Swift-创建UIButton(其他UI组件雷同)

     let button = UIButton.init(frame: CGRectMake(100, 100, 100, 100))
        button.setTitle("按钮", forState: UIControlState.Normal)
        button.backgroundColor = UIColor.redColor()
        button.addTarget(self, action:#selector(buttonClick), forControlEvents: UIControlEvents.TouchUpInside)
        button.setTitleColor(UIColor.grayColor(), forState: UIControlState.Normal)
        self.view.addSubview(button)

    //点击事件
    func buttonClick(){
          print("点击")
      }
