I'm basically inserting new rows, deleting rows that are no longer there, and reloading rows that exist in both the old and new data. For example: Before, the list dat...
I'm having a very strange problem with the UINavigationController. I found a very similar question here: http://stackoverflow.com/questions/1542040/uinavigationcontroller-not-popping-uinavigationbar-items but the solution there had to do with the fact that the guy had added a category to NSMutableArray, and I'm not doing anything like t...
