activityIndicators und UIApplication.sharedApplication()

Question

Berufung Unlock-Gerät funktioniert nicht druckt „unlockCalled“ eine Menge Zeit und gibt dann diesen Fehler:

2016-03-27 14:20:45.976 xxx[1002:57886] -[UIApplication endIgnoringInteractionEvents] called without matching -beginIgnoringInteractionEvents. Ignoring. 

Wohin gehe ich falsch?

var activityIndicator = UIActivityIndicatorView() 

func lockDevice(){print("lockCalled") 
    activityIndicator = UIActivityIndicatorView(frame: self.view.frame) 
    activityIndicator.backgroundColor = UIColor(white: 1.0, alpha: 0.5) 
    activityIndicator.center = self.view.center 
    activityIndicator.hidesWhenStopped = true 
    activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.Gray 
    view.addSubview(activityIndicator) 
    activityIndicator.startAnimating() 
    UIApplication.sharedApplication().beginIgnoringInteractionEvents() 
} 
func unlockDevice(){ 
    print("unlockCalled") 
    activityIndicator.stopAnimating() 
    UIApplication.sharedApplication().endIgnoringInteractionEvents() 
}

Dank @Alladinian

dispatch_async(dispatch_get_main_queue(), {() -> Void in 
    self.unlockDevice() 
})
