-[CFString retain]: message sent to deallocated instance 0x215076c0 - iphone

Question

I know this subject has been discussed several times, but I cannot figure out what is causing this error message. I've been stuck here for a couple weeks now and its driving me crazy. The first part of the method sets up a match for 2-4 players. Once a match is found, it tries to add 3 and 4 players within a certain limit. Right now, the limit is just set to 3 seconds, but I envision it being much larger once it is ready for release.
I know this is a memory error somewhere in the matchmakerViewController code. When I comment out the code changing the scene, I still get the error. Can you show me what I've done wrong and how to fix it?

None of these are from my now code.

Answer 1

The answer ended up being that I needed to release
matchRequest.minPlayers = 3;
matchRequest.maxPlayers = 4;
Before re-defining their values.
