Sometimes I am a little irrated by making the statusbar white in iOS development. It looks simple. But, the way to do it is a little complicated.
How to make your status bar style white in iOS9
Put the code below into your controller file or AppDelegate file.
self.navigationController?.navigationBar.barStyle = UIBarStyle.Black
When you type it, you might get serveral options for UIBarStyle. But BlackOpaque and BlackTranslucent were deprecated. So don’t be hesitated to choose one of them. If you want to make your statusbar white, choose UIBarStyle.Black. That’s simple.
