Blank/black screen on device

My app runs fine in the simulator, but when I build and run it on the device (iphone) all I get is a black screen. Any known culprits for why this happens? All code files are in the root directory. [import]uid: 52127 topic_id: 15425 reply_id: 315425[/import]

filenames are case sensitive

are images in 32 bit format? png/jpg

Foo.png on code is not the same as the filename foo.png on device.

cases must match.

Foo.PNG is not the same as Foo.png on device.

on simulator is ok. but not on device.

Ya what carlos said, its most likely your culprit.
