UIStatusBarStyle in iOS 7

• The status bar in iOS 7 is transparent, the view behind it shows through.

• The style of the status bar refers to the appearances of its content. In iOS 7, the status bar content is either dark (UIStatusBarStyleDefault) or light (UIStatusBarStyleLightContent). Both UIStatusBarStyleBlackTranslucent and UIStatusBarStyleBlackOpaque are deprecated in iOS 7.0. Use UIStatusBarStyleLightContent instead.

How to change UIStatusBarStyle

• If below the status bar is a navigation bar, the status bar style will be adjusted to match the navigation bar style (UINavigationBar.barStyle):

// the space between the image and text
CGFloat spacing = 6.0;

// lower the text and push it left so it appears centered 
//  below the image
CGSize imageSize = button.imageView.image.size;
button.titleEdgeInsets = UIEdgeInsetsMake(
  0.0, - imageSize.width, - (imageSize.height + spacing), 0.0);

// raise the image and push it right so it appears centered

// The trick is to link the DeviceSupport folder from the beta to the stable version.

ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/10.1\ \(14B54\)/ /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

// Then restart Xcode and recommect your devices. You will need to do that for every beta of iOS 10.1+/Xcode 8.

// sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :)
