UIActionSheet cancel button strange behaviour

Instead of passing the current view controller's view to the action sheet, use the showFromTabBar: method of UIActionSheet.

The Right Way
This will give the correct tappable area:

[actionSheet showFromTabBar:self.tabBarController.tabBar];

The Wrong Way
This will put the tappable area in the wrong place (if you're using a tab bar or toolbar):

[actionSheet showInView:self.view];

If you're using a toolbar, use the showFromToolbar: method instead. You'll need a reference to the toolbar, most likely an ivar

[actionSheet showFromToolbar:self.myToolbar];

My Old Answer Also works, but is hacky:

Just found a possible answer:

01-Dec-2008 10:22 PM Tom Saxton: I looked at this bug some more, and it seems to be an issue with the tabbar.

If you call UIActionSheet's [sheet showInView:self.view] from a view controller that is a child of a UITabViewController, then the hit testing on the cancel button fails in that portion of the UIActionSheet that lies above the tabbar's view.

If you instead pass in the UITabBarController's view, then the UIActionSheet acts as expected.

NOTE: in iPhone OS 2.1 and earlier, the UIActionSheet came up from the top of the tab bar when you pass the child view, but in 2.2, it comes up from the bottom of the tab bar, and thus covers the tab view.

Edit: It works correctly when I change the view to be the tab bar's view

[sheet showInView:self.parentViewController.tabBarController.view];

I found an answer over here that works.

using: [filterActionSheet showInView:[self.view window]];

i tried a few ways to get to my tab bar and they way this app is set up it seem convoluted...

Instead use:

[sheet showFromTabBar:theTabBar];

Here is the fix.Try this:

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

I think a combination of three of the answers is the right way of handling this:

    [actionSheet showFromTabBar:self.tabBarController.tabBar];

i.e., use showFromTabBar (that's why it exists) and you don't need the parentViewController as Nathan pointed out (in fact, self.parentViewController.tabBarController.tabBar returns nil for me.
