iphone - iOS 5 中的方法调配？

Question

Apple 是否在 iOS 5 中阻止了 Method Swizzling？

我做了一些尝试，发现一个带有 Method Swizzling 的应用程序可以在 iOS 4 上运行，但不能在 iOS 5 上运行。

注意:该应用程序适用于 iOS 5，但不适用于使用 Method Swizzling 的部分。

Answer 1

Apple 不久前向一些被发现在 App Store 应用程序中使用 method swizzling 的开发者发送了一封电子邮件:

Your application, xxx, currently posted to the App Store is using method_exchangeImplementations to exchange the implementation of Apple provided APIs with your own implementations. Because of upcoming changes, this behavior in your application may cause a crash or cause user data loss on iPhone OS 4.0.

xxx uses method_exchangeImplementations to exchange the implementation of dealloc with your method ttdealloc. It also exchanges the implementation of the method popViewControllerAnimated: with your method popViewControllerAnimated2:.

Please resolve this issue immediately and upload your new binary to iTunes Connect. We may remove your application if we believe that doing so is prudent or necessary.

看起来他们想摆脱它，所以我想说他们现在完全阻止它的可能性很高。
