我有一个UIActionSheet并且我指定了取消按钮，但是当它被点击时它不会被忽略？

I have an UIActionSheet and I am specifying the cancel button however it does not dismiss when its tapped?

UIActionSheet *actionSheet = [[[UIActionSheet alloc]initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Target Complete" otherButtonTitles:nil] autorelease]; [actionSheet showInView:self.view];

根据文档，我不需要任何代码，即使我尝试实现didCancel委托从未调用过的方法？

According to the documentation I don't need any code and even when I try and implement the didCancel delegate method its never called?

推荐答案

您需要在iPhone上的任务栏或工具栏上显示，因为它会剪切一些控件，如果你在视野中使用显示。

You need to display from a taskbar or a toolbar on iPhone as it clips some of the controls if you use display in view.
