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.

You will need to symbolicate the stack trace and show us the relevant source; would you expect anyone to recognize that assembler? – Schnitzler

Use breakpoint and check what's wrong.. and as @Schnitzler has told you we are not assemblers – Charlot

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.

Thank you! Using the Zombie pointed me to right place! found but straight away! – Pronto

How to do that when the error appears when I am unit testing a class? – Stelle

Frankly, I don't have experience in working Instruments with unit testing. You can try manually attach Instrument (Zombie tool) to app process... – Sprinkle

@idmean It doesn't show the function or variable, where can I access it? – Noblewoman
