You can track memory leaks with Instruments: see this tutorial.

If you're familiar with Valgrind, you use it on x86 binaries built against the iPhone Simulator SDK: see how Landon Fuller does it.

EDIT: Another Stackoverflow answer suggests the Clang analyser: static analysis of the code may detect memory allocation errors as well. I never used this tool myself but it's good to know it's possible.

There are many questions here which point to various memory management resources. These include

There's Apple's Instruments.app in your /Developer/Applications folder, which is intended to test appplications for leaks and other errors.

I believe you will find a good tutorial.

Instruments is the way to go. It can tell you exactly which line leaked the memory. – Mike Weller Jan 16 '10 at 12:42
