UIActionSheet cancel button not dismissing actions

问题:

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];

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

Try this

[actionSheet showInView:[self.view window]];

This Will do the trick

[actionSheet showInView:[self.view window]];

instead of

[actionSheet showInView:self.view];

回答3:

use

[actionSheet showFromTabBar:[[self tabBarController] tabBar]];

instead of

[actionSheet showInView:self.view];

this is working fine.. :-)

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.
