try to hide the status bar from a modal view.

already check several methods:

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

with / without self.setNeedsStatusBarAppearanceUpdate()

```

also

```
UIApplication.sharedApplication().setStatusBarHidden(true, withAnimation: .Fade)

```

but depreciated in iOS 9

this works in fullscreen presentation (modal segue presentation option) but note in over full screen which is my setting.

if you have any idea..
