xcode - 如何更改按钮大小？

Question

我不知道如何更改按钮大小。我应该怎么办？谁能告诉我吗？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

你只需要改变

的值

CGRectMake(140, 400, WIDTH_YOU_WANT, HEIGHT_YOU_WANT)

更改字体:

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

将“Arial-MT”更改为您想要的任何系统字体(注意名称，否则会给您带来错误)。
