swift - 如何更改按钮的文字大小？

我需要更改文本的大小。我该怎么做？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)

最佳答案

为按钮设置titleLabel.font属性。

playAgain.titleLabel!.font =  UIFont(name: "Helvetica", size: 20)
