this give the size of the UIButton

  NSLog(@"%f",button.frame.origin.x);
  NSLog(@"%f",button.frame.origin.y);

How get the center of origin frame of the UIButton?? any help is appreciated

Answer 1

 CGPoint centerPoint = [button center];

Answer 2

NSLog(@"%f",button.frame.origin.x);
NSLog(@"%f",button.frame.origin.y);

不，这不会给你大小，它会给你按钮的 x 和 y 位置，按钮大小是：

NSLog(@"%f",button.frame.size.width);
NSLog(@"%f",button.frame.size.height);

你可以得到你的按钮的中心，比如：

CGPoint center = [button center];
