iPhone camera application running fine in iPhone but crashing in iPod

i made an iPhone app that uses camera. It works fine in iPhone, no memory warnings at all. It is also running on iPod touch 4G but gives memory warnings and crashes after some time after getting level 2 warning. If someone can point me the possible reason for this. 开发者_StackOverflowThanks.

The only way you are going to fix this is by being able to debug it on the device. I wrote this blog to explain how to debug EXC_BAD_ACCESS, which is what I assume you are getting

The simplest things to do:

1. Run a Build and Analyze and fix every problem it finds (or at least rewrite it so that B&A doesn't think it's a problem) -- Having a clean B&A is a really good way to making sure you catch these problems early

2. Turn on Zombies and run your program -- this makes the last release sent to an object turn it into a zombie rather than dealloc it. Your program will leak tons of memory, but if you ever send a message to a zombie it will stop right there and you will see a bug that you need to fix, because in your real version, that would be a crash (sending a message to a dealloced object).

It crashes on a specific operation or randomly?

if randomly, use instrument to check your memory leaks and memory usage. It's hard to figure out where the problem lies in without going through all your app.
