Solving Issues Like Warning Attempting to Create Use_block_in_frame Variable With Block That Isnt in the Frame
I used to fight for a while with strange issue. I am using Singleton in my iOS application to hold Session information. Unfortunately when using NSMutableArrayList to hold stack of current objects - the references become empty at some point and there is a warning like:
warning: Attempting to create USE_BLOCK_IN_FRAME variable with block that isn't in the frame.
While searching on the net - I have mentioned one comment about using singletons - well - this was my lead.
I am using common singleton macro that defines most of the memory management methods. Exactly in session manager I used the macro, before @synthesize
- this was the problem, static definitions should not appear before synthesized methods. So if you have something like this, just replace it with:
@synthesize loggedUserId, ...
SYNTHESIZE_SINGLETON_FOR_CLASS(SessionManager)
