记住在iOS中（而不是在iOS中）对你的属性采用大写的态度是不对的。

我不想再因数所有的代码，我会尽量保持你的结构和方法可能：

buttoneOne = UIButton(frame: CGRect(x: 0, y: 0, width: frame.size.width/25, height: frame.size.height/20)) 
buttoneOne.center = CGPoint(x: view.frame.size.width/6.5, y: view.frame.size.height/2) 
buttoneOne.setImage(ButtonTextureOne, forState: .Normal) 
buttoneOne.addTarget(self, action: #selector(Play.PlayesrOne), forControlEvents: UIControlEvents.TouchUpInside) 
self.view?.addSubview(buttoneOne) 

func makePlayerOne() { 
    if (self.childNodeWithName("playerOne") == nil) { 
     playerOne = SKSpriteNode(imageNamed: "PlayerOne") 
     playerOne.size = CGSize(width: 150, height: 200) 
     playerOne.position = CGPoint(x: frame.size.width/2, y: frame.size.height/2) 
     playerOne.zPosition = -1 
     playerOne.name = "playerOne" 
     self.addChild(playerOne) 
    } 
} 

func PlayesrOne() { 
    player.removeFromParent() 
    playerOne.removeFromParent() 
    playerTwo.removeFromParent() 
    makePlayerOne() 
}

你可以做同样的事情player2重生..
