UITableView dataSource must return a cell

Question

I am trying to display two different UITableViewCells I have made in InterfaceBuilder, however I am receiving this error.

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:'

I have create two new nib's I have changed the file owners class to the UITableViewController I am trying to display them in, and hooked them up using IBOutlets etc.

The error happens inside TableView:cellForRowAtIndexPath and this is what my method for that class looks like

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    // Configure the cell...
    if(indexPath.section == 0) {
        // Manufactures --->
        if (indexPath.row == 0) {
            cell = nil;
            if (cell == nil) {
                [[NSBundle mainBundle] loadNibNamed:@"CodeSearchTextCell" owner:self options:nil];
                cell = codeSearchTextCell; //Loads tableviewcells with custome xib-cell that I have made in Interface builder
                self.codeSearchTextCell = nil;
            }
            codeTextField.layer.borderColor = [UIColor lightGrayColor].CGColor;
            codeTextField.layer.borderWidth = 0.5f;

            cell.userInteractionEnabled = NO;
        }
        else if  (indexPath.row == 1) {
            cell = nil;
            if (cell == nil) {
                [[NSBundle mainBundle] loadNibNamed:@"CodeSearchCell" owner:self options:nil];
                cell = codeSearchCell; //Loads tableviewcells with custome xib-cell that I have made in Interface builder
                self.codeSearchCell = nil;
            }
            cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; //adds disclosure indicator
            cell.userInteractionEnabled = YES;
        }
    }
    return cell;
}

I am not sure what I am doing wrong but can see clearly when putting the break point on the last line where I return the cell its coming back with no value.

any help would be greatly appreciated.

In this example, I assume you have a UIView subclass named CodeSearchCell :

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

    UITableViewCell *cell = nil;

    if (0 == indexPath.section) {

        if (0 == indexPath.row) {

            NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CodeSearchTextCell" owner:self options:nil];
            CodeSearchTextCell *codeSearchTextCell = [tableView dequeueReusableCellWithIdentifier:@"CodeSearchCell"];

            if ( nil == codeSearchTextCell ) {
                codeSearchTextCell = (CodeSearchTextCell *)[nib objectAtIndex:0];
            }

            cell = codeSearchTextCell;

        } else if (1 == indexPath.row) {

            NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CodeSearchCell" owner:self options:nil];
            CodeSearchCell *codeSearchCell = [tableView dequeueReusableCellWithIdentifier:@"CodeSearchCell"];

            if ( nil == codeSearchCell ) {
                codeSearchCell = (CodeSearchCell *)[nib objectAtIndex:0];
            }

            cell = codeSearchCell;

        } else {

           // If indexPath.row > 1
           // Add logic to make sure cell isn't nil.

    } else {

        // If indexPath.section > 0
        // Add logic to make sure cell isn't nil.

    }

    return cell;
}

i think you should try it this way hope it will help you

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    // Configure the cell...
    if(indexPath.section == 0) {
        // Manufactures --->
        if (indexPath.row == 0) {
            cell = nil;
            if (cell == nil) {
                cell = [[[NSBundle mainBundle] loadNibNamed:@"CodeSearchTextCell" owner:self options:nil] objectAtIndex:0];
            }
            codeTextField.layer.borderColor = [UIColor lightGrayColor].CGColor;
            codeTextField.layer.borderWidth = 0.5f;
            cell.userInteractionEnabled = NO;
        }
        else if  (indexPath.row == 1) {
            cell = nil;
            if (cell == nil) {
                cell = [[[NSBundle mainBundle] loadNibNamed:@"CodeSearchCell" owner:self options:nil] objectAtIndex:0];
            }
            cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; //adds disclosure indicator
            cell.userInteractionEnabled = YES;
        }
    }
    return cell;
}
