App doesn't work when build for Adhoc

I'm facing very strange problem - my app is working nice on a device when build with Debug configuration, but when it's build for AdHoc distribution, 开发者_运维百科it does nothing when started. It simply shows blank screen, no log messages on console, no errors nothing, so I don't have a clue of what's going on, what makes me desperate.

I examined all possible configurations, but without success.

Does anybody experienced such behavior? Any help is highly appreciated.

thanks

Resolved - iWasRobbed was right, my colleague made some changes to the code, enclosing complete startup sequence to condition valid only for Debug configuration build :)
