iOS IAP教程

1. 建立應用

首先進入iTunes Connect然後按下 Manage Your Applications

接下來按下Add New Application按鈕建立應用

2. 在應用中建立IAP

建立應用之後，在Manage Your Applications中點應用的圖示，進入應用

就會看到畫面點擊Manage In App Purchases就可以進入IAP的管理畫面

在這邊要注意左邊的Bundle ID，在Xcode項目中，info.plist中的設定需與此Bundle相同

(此Bundle ID會在建立應用時填入)

此為IAP的管理畫面，只要按下Create New按鈕就可建立IAP

在本圖中我已經建立好三個IAP

而其中要注意的是Product ID，只要用Product ID就可以請求IAP的相關訊息及交易

Consumable

消耗品，每次下載都需付費

Non-Consumable

一次性付費，通常用在升級pro版或是移除廣告等

Auto-Renewable Subscriptions

自動更新訂閱

Free Subscription

免費訂閱

Non-Renewing Subscription

非自動更新訂閱

3. 如何建立沙箱測試使用者

進入iTunes Connect，點擊Manage Users

在這個畫面中點下Test User

按下Add New User就可以了，Email Address就是登入沙箱測試的使用者名稱

密碼的部份在Add New User時可自行建立

4.代碼

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];

由於交易是永久有效，建議addTransactionObserver這個於應用啟動後就行監聽，而不要在使用者想買東西時才監聽

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions

交易結果會於此處顯示

蘋果準備沙箱測試環境需一段時間，若是建立IAP後可以取得資訊，卻無法交易成功，要稍待一下

另外若是模擬器可以購買，但真機購買卻失敗的話，做Hard Reset就可以了，一直按住Home鍵跟電源鍵就可以做Hard Reset

按住後會出現關機畫面，不要理會它，繼續等，直到等到白蘋果出現後，就可以放開等它重開機完畢後再測試
