Obj-C，为什么我的 UIActionSheet 取消按钮很难点击？
我注意到在我的应用程序中，我的取消按钮很难点击，似乎点击区域不在中心。
我该如何解决这个问题？
这是我的代码...
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@""
delegate:dg
cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil
otherButtonTitles: @"Help Pages", @"Tutorial",
@"Feedback / Questions ", @"Facebook Group", @"About", nil];
actionSheet.actionSheetStyle = UIActionSheetStyleBlackOpaque;
[actionSheet setTag:CommonUIActionSheetHelp];
[actionSheet showInView:vw];
[actionSheet release];
I've noticed in my app that my cancel button is hard to tap, it seem like the hit area is not in the center.
How do I fix this ?
Heres my code...
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@""
delegate:dg
cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil
otherButtonTitles: @"Help Pages", @"Tutorial",
@"Feedback / Questions ", @"Facebook Group", @"About", nil];
actionSheet.actionSheetStyle = UIActionSheetStyleBlackOpaque;
[actionSheet setTag:CommonUIActionSheetHelp];
[actionSheet showInView:vw];
[actionSheet release];

我认为你的问题出在
[actionSheet showInView:vw];上，也许你在应用程序中使用 tabBarController/toolBar（在底部），此时就会发生此错误。您应该根据您的设计使用
showFromToolbar或showFromTabBar。如果您的设计不同，请注明。（如果那里没有 tabBar/toolBar）。谢谢
I think your problem lies in the
[actionSheet showInView:vw];, perhaps you are using tabBarController/toolBar in you application(at bottom), this error occurs at that time.you should use either
showFromToolbarorshowFromTabBaras per your design. If your design is different then please mention it.(if no tabBar/toolBar there).Thanks

我在 iOS 8 中遇到类似的问题，使用带有
UIAlertControllerStyleActionSheet样式的UIAlertController。问题是操作表上的第一次点击被忽略。
事实证明，这与我的文本字段的键盘干扰触摸有关。
解决方法是先关闭键盘，然后显示操作表。
I have similar problem in iOS 8, using
UIAlertControllerwith styleUIAlertControllerStyleActionSheet.The problem is that the first tap on the action sheet is ignored.
Turned out it got to do with my text field's keyboard interfering with the touches.
The fix is to dismiss the keyboard first, then present the action sheet.
