如何更改按钮大小？

Question

我不知道如何更改按钮大小。我该怎么办？有人能告诉我吗？这是我的代码：

   let playAgain: UIButton = UIButton(frame: CGRectMake(140, 400, 100, 50))
   playAgain.setTitle("Play Again", forState: UIControlState.Normal)


   playAgain.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside)
   playAgain.tag = 1
   self.view!.addSubview(playAgain)

Answer 1

您只需更改

的值即可

CGRectMake(140, 400, WIDTH_YOU_WANT, HEIGHT_YOU_WANT)

更改字体：

playAgain.titleLabel!.font = UIFont(name: "Arial-MT", size: 20)

改变＆＃34; Arial-MT＆＃34;对于你想要的任何系统字体（注意名称或它会给你一个错误）。
