This is not a fake name. First thing you should do is run the "leaks" performance tool on your app to see if you are leaking memory. This is most likely the problem, otherwise you are using too much memory and you need to find a way to do what you want with less memory.

Help with running the leaks program: Memory leak detection tools

This is definitely not a fake name, and to debug you should first use the Instruments app provided with xcode and specifically look at the 'Allocations' and 'Leaks' instruments from the library.

Run these on your app and it will help you to identify how and where your code is leaking so much memory that it causes the OS to kill it.

There's several ways you can reduce memory usage in a basic app, here's a couple of generic ones:

• Remember to release / autorelease everything you alloc
• Reuse table cells if applicable
• Try to cache things on disk, rather than in memory when loading from a resource
• Remove debug code / features
