I have an app that when run normally crashes silently, nothing printed to the console whatsoever. When run in build and debug I finally get that familiar EXC_BAD_ACCESS at the bottom (nothing shows up with bt though), along with some nonsense that I can't decipher in the debugger window. I've tried to find the problem with NSLog, but as far as I can tell all my functions get hit and finish. I've also tried turning on NSZombies, nut I don't think I fully understand this process. There is a lot of code, and I'm not sure where the problem is so I'm not posting it, but I am wondering if anyone has any good strategies for this kind of thing?
