SIGABRT from uiview background image?

I tried putting a background image onto my view screen, unsuccessfully I might add. When I ran it I got SIGABRT taking me back to main.m. I tried reducing the image size, deleting the image, and finally just commenting out the code I had added to do it. Yet it still doesn't run. This is what shows up in the debug area:

2011-07-23 08:10:23.829 Soleternity[1229:fe03] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIApplication 0x7209da0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key play.'

That could happen because your image is missing from the build bundle somehow. Try:

• Remove your image
• Clean your build.
• Add it again and build.

You can also check if the image is really called play.

Also, are you adding an image to an UIImageView IBOulet?

Edit 1:

Have you done:

 #import <AVFoundation/AVAudioPlayer.h>

And also added the framework to your build?
