SKAction.runBlock 顺序运行出现问题

Question

我有几个 runBlocks 我需要按顺序运行，但即使使用 SKAction.sequence([action1, action2, action3]) 时它们仍然同时运行。任何帮助将不胜感激。

这是我的代码示例：

func SetupText() {

    let wait = SKAction.waitForDuration(2.0)

    var Label1 = SKLabelNode()
    Label1.fontColor = UIColor.whiteColor()
    Label1.position = CGPointMake(self.size.width / 2.3, self.size.height / 1.4)
    Label1.text = "blah1"
    self.addChild(Label1)
    scrollLabel1 = SKAction.runBlock({
        self.runSomeCode(Label1)
    })

    var Label2 = SKLabelNode()
    Label2.fontColor = UIColor.whiteColor()
    Label2.position = CGPointMake(self.size.width / 2.5, self.size.height * 0.6)
    Label2.text = "blah2"
    self.addChild(Label2)
    scrollLabel2 = SKAction.runBlock({
        self.runSomeCode(Label2)
    })

    var Label3 = SKLabelNode()
    Label3.fontColor = UIColor.whiteColor()
    Label3.position = CGPointMake(self.size.width / 2.5, self.size.height * 0.5)
    Label3.text = "blah3"
    self.addChild(Label3)
    scrollLabel3 = SKAction.runBlock({
        self.runSomeCode(Label3)
    })

    var Label4 = SKLabelNode()
    Label4.fontColor = UIColor.whiteColor()
    Label4.position = CGPointMake(self.size.width / 2.5, self.size.height * 0.4)
    Label4.text = "blah4"
    self.addChild(Label4)
    scrollLabel4 = SKAction.runBlock({
        self.runSomeCode(Label4)
    })

    var Label5 = SKLabelNode()
    Label5.fontSize = 20
    Label5.fontName = "LiquidCrystal-Regular"
    Label5.fontColor = UIColor.whiteColor()
    Label5.position = CGPointMake(self.size.width / 2.5, self.size.height * 0.3)
    Label5.text = "blah5"
    self.addChild(Label5)
    scrollLabel5 = SKAction.runBlock({
        self.runSomeCode(Label5)
    })

    var actions = Array<SKAction>()
    actions.append(wait)
    actions.append(scrollLabel1)
    actions.append(scrollLabel2)
    actions.append(scrollLabel3)
    actions.append(scrollLabel4)
    actions.append(scrollLabel5)
    let sequence = SKAction.sequence(actions)

    self.runAction(sequence)

}

实际上似乎与动作无关，但它与运行块有关。运行块的操作可能比序列花费更长的时间，这意味着您的序列看起来是并发的。使用常规操作而不是操作块需要解决您的问题。
