[objc] frame, layout, CGRect, 레이아웃 재정의

     

UIView *a = ...

        CGRect target = a.frame;

        a.frame = CGRectMake(target.origin.x, target.origin.y, target.size.width, target.size.height);

간단히..

CGRect target = a.frame;

target.origin.x = 0;

target.size.width = 100;

a.frame = target;
