The missing part here is the connection between the data and your table view. The table view must implement UITableViewDataSource (and UITableViewDelegate) protocol and must have methods like 

- (UITableViewCell *)tableView:(UITableView *)tableView
     cellForRowAtIndexPath:(NSIndexPath *)indexPath

This one gives you ID of the row and you provide value(s) that should appear in that row

- (NSInteger)tableView:(UITableView *)tableView
     numberOfRowsInSection:(NSInteger)section

This one asks how many rows in total should be in the table. These are called when you call reloadData.

If you have them already, I would check if the arrays you use to populate the table actually contain any data at the time you call reloadData and double check that the reloadData and subsequently the cellForRowAtIndexPath actually get called.
