问题 I'm using an asset catalog with Xcode 5.1 and making an app for iOS 7 and above. The idea behind an asset catalog is that you can call the images whatever you want and the catalog associates the image with the correct device and orientation.

问题 In iOS 7, many apps are changing the appearance of the status bar and clearly something has changed to the status bar of web apps as well. It looked like web app developers would be able to influence the color of the bar, but this didn't turn out to be easy.

Thats not a great solution. Tried and tested
