ios - 继承 UIActionSheet

我想继承 UIActionSheet 以便我可以添加 block API。

我想子类化，这样我仍然可以享受操作表的“ self 保留”行为。
我更喜欢它而不是创建一个将 UIActionSheet 作为实例保存的对象，因为那样我将需要保存对该对象的引用，因此它不会被释放。

所以我的问题是，我可以继承 UIActionSheet(Apple 会允许吗)？

我只是不确定，因为我在 UIActionSheet 类引用中看到:

Subclassing Notes:
UIActionSheet is not designed to be subclassed, nor should you add views to its hierarchy. If you need to present a sheet with more customization than provided by the UIActionSheet API, you can create your own and present it modally with presentViewController:animated:completion:.

Best Answer-推荐答案

答案是否定的。如果您将 UIActionSheet 子类化，您的应用程序在发送到 Apple App Store 时可能会被拒绝。如果 UIActionSheet 不能满足您的需求，您需要实现自己的自定义操作表。这同样适用于 UIAlertView。

这显然是 stated in the documentation :

UIActionSheet is not designed to be subclassed, nor should you add views to its hierarchy. If you need to present a sheet with more customization than provided by the UIActionSheet API, you can create your own and present it modally with presentViewController:animated:completion:.
