配置Developer.apple.com

登录到Developer.apple.com，然后进行以下步骤：

为应用建立建立一个不带通配符的App ID

用该App ID生成和安装相应的Provisioning Profile文件。

配置iTunes Connect

登录到iTunes Connet，然后进行以下步骤：

1.用该App ID创建一个新的应用。

2.在该应用中，创建应用内付费项目，选择付费类型，通常可选的是可重复消费(Consumable)的或是永久有效(Non-Consumable)的2 种，然后设置好价格和Product ID以及购买介绍和截图即可，这里的Product ID是需要记住的，后面开发的时候需要。

1、 在工程中引入 storekit.framework 和 #import

2、 获得所有的付费Product ID列表。这个可以用常量存储在本地，也可以由自己的服务器返回。

//根据付费Product ID去请求

遵守<SKProductsRequestDelegate,SKPaymentTransactionObserver>

-(void)viewDidload{

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];

}

} else {
