --> 00:06:00,930 Hey does it exist. 81 00:06:00,930 --> 00:06:07,290 If so remove these otherwise load the advertisement which is just what we want to do. 82 00:06:07,830 --> 00:06:08,700 Awesome. 83 00:06:09,240 --> 00:06:10,290 Very very cool. 84 00:06:10,290 --> 00:06:12,790 So let's see if it actually works here. 85 00:06:12,790 --> 00:06:14,110 Got all of our logic in place. 86 00:06:14,100 --> 00:06:20,430 It seems like so what we need to do is actually delete the app from the phone and then reinstall it 87 00:06:20,430 --> 00:06:23,430 and run it with the same user and see if it actually works. 88 00:06:23,430 --> 00:06:25,140 So let's do that now. 89 00:06:25,590 --> 00:06:32,350 So I'm going to delete these here if I can get past the 3D touch which it did. 90 00:06:32,430 --> 00:06:33,700 So those are deleted. 91 00:06:33,990 --> 00:06:36,470 So right the users uninstalled your app. 92 00:06:36,920 --> 00:06:39,540 They later decided you know what I miss the app. 93 00:06:39,630 --> 00:06:42,570 I want to install it again but I Wylma in it purchases what do we do. 94 00:06:42,870 --> 00:06:45,620 So let's go ahead and run it on the phone again. 95 00:06:45,690 --> 00:06:47,970 It does not work on the simulator 96 00:06:50,650 --> 00:06:52,150 it's set up self. 97 00:06:52,180 --> 00:06:55,180 Here we go. 98 00:06:55,300 --> 00:06:58,450 Now let's run it and the app is running. 99 00:06:58,700 --> 00:07:01,020 And of course we see advertisements as expected. 100 00:07:01,020 --> 00:07:05,720 And so what should happen is when I press that button at the top right it should prompt me. 101 00:07:05,750 --> 00:07:07,810 And then my ads should go away. 102 00:07:08,000 --> 00:07:13,290 So press the button. 103 00:07:13,470 --> 00:07:20,320 Well that was fast a little bit too fast don't you think so. 104 00:07:20,440 --> 00:07:23,730 So we let's make sure nothing crazy is going on here. 105 00:07:23,770 --> 00:07:25,500 So we clicked restore purchases. 106 00:07:25,540 --> 00:07:31,030 We went to the purchase manager K and we typed restore purchases. 107 00:07:31,040 --> 00:07:32,170 If we can make payments great. 108 00:07:32,180 --> 00:07:34,720 Otherwise uncomplete was false. 109 00:07:34,730 --> 00:07:35,460 OK. 110 00:07:35,810 --> 00:07:40,260 And so uncomplete our code here let's check it out. 111 00:07:42,300 --> 00:07:44,430 If success is true we'll set up the ads. 112 00:07:44,440 --> 00:07:48,030 Well it wasn't true there so we're good there. 113 00:07:48,270 --> 00:07:53,950 And then we went through here to add and restore the completed transactions and went through here restored. 114 00:07:54,060 --> 00:07:54,780 We finished it. 115 00:07:54,780 --> 00:08:01,180 And if the payment product identifier is removed the adds then let's set it to true. 116 00:08:01,260 --> 00:08:03,240 Wow that was fast so it all worked. 117 00:08:03,240 --> 00:08:04,100 That's pretty cool. 118 00:08:04,110 --> 00:08:06,920 I thought it would take a little bit longer but it worked. 119 00:08:06,960 --> 00:08:10,910 It worked without even prompting for a password or anything like that which is really awesome. 120 00:08:10,920 --> 00:08:14,570 Apple knows which device it is under the hood and made it work for us. 121 00:08:14,570 --> 00:08:15,680 So there you have it. 122 00:08:15,690 --> 00:08:19,170 You've now learned how to work with in-app purchases you've learned how to set up your accounts on iTunes 123 00:08:19,170 --> 00:08:22,200 and developer to Apple dotcom how to get your apps to sink to that. 124 00:08:22,200 --> 00:08:26,420 Don't forget to turn on the capabilities on your project. 125 00:08:26,480 --> 00:08:31,280 Clicking the capabilities tab here you learn how to integrate Google AdMob and how to get better at 126 00:08:31,290 --> 00:08:31,810 showing. 127 00:08:31,830 --> 00:08:36,570 And then you learn how to manage your code so when you make that purchase you actually implement the 128 00:08:36,570 --> 00:08:40,980 feature and how to restore the in-app purchases in the case that an app is deleted and then re-installed 129 00:08:41,040 --> 00:08:42,580 a lot of good stuff here. 130 00:08:42,630 --> 00:08:46,170 We're only scratching the surface though and in a purchase purchases you can do a lot more with subscriptions 131 00:08:46,680 --> 00:08:50,050 and non and consumables as well too. 132 00:08:50,250 --> 00:08:51,750 But enough to get you started. 133 00:08:51,750 --> 00:08:52,770 So that's it for now. 134 00:08:52,770 --> 00:08:54,990 Marc price dove slopes dot com. 135 00:08:55,020 --> 00:08:55,800 See you next time.
