I created two splash screens, 1 that is 640x960, and 1 that is 640x1136. Initially the app was of base size 640x960 so my iPhone 5 was centering the app and black boxing the sides. I then added the 640x1136 splash screen and it used the new larger screen format both on the splash screen as well as increasing the screen size of my app (on both phone and simulator for 4" devices). But now I have deleted the [email protected] file, did clean/rebuild all of my project, but it is still somehow running with the [email protected] version on 4" devices and I cannot figure out why? Is this cached somewhere else that I am not looking correctly?
