Apple has a guide written up for the 32-bit to 64-bit transition as far as things that will cause problems, and I'd guess that you've managed to stumble over one of the situations by accident in your code.
Has anyone else seen this type of behavior or could point me to anything that could be causing this?
It’s hard to say without more information about the problem. There’s two ways you might investigate this further:
Create a small test app that uses UITableView in a way similar to your main app to see if it has problems when run 64 bit.
Dig deeper into the values returned by each of your data source / delegate methods to see if any of them are returning weird results on 64 bit.
