Button bar height?

Button bar height?

And centering the cancel button would be nice too (as well as changing it's color). Tried some things but nothing worked..

        [cancelButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
        [cancelButton setTintColor:[UIColor whiteColor]];

        cancelButton.translatesAutoresizingMaskIntoConstraints = YES;

        cancelButton.center = CGPointMake(infoButton.frame.origin.x, infoButton.frame.origin.y);
        cancelButton.frame = CGRectMake(infoButton.frame.origin.x, infoButton.frame.origin.y, cancelButton.frame.size.width, cancelButton.frame.size.height);
     //   cancelButton.center = [[[[self.scanReader.view.subviews objectAtIndex:2] subviews] objectAtIndex:0] center];

        [[[[self.scanReader.view.subviews objectAtIndex:2] subviews] objectAtIndex:0] setNeedsDisplay];
