xcode 7个带限制的定时器

Question

我已经制作了一个带有计时器的应用程序，但现在我希望计时器在一段时间后停止，例如 10 秒后。当计时器结束时，它会转到下一个视图控制器。如果有人能帮助我，我会很高兴。先感谢您。这是我已有的代码：

导入 UIKit

class Level1: UIViewController {

var timerCount = 0
var timmerRunning = false
var timer = NSTimer()



@IBOutlet weak var timerLabel: UILabel!

func Counting() {
  timerCount += 1
    timerLabel.text = "\(timerCount)"

}


@IBAction func startButton(sender: UIButton) {

    if timmerRunning == false{
        self.timer = NSTimer.scheduledTimerWithTimeInterval(1, target: self, selector: Selector("Counting"), userInfo: nil, repeats: true)
                 self.timmerRunning = true
    }

}



@IBAction func stopButton(sender: UIButton) {


    if timmerRunning == true{

        self.timer.invalidate()
           self.timmerRunning = false
    }

}

@IBAction func restartButton(sender: UIButton) {

    timerCount = 0
    timerLabel.text = "0"

}





override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

}

试试这个：

func Counting() {
      timerCount += 1
        timerLabel.text = "\(timerCount)"

    if timerCount == 10 {
        self.timer.invalidate()
        //go to the next view controller, you'll need to create a navigation controller if you don't have one
        navigaionController.pushViewController(someViewController, animated:false)
        }
