iOS IAP教程

1. 创建应用

首先进入iTunes Connect然后按下 Manage Your Applications

接下来按下Add New Applicationbutton创建应用

2. 在应用中创建IAP

创建应用之后，在Manage Your Applications中点应用的图示，进入应用

就会看到上图画面点击Manage In App Purchases就能够进入IAP的管理画面

在这边要注意左边的Bundle ID，在Xcode项目中，info.plist中的设定需与此Bundle同样

(此Bundle ID会在创建应用时填入)

此为IAP的管理画面，仅仅要按下Create Newbutton就可创建IAP

在本图中我已经创建好三个IAP

而当中要注意的是Product ID，仅仅要用Product ID就能够请求IAP的相关讯息及交易

Consumable

消耗品，每次下载都需付费

Non-Consumable

一次性付费，通经常使用在升级pro版或是移除广告等

Auto-Renewable Subscriptions

自己主动更新订阅

Free Subscription

免费订阅

Non-Renewing Subscription

非自己主动更新订阅

3. 怎样创建沙盒測试用户

进入iTunes Connect，点击Manage Users

在这个画面中点下Test User

按下Add New User就能够了，Email Address就是登入沙盒測试的username

password的部份在Add New User时可自行创建

因为交易是永久有效的，建议addTransactionObserver这个于应用启动后即可监听，而不要在用户想买东西时才监听

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

交易结果会于此处显示

苹果准备沙盒測试环境需一段时间，若是创建IAP后能够取得资讯，却无法交易成功，要稍待一下

另外若是模拟器能够购买，但真机购买却失败的话，做Hard Reset就能够了，一直按住Home键跟电源键就能够做Hard Reset

按住后会出现关机画面，不要理会它，继续等，直到等到白苹果出现后，就能够放开等它重开机完成后再測试
