exc bad access code 2

Question

I have been struggling with this error for the last 3 days and no luck. I'm developing a combined app with uiviewcontrollers and uitableviewcontrollers and in table views I click the add button and it crashes. (no core data coding has been added yet). I have even enabled NSzombies and Guard Malloc and the following points of crashing are on these codes. Please help as I need to try chase a deadline and I don't want to go further in development with the gremlin in the project.

Answer 1

Use the "Zombie" tool in Instruments.

Open menu Product > Profile. Xcode opens instruments, where you can select a tool. Select Zombie. The app will open in simulator then recreate the EXC_BAD_ACCESS error. Instruments will show you what variable and on what function raised this error.
