ios - 应用内购买不适用于 ios7/从不兼容的类型分配给..

Question

我关注了this tutorial它似乎适用于 ios6，但当我尝试使用 ios7 时，它从不调用:

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)

(修复了不兼容的类型错误，感谢 Macro206)(应用内购买在 ios7 上仍然不起作用(但似乎在 ios6 上运行良好(能够购买并且广告横幅的 alpha 设置为 0(当 BOOL 为真时设置 alpha，从我的应用程序的其他地方))) )

这是我的:(我删除了动画/图形代码以使其更短)

我收到的警告是:

(At line: @implementation MainMenu)
Method definition for 'tapsRemoveAdsButton' not found
Method definition for 'purchase' not found

我看过类似的问题，但从来没有真正理解如何解决它，添加“(id)self”而不只是“self”消除了错误，但它没有解决问题，代码停在“[产品请求开始];"和“- (void)productsRequest:”永远不会被解雇。

我确定我犯了基本错误 =(

(哦，以防万一，我一直在模拟器中测试它，在 ios6 上运行良好但在 ios7 上运行不正常)

就像提到的 Macro206 你必须添加 <SKProductsRequestDelegate>在你的@interface 和 #import <StoreKit/StoreKit.h> 之后.此外，应用内购买应在具有特殊测试帐户的真实设备上进行测试。

您的代码格式非常糟糕，并且保留了过时的代码行。如果你想让人们审查你的代码，你应该让他们更容易阅读。看看this link
