UIBarButtonItem with UIButton as CustomView - from UIButton, how to access the UIBarButtonItem its in?

Question

I have a UIBarButtonItem with UIButton as custom view.

The UIButton has a addTarget:action: on it. In the action

Answer 1

Let's say you have added the UIButton aButton to UIBarButtonItem info_Button as following:

//Add a button on top of the UIBarButtonItem info_button
UIButton *aButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
[aButton addTarget:self action:@selector(showInfo:) forControlEvents:UIControlEventTouchUpInside];
info_Button.customView = aButton;

Now, in showInfo, presentPopoverFromBarButtonItem:info_Button(instead of presentPopoverFromBarButtonItem:sender), this will pass the UIBarButtonItem info_button to make pop over works:

- (IBAction)showInfo:(id)sender
{   
    [self.flipsidePopoverController presentPopoverFromBarButtonItem:info_Button   permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

}
