如何设置以编程方式将uibutton对齐到右边？

Question

就像显示的图像一样.如何将按钮对齐？CGRectMake似乎只根据浮点x,y创建框架,它来自左上角.谢谢你的帮助.

Answer 1

x原点取决于superview的宽度(在我的示例中为self.view)

#define RIGHT_MARGIN 20

myButton.frame = CGRectMake(self.view.frame.size.width - myButton.frame.size.width - RIGHT_MARGIN, yValue, myButton.frame.size.width, myButton.frame.size.height)
