如何使用ARC调试保留计数？

Question

I'm using ARC on my iPhone app and I'm trying to catch a bug that gives me the following output (with NSZombieEnabled, MallocStackLogging and guard malloc ):

*** -[MyCustomClass retain]: message sent to deallocated instance 0x534e00

How can I track a retain count using ARC? What do I do using LLDB console with the instance 0x534e00 (of course any other instance that will appear) in order to find the deallocated instance?

For the record: I'm not using any retain anywhere in my code.

Thank you!

Answer 1

It doesn't mean that YOU are explicitly writing [MyCustomClass retain] . The system is doing that for you. You should use Zombies and Instruments and try to track the problem. At least you know that the problem is with MyCustomClass , which narrows things.

Answer 2

Your choices are: 1. Don't use ARC, or 2. Use ARC. But you can't do both. You can't use non-ARC retain functions while using ARC.
