UIStatusBar won't disappear

Question

I've tried to create a class in Swift, which autohides my UIStatusBar and my navigationController after 1 Second. My problem is, that the StatusBar is not going to disappear. This is what I got:

override func viewDidLoad() {
    super.viewDidLoad()
    NSTimer.scheduledTimerWithTimeInterval(1.0, target: self, selector: "prefersStatusBarHidden", userInfo: nil, repeats: false)
}
override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)
    }

override func preferredStatusBarUpdateAnimation() -> UIStatusBarAnimation {
    return UIStatusBarAnimation.Fade
}

override func prefersStatusBarHidden() -> Bool {
    if (barcounter == 0){
        hide()
        barcounter = 1
        return true
    }
    else {
        show()
        barcounter = 0
        return false
    }
}

@IBAction func picturePressed(sender: AnyObject) {
    prefersStatusBarHidden()
}

func hide(){

    UIView.animateWithDuration(1, delay: 1, options: UIViewAnimationOptions.CurveEaseOut, animations: {

        self.navigationController?.navigationBar.alpha = 0.0

        }, completion: nil)

}

func show(){
    UIView.animateWithDuration(1, delay: 1, options: UIViewAnimationOptions.CurveEaseOut, animations: {

        self.navigationController?.navigationBar.alpha = 1.0

        }, completion: nil)

}

Answer 1

You need to override this method in whichever view controller u want to hide uistatusbar.

override func prefersStatusBarHidden() -> Bool {
    return true;
}

if its not work then try this:-

In Info.plist set View controller-based status bar appearance to NO

And call UIApplication.sharedApplication().statusBarHidden = true

hope this helps you.
