程序内采购不工作于ios7 /分配给..。从不相容类型

Question

我跟踪了本教程，它似乎在ios6中运行得很好，但是当我尝试使用ios7时，它从不调用：

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

(修复了不兼容的类型错误，多亏了Macro206) (应用程序中的采购仍然不能在ios7上工作(但在ios6(能够购买，广告横幅的alpha设置为0(当BOOL为真时，从我的应用程序中设置))工作得很好)

以下是我所拥有的：(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，但从未真正理解如何修复它，添加了"(id)self“而不是仅仅"self”- -消除了错误，但它没有解决问题，代码在"productsRequest start;“和”- (void)productsRequest:“从不被解雇时停止。

我确信我做的是基本错误=

(哦，万一有关系，我一直在模拟器上测试它，在ios6上工作得很好，在ios7上就不行了)

正如Macro206提到的，您必须在@接口和#import <StoreKit/StoreKit.h>之后添加<SKProductsRequestDelegate>。此外，在应用程序购买应该在一个真正的设备上测试一个特殊的测试帐户.

您的代码被格式化得很糟糕，并且保留了过时的行。如果你想让人们检查你的代码，你应该让他们更容易读懂。看看此链接
