UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath / Assertion failure messages

Question

Implemented UITableView with custom UITableViewCell with below code

    @interface ProfileSaveViewController : UITableViewController
     {
         UITableViewCell *cell0;
         UITableViewCell *cell1;
         UITableViewCell *cell2;
         UILabel *cell2Label;
     }

    @property (nonatomic, retain) IBOutlet UITableViewCell *cell0;
    @property (nonatomic, retain) IBOutlet UITableViewCell *cell1;
    @property (nonatomic, retain) IBOutlet UITableViewCell *cell2;
    @property (nonatomic, retain) IBOutlet UILabel *cell2Label;

    @end

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:               (NSIndexPath*)indexPath
  {
        if([indexPath row] == 0) return cell0;
        if([indexPath row] == 1) return cell1;
        if([indexPath row] == 2) return cell2;   
        return nil;
  }

follwing message came when running the application.

Answer 1

You're being asked for a cell and returning nil (or maybe something else that's not a UITableViewCell). It's just that simple.

I see two possibilities:

• You are returning a number larger than 3 from tableView:numberOfRowsInSection:. Don't.

• One or more of your cell# outlets is not hooked up in your nib, or is not hooked up to a UITableViewCell (or subclass). Hook them up properly.
