UIBarButtonItem: target-action not working?

Question

Hey fellas,

I've got a custom view inside of a UIBarButtonItem, set by calling -initWithCustomView.

OK, so the view renders fine, but when I tap it, it doesn't call the method that I set as the UIBarButtonItem's action property.

Oh, and I have verified that my -deselectAll method works fine.

Keep in mind that I am not using Interface Builder and I am sure that the method signature is correct

Here's my code:

 UIImageView *SOCImageView = [[ UIImageView alloc ] initWithImage:[ UIImage imageNamed: @"cancel_wide.png" ] ];
 SOItem.leftBarButtonItem = [[ UIBarButtonItem alloc ] initWithCustomView: SOCImageView ];
 [ SOCImageView release ];
 [ SOItem.leftBarButtonItem setTarget: self ];
 [ SOItem.leftBarButtonItem setAction: @selector( deselectAll ) ];

Thanks a million

Answer 1

Jacob, everything looks good, however you may not have provided the correct selector.

Can you verify that your action is actually declared

- (void) deselectAll;

and not

- (void) deselectAll:(id)sender;

If it's the latter, you will need to set the action to @selector(deselectAll:). (note the semi-colon to match the method declaration)

Also, void might be IBAction, but that's not relevant to this problem you're having.

Answer 2

Is your custom view eating touch events or passing them on to parent view?

I do not think the target and action of the UIBarButtonItem apply to custom views. Try using a UIButton instead of UIImageView and applying the target and action to the button.
