I'd like to re-enable the letterbox mode on the iPhone 5 for my app. Using Xcode 4.5.2 and building an app for iPhone 5, I generated an 1136x640 launch image and it was named Default-568h@2x.png. I have sinced removed the launch screen and in the project summary the space for that image is empty. Also, I have removed any instances I found within the project folder. However, my app continues to be displayed using the full screen on the iPhone 5 and what I want is to be able to use the letterbox mode again. I believe this can be accomplished by deleting the app, but how can I re-enable the letterbox mode using the iPhone 5 and Xcode 4.5.2 without deleting the app from the phone?
Tap 'Product'->'Clean' in Xcode and remove the application from your phone. Then rebuild your project and there shouldn't be any cached version of the Default-568h@2x.png anywhere.
