Swift：转换SKSpriteNode

Question

我试图为UIView实现此代码，但是对于SKSprite节点：

stopIcon.transform = CGAffineTransformMakeScale(0.01, 0.01)

UIView.animateWithDuration(0.5, animations: { () -> Void in
        self.stopIcon.transform = CGAffineTransformMakeScale(1.0, 1.0)
        })

我的SKSprite节点设置如下：

stopIcon = SKSpriteNode(imageNamed: "StopIcon")
    stopIcon?.size = CGSize(width: ((stopImage?.size.width)! * 0.75), height: ((stopImage?.size.height)! * 0.75))
    stopIcon?.position = CGPoint(x: self.size.width * 0.22, y: self.size.height * 0.91)
    self.addChild(stopIcon!)

谢谢大家。

我猜你想在0.5秒内缩放SKSpriteNode，从0.1 - > 1.0（满刻度的十分之一）。

使用SpriteKit的SKAction类可以这样实现：

//set the inital scale of node to 0.1
stopIcon.setScale(0.1)
//create action to scale skspritenode to scale of 1.0 over 0.5 seconds.
let scaleAction = SKAction.scaleTo(1.0, duration: 0.5)
//call on the action.
stopIcon.runAction(scaleAction)
