There was a problem hiding this comment. Should do if (self.superview != nil) {

There was a problem hiding this comment. Can make this more debug friendly by doing: CGFloat superviewWidth = CGRectGetWidth(self.superview.bounds);
BOOL diameterLessThatSuperviewWidth = self.diameter < superviewWidth;
self.offsetToCenter = diameterLessThatSuperviewWidth ? (superviewWidth - self.diameter) / 2 : 0; |
