Why NSInteger instead of NSUInteger in “numberOfSectionInTableView:”?

You can't do the check (if var < 0) return; with an unsigned integer. That is the standard reason for preferring one. Really the only reason to use an unsigned integer is if you need the extra room for larger digits, and you can guarantee the input will never try to be less than zero.
