停止正在运行的SKAction - Sprite Kit

The following code will animate a rotation.

以下代码将为旋转设置动画。

let something:SKSpriteNode = SKSpriteNode()

func start(){
  let rotateAction = SKAction.rotateToAngle(CGFloat(M_PI), duration: 10.0)
  something.runAction(SKAction.sequence([rotateAction]))
}

Now I want to stop the animation within the animating duration. Is there anything similar to the following? I want to stop the animation when the user touches the screen.

现在我想在动画持续时间内停止动画。有什么类似的以下内容吗？我想在用户触摸屏幕时停止动画。

func stop(){
  something.SKAction.stop()
}

You just have to use either:

你只需要使用：

something.paused = false // or true to pause actions on the node
something.paused = false //或true表示暂停节点上的操作
something.removeAllActions() to definitely remove actions associated to the node
something.removeAllActions（）肯定删除与节点关联的操作
name your action when launching something.runAction(action,withKey:"action1") and then something.removeActionForKey("action1") to remove a given action
在启动something.runAction（action，withKey：“action1”）然后something.removeActionForKey（“action1”）删除给定的动作时命名你的动作

You may also change the speed if needed.

如果需要，您也可以更改速度。

Firstly, run the action with a key so you can identify it later:

首先，使用密钥运行操作，以便稍后识别：

something.runAction(rotateAction, withKey: "rotate action")

Then you can stop it later by calling

然后你可以通过打电话来阻止它

something.removeActionForKey("rotate action")

Alternatively, you can remove all actions also

或者，您也可以删除所有操作

something.removeAllActions()
