I\'m trying to convert my iOS 7 app to iOS 8 in Xcode 6 GM, and when i run it on the iPhone 5s or lower simulators with iOS 8 everything is fine, but on the iPhone 6 and 6 P
This bug only occurs if your app is being scaled to fit the resolution of the newer devices.
A quick fix (who knows whether this will even get addressed in 8.1) is to provide the proper resolution loading images in your app package.
From https://developer.apple.com/ios/human-interface-guidelines/graphics/launch-screen/
For iPhone 7, iPhone 6s, iPhone 6:
750 x 1334 (@2x) for portrait
1334 x 750 (@2x) for landscape
For iPhone 7 Plus, iPhone 6s Plus, iPhone 6 Plus:
1242 x 2208 (@3x) for portrait
2208 x 1242 (@3x) for landscape
In my app, we only support portrait, so providing the 750x1334 and 1242x2208 fixed it.
And just to confirm in case it wasn't obvious, you DO need to be using UIStatusBarStyleLightContent for your status bar style.
