I'm trying to integrate FB into an existing iOS app.
I've modified the HelloFacebookSample app to use my app ID, display name, and bundle identifier. I can run it and post from it just fine (running in the iOS 6 emulator). So that leads me to believe my settings on developers.facebook.com are correct.
Next I looked at the code in the app delegate and view controller in the sample and duplicated it in my own code. The first bit of Facebook code that gets executed is in the app delegate, in applicationDidBecomeActive:. I execute the same two lines as the sample app:
[FBAppEvents activateApp];
[FBAppCall handleDidBecomeActive];
If I run my program, I eventually get EXC_BAD_ACCESS (code=2, address=0x0). In the debug navigator I see:

If I remove [FBAppCall handleDidBecomeActive] I get the same result. So this seems to be a result of [FBAppEvents activateApp].
If I remove [FBAppEvents activateApp], which I understand to be optional anyway, and only call [FBAppCall handleDidBecomeActive], I can launch the app. But then when I try to create an instance of FBLoginView in my view controller:
FBLoginView * loginview = [[FBLoginView alloc] init];
I get the same error (EXC_BAD_ACCESS (code=2, address=0x0)):

Don't be fooled by the fact that I'm obviously not creating my FBLoginView in viewDidLoad. The point is that the first call to anything that tries to do anything with my Facebook session fails in the same way. It looks like it's trying to do something with a handler in both cases. The identical code works with MY Facebook identifier, bundle ID, etc. in the sample code, but doesn't work in my app. I'm suspecting compiler/linker settings or some other configuration difference between my app and the sample, but I'm not sure where to begin to look. Everything I've looked at looks the same between my app and the sample.
I've tried a lot of different ways to open a Facebook session and get the permissions I need, but they all fail the same way. This seemed like a good one to post here since the sample works but the same code in my app doesn't.
Thanks for your help.
EDIT: I see in my build settings that the sample app uses ARC. I do not. I'm hesitant to convert a large, functioning app at this point in its lifecycle.
