我的游戏应该在60年代后停止.但我的计时器代码没有任何反应.
var timer = NSTimer() var counter:Int = 60 var labelCounter:SKLabelNode = SKLabelNode()
这是我的GameScene类中的代码:
func startTimer() { timer = NSTimer.scheduledTimerWithTimeInterval(1.0,target: self,selector: Selector("updateTimer:"),userInfo: nil,repeats: true) } func updateTimer(dt:NSTimer) { counter-- if counter == 0 { timer.invalidate() removeCountDownTimerView() } else{ labelCounter.text = "\(counter)" } } func removeCountDownTimerView() { scene.view.paused = true }
感谢您的见解 :-)
解决方法
试试这样的事……
override func viewDidLoad() { super.viewDidLoad() //calling the wait function self.callForWait() } func callForWait(){ //setting the delay time 60secs. let delay = 60 * Double(NSEC_PER_SEC) let time = dispatch_time(disPATCH_TIME_Now,Int64(delay)) dispatch_after(time,dispatch_get_main_queue()) { //call the method which have the steps after delay. self.stepsAfterDelay() } } func stepsAfterDelay(){ //your code after delay takes place here... }
