how do you override setFrame for a UILabel

Question

I wanted to override setframe so that it centers the label as well, however doing something like:

- (void)setFrame:(CGRect)frame 
{
    [self setFrame:frame};
    self.center = CGPointMake(self.superview.center.x, kNavigationBarFrameHeight/2);
}

gives me an infinite loop. So how do I do this?

Answer 1

You need to call [super setFrame:frame].

That will call UILabel's implementation of setFrame and not your own. That is what is causing your infinite loop.
