Question

Is there any way to know programmatically user is running Appstore version or developer version? Any help will be really appreciated.

If you only need to differ between a debug version deployed from Xcode and a release build (ad-hoc or AppStore) you can use the mentioned method of adding a preprocessor macro.
Select your target and select build settings, search for Preprocessor Macros, under Debugyou can add e.g. DEBUG=1.
In your code you can have functionality conditionally compiled by doing something like this:

#ifdef DEBUG
[self enableDebugMode];
#else
[self enableReleaseMode];
#endif
