Question

I’m trying to reposition my UIBarButtonItem so that it sits with it’s edges against the top and right of the UINavigationBar. I found this accepted answer on how to do this, but I don’t really understand how to code it.

I’ve started by creating a new class called CustomNavBar which inherits from UINavigationBar. I then placed this method in the implementation:

- (void) layoutSubviews
{


}

What I don’t understand is the part in the answer that says

call [super layoutSubviews] and then find and reposition the button's view.

How do I code this? Even a nudge in the right direction would be helpful. Thanks!

Answer 1

Find the button you want to move after you call layoutSubviews because it will be repositioned to where iOS wants it to be every time layoutSubviews is called.

- (void) layoutSubviews
{
    [super layoutSubviews];

    for (UIView *view in self.subviews) {   // Go through all subviews
        if (view == buttonYouWant) {  // Find the button you want
            view.frame = CGRectOffset(view.frame, 0, -5);   // Move it
        }
    }
}
