如何以编程方式将UISwitch放入SpriteKit / Skcene中

Question

我只是试图将已经在Xcode中构建的默认开关放在sKcene中。我需要知道如何在swift中执行此操作，或者是否可以谢谢。

Answer 1

是的，这是可能的。只需在SKScene类中使用此代码：

override func didMoveToView(view: SKView) {
    /* Setup your scene here */
    let switchDemo = UISwitch(frame:CGRectMake(150, 300, 0, 0))
    switchDemo.on = true
    switchDemo.setOn(true, animated: false)
    switchDemo.addTarget(self, action: "switchValueDidChange:", forControlEvents: .ValueChanged)
    self.view!.addSubview(switchDemo)
}

帮助方法：

func switchValueDidChange(sender:UISwitch!)
{
    if (sender.on == true){
        print("on")
    }
    else{
        print("off")
    }
}

结果：

Answer 2

// Set the desired frame  of switch here

let onOffSwitch:UISwitch = UISwitch(frame:CGRectMake(2, 2, 30, 30))

//assign an action 
onOffSwitch.addTarget(self, action: "onOffSwitchTapped:", forControlEvents: UIControlEvents.ValueChanged)

//Add in required view
self.view.addSubview(onOffSwitch)

Answer 3

已更新为快速5

override func didMoveToView(view: SKView) {
    /* Setup your scene here */
    let switchDemo = UISwitch(frame:CGRect(x: 150, y: 300, width: 0, height: 0))
    switchDemo.isOn = true
    switchDemo.setOn(true, animated: false)
    switchDemo.addTarget(self, action: #selector(switchValueDidChange(_:)), for: .valueChanged)
    self.view!.addSubview(switchDemo)
}

Helper方法：

@objc func switchValueDidChange(_ sender: UISwitch!) {
    if (sender.isOn == true){
        print("on")
    }
    else{
        print("off")
    }
}
