Row number in UITableViewController does not conform the protocol function

Question

I use a dynamic tableViewController. I implement the numberOfSection to return 4, and the numberOfRowInSection return 1. These are the only changes I made for the blank TableViewController. But when I run it on simulator, it shows multiple cells, which I expected to be only four cells. Why is that?

Note: If I change the height of each cell to let the screen only fit four cells at a time, it will work fine since it won't let be me scroll down. So I guess is the tableViewController always try to fill the screen no matter how many cell it should display?

Yes, the UITableView will always continue to fill the screen with 'empty' cells of the default row height. To prevent this, you could add the following code in viewDidLoad:

self.tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];

(For Swift, check @VictorSigler's answer.)

Thanks for you answer and it works! One more question: CGRectZero is just like CGRect(0,0,0,0), How the whole footerView place be covered with a "nothing" CGRect? – Zhehao Victor Zhou Jul 17 '15 at 21:28
I'm not sure, but I think it just overrides the default footer. – Glorfindel Jul 17 '15 at 21:29

In Swift:

self.tableView.tableFooterView = UIView(frame: CGRect.zeroRect)

@ZhehaoVictorZhou You're welcome you can see more about `CGRectZero` in this answer http://stackoverflow.com/questions/22217964/can-any-one-please-explain-what-is-use-of-cgrectzero – Victor Sigler Jul 17 '15 at 21:29
Thanks! however that actually make me more confused about why a "nothing" CGRect can cover the tableFootView. – Zhehao Victor Zhou Jul 17 '15 at 21:31
