Random Crashing and weird console output

I wrote an entire app, and I was just about to submit it to the app store, and in my final testing, I went back and added a few releases to ensure proper memory management was observed. And since then, I keep getting these random crashe开发者_开发知识库s. I've tried removing some or all of the release calls, I've tried retaining objects. I cleaned the project. I used NSZombieEnabled and that also is not helping. All this to not avail.

Most of the time, the console says provides no help. Usually the app loads, I put NSLogs in viewDidLoad, viewDidAppear, and viewWillAppear, and they all show up in the console, then it crashes.

Sometimes I also get EXC_BAD_ACCESS (and I know what that means). But its occurring randomly. So this doesn't make sense to me. Thanks for any help possible. I've written this whole app, and spent months on it. So I'm really stuck. Thank you.

Have you tried Build --> Analyze? It will search your code for leaks and other useful things you might have missed. Try that and see if it finds anything for you.

I agree with Rudy. It sounds like you're releasing something that is still in use. I would go back to the version that was working and start adding the releases one at a time til it causes the crash. Slow but effective debugging.

When you say that you "sometimes" get EXC_BAD_ACCESS, what do you get the rest of the time? Where does the crash stack indicate you're crashing? What messages do you get?

Random crashes usually indicate a timing problem. A common cause is accessing things on multiple threads. Are you? It can also mean timing differences based on network traffic.

Make sure the console doesn't indicate an exception rather than a memory violation. Usually there's something in the console that will be useful.
