Question

我在UIViewController中创建了UITabbar。然后我添加了一个UIActionSheet但是当动作表出现时，单击按钮“取消”的顶部时，它可以工作，但是当我点击“取消”的底部时，没有响应。我用这段代码添加了动作表：

actionSheetDelete = [[UIActionSheet alloc] initWithTitle:@"Do you want to continue?" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Delete Item(s)" otherButtonTitles:nil];
actionSheetDelete.actionSheetStyle = UIActionSheetStyleBlackOpaque;
[actionSheetDelete showInView:self.view];
[actionSheetDelete release];

当我点击操作表时，我总是在控制台中显示此警报：

Presenting action sheet clipped by its superview. Some controls might not respond to touches. On iPhone try -[UIActionSheet showFromTabBar:] or -[UIActionSheet showFromToolbar:] instead of -[UIActionSheet showInView:].

你有什么建议吗？提前致谢

Answer 1

尝试：

[actionSheetDelete showFromTabBar:self.tabBarController.tabBar];

Answer 2

您可以在UITabBarController的视图中显示它：

actionSheetDelete = [[UIActionSheet alloc] initWithTitle:@"Do you want to continue?" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Delete Item(s)" otherButtonTitles:nil];
actionSheetDelete.actionSheetStyle = UIActionSheetStyleBlackOpaque;
[actionSheetDelete showInView:self.tabBarController.view];
[actionSheetDelete release];

或者，更强大的版本可能是：

[actionSheetDelete showInView:[UIApplication sharedApplication].keyWindow];

Answer 3

您正试图从视图本身显示操作表。考虑到视图中已经有UITabBarController，这是无法做到的。因此，您必须在显示时从标签栏进行设置。这将确保按钮未加载到选项卡栏的视图下方，并允许与选项卡栏关联的所有操作的可用性。

因此，您应该使用

[actionSheetDelete showFromTabBar:];

以便标签栏是操作表显示位置的初始位置希望这有帮助！
