swift – tvOS Button Action

let randomBtn = UIButton()
randomBtn.setTitle("Zuf?llig",forState: .Normal)
let RndNormal = UIImage(named: "RndNormal")
let RndHoover = UIImage(named: "RndHoover")
randomBtn.setImage(RndNormal,forState: .Normal)
randomBtn.setImage(RndHoover,forState: .Focused)
randomBtn.setTitleColor(UIColor.blackColor(),forState: .Normal)
randomBtn.setTitleColor(UIColor.whiteColor(),forState: .Focused)

randomBtn.addTarget(self,action: #selector(ViewController.click(_:)),forControlEvents: UIControlEvents.TouchUpInside)

let screenSize: CGRect = UIScreen.mainScreen().bounds
let screenWidth = screenSize.width
randomBtn.frame = CGRect(x: screenWidth - 150,y: 60,width: 70,height: 70)
self.view.addSubview(randomBtn)

但如果按下按钮,动作永远不会被解雇,tvOS有什么不同吗？

func click(sender: UIButton) {
    print("click")
}
