they said even after a reboot, there is no difference. Heres the kicker, it works perfectly on my iPhone 3GS, and in the simulator with NO memory leaks.

So, what on earth do i do?

Answer 1

As others have said, you are using too much memory.

If you are using multiple pages of view controllers, try this simple test - run your app with the ObjectAlloc Instrument. Click on something to bring up a subview, you should see your memory increase - now dismiss that view and go back to the main one, the memory should go down. If it does not, that is your problem (or one of them anyway, but that is a likley starting point).

To try and track this down, place breakpoints in dealloc for each of your view controllers and see what actually gets called. For view controllers that are not released like you expect, in ObjectAlloc you can see where each retain against an object was issued, and decide what retained the object when it should not have done so.

In general the ObjectAlloc flow should look like a graph that goes up and down all the time, not constantly rising.

Also if you are using a lot of images consider re-sizing them to the exact size you need instead of starting with a much larger size and scaling. Using that much memory must be due to using images and not releasing them. Leaks will not report anything if you still have references to memory you are retaining.

Also, buy an older Touch for testing.
