Crash IOS 7

Hello,

I have a problem since the transition to IOS7, when I click the image I receive the following error:
Terminating app due to uncaught exception 'NSRangeException', reason: '**\* -[__NSArrayM objectAtIndex:]: index 0 beyond bounds for empty array'

I do not get this error when I test my application with IOS6.1.
Everything works correctly in IOS6.1.

Thanks for your help.
