应用内购买不适用于ios7 /从不兼容类型分配给..

我遵循了本教程，它对于ios6似乎运行良好，但是当我尝试使用ios7时，它永远不会调用：

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

（修复了不兼容的类型错误，这要归功于Macro206）（在ios7上仍无法使用应用内购买功能（但在ios6上似乎可以正常使用（可以购买并且广告横幅的Alpha设置为0（在BOOL上设置了Alpha设置））是真实的，来自我应用程序的其他位置））））

这是我所拥有的：（我删除了动画/图形代码以使其更短）

我得到的警告是：

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

我看过类似的问题，但从未真正了解如何解决，添加了（{id）self“而不是仅仅” self“摆脱了错误，但并不能解决问题，代码停在了[[productsRequest start] ;“ 和“-（void）productsRequest：”永远不会被解雇。

我确定我在犯基本错误=（

（哦，以防万一，我已经在模拟器中对其进行了测试，在ios6上可以正常工作，但在ios7上不能正常工作）
