Fixing iPhone memory leaks, getting started

I am an experienced C/C++ programmer, and familiar with memory management issues. I've also shipped a couple small iPhone apps in the past. I am attempting to check my latest app for memory leaks, and I can't make any headway, because there are so many of them. Just starting the app and viewing the first screen shows over 12,000 leaks.

I know I've probably overlooked various things, but I was reasonably cautious in writing the code. I made attempts to release everything I alloc'ed in my dealloc method. It is like my app delegate never gets released, because I can see a couple things that are only alloc'ed once, in the app delegate's init method. They are never modified, and are released in the dealloc method.

This app is built around a tab controller, with around 15 views mainly set up using Interface Builder.

Any help would be appreciated.

Instruments of apple is pretty advanced.. it can show you the exact method that originally created the memory leak, I suggest taking a look at those methods and carefully reading your code ,there usually is this line of code in there and you thought OMG how could I be that stupid.

If that doesn't help, try to "Analyze" with xcode, its pretty good at finding errors and leaks in your code and saved my * a couple of times.
