How to hide status bar of a single view controller in iOS 9?

Question

In a ViewController, which I presented modally, I did this:

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

This used

Answer 1

A late answer but if you need an alternative solution you can use this:

public func ShowStatusBar() {

    let statusBarWindow = UIApplication.shared.value(forKey: "statusBarWindow") as? UIWindow
    UIView.animate(withDuration: 0.3) {
        statusBarWindow?.alpha = 1
    }
}

public func HideStatusBar() {

    let statusBarWindow = UIApplication.shared.value(forKey: "statusBarWindow") as? UIWindow
    UIView.animate(withDuration: 0.3) {
        statusBarWindow?.alpha = 0
    }
}

Answer 2

In iOS 9, Xcode 7, Swift 2.0, it's back to how it was previously.

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

In fact Xcode will tell you that

UIApplication.sharedApplication().setStatusBarHidden(true, withAnimation: .None) 

has been deprecated and that you should use the prefersStatusBarHidden method.

Answer 3

You can achieve this by simply overriding prefersStatusBarHidden property in your ViewController as shown below :

override var prefersStatusBarHidden: Bool {
   return true
}

This works for Swift 3/4.

Answer 4

When all else fails (as it did for me)

Answer 5

UIApplication.sharedApplication().setStatusBarHidden(true, withAnimation: .None) 

and when you want it back in a separate VC:

UIApplication.sharedApplication().setStatusBarHidden(false, withAnimation: .None) 

Answer 6

For Swift 3 & Swift 4 it has changed to overriding a variable like this:

override var prefersStatusBarHidden: Bool {
  return true
}

If you want to "Update" the state once the view controller is already being displayed, you will need to call:

setNeedsStatusBarAppearanceUpdate()

Please refer to the documentation.
