ios - NSTimer 计时器WithTimeInterval 不调用选择器(Swift)

Question

我尝试了在其他问题中找到的许多方法，并且其中任何一个都有效。我的问题是计时器没有调用选择器

class MyViewController: UIViewController{
    var progressBarTimer = NSTimer()
    @IBOutlet weak var progress_bar: UIProgressView!

    override func viewDidLoad() {
        self.progress_bar.progress = 0
        self.progressBarTimer = NSTimer.scheduledTimerWithTimeInterval(1.0, target: self, selector: #selector(MyViewController.updateProgress(_:)), userInfo: nil, repeats: true)
        //also tried and redefining the updateProgress without timer parameter:
        /*
        *self.progressBarTimer = NSTimer.scheduledTimerWithTimeInterval(1.0, target: self, selector: #selector(MyViewController.updateProgress), userInfo: nil, repeats: true)
        */
    }
    func updateProgress(timer:NSTimer!) {
        progress_bar.progress += 0.1
        if (progress_bar.progress >= 1) {
           progressBarTimer.invalidate()
        }

    }
}

我已经尝试过

progressBarTimer.fire()

它只执行一次 updateProgress 函数。

有人能解释一下吗？我真的很感激

您可以像这样调用您的函数:

    let postes = ["1","2","3"]
    let timer = NSTimer.scheduledTimerWithTimeInterval(0.1, target: self, selector: "playProgressBar:", userInfo: postes, repeats: true)

并且函数必须像这样:

func playProgressBar(timerSender : NSTimer) {

   //Do Somethings

}
