this has nothing to do with auto layout. I suggest you to edit the title. You should title it `launch screen xib` — wcd, Dec 16 '14 at 09:37

AutoLayout is a layout engine, it has nothing to do with resolution of the device. When iOS launches your app, it will check if the app has the launch image targeted on a specific device(prior to iOS 8) or a launch screen xib file (iOS 8). If it finds it, then iOS will run your app in native resolution of current device.
Because the launch screen xib uses size class, so you can use only one launch screen xib to adopt all different resolution devices. But since launch screen only works in iOS 8, if you use it to support different resolution, you have to be sure you only support iOS 8. If you want to support older iOS versions you can not use launch screen xib.
If you only want your app to run on iOS 8 devices, it's fine to use launch screen xib. But if that's not the case, you should use the old launch images.
