I am playing with my Xcode, following tutorial, learning this stuff. I added an image to \"Launch Images\", rebuilt my project, it showed up.
I removed the
Navigate to the project folder, go to Resources folder and delete the folders called splash and icon (do this from both from Xcode and Finder). Also delete the app from either the device or the simulator by pressing on it and x-ing it out then go to Product->Clean.
I know this was very painful, but now you can set the new icons and launch images from Xcode.
Good luck.
