I'm not sure I understand your question fully (if you can attach code it will be very helpful), I suggest reading this short post -gcd-queues-synchronization Maybe you can make sure that the function is running on the same queue (thread) using GCD and it will solve your synchronization problem.

Absolutely. At the end of the day, code running under GCD is just code running on a regular, old OS thread that just happens to be managed by GCD. As @Daniel points out, if you're using GCD throughout, you ought to use GCD's mechanisms for mutual exclusion (i.e. a serial queue), but if you're interoperating with legacy code that uses pthread mutexes to lock resources, you can certainly do that from within code executed by GCD as well.
