Question

I have subclassed UITableViewCell as MyCell and am attempting to get the table to show. I always receive the message:

exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:

The code for tableView:cellForRowAtIndexPath is as follows:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
MyCell* cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// Configure the cell...
MyCell* theCell = (MyCell *)cell;
UILabel* lab = theCell.theLabel;
lab.text = @"This is the label text";
return cell;
}

I have set the CellIdentifier as “Cell” in the nib. I thought I was returning a cell with the last line?
Where am I going wrong?

Your cell must be nil. You should white something like:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    MyCell* cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (!cell) {
        cell = [[NSBundle mainBundle] loadNibNamed:@"MyCell"].lastObject;
    }
    // Configure the cell...
    UILabel* lab = cell.theLabel;
    lab.text = @"This is the label text";
    return cell;
}
