iOS app eating nearly 40mb at start

Hey, now 开发者_StackOverflow社区when I finally got to test my app on a device it eats 40mb memory at the beginning which is a huge amount. Is there any good way to determine where exactly things went wrong?

Yes, use the memory allocations and leaks profilers that are part of the Instruments application.

You'll probably want to profile it using the Instruments app that comes with Xcode.
