Question

I’m having a problem with my iOS app and getting a UILabel in a UITableViewCell to wrap. The text shows but it will only display on one line.

Here is my code:

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

    UILabel *noteLabel = (UILabel *)[cell.contentView viewWithTag:2];

    NSDictionary *contact = [jsonResults objectAtIndex:indexPath.row];
    noteLabel.lineBreakMode = UILineBreakModeWordWrap;
    noteLabel.numberOfLines = 0;
    noteLabel.text = [contact objectForKey:@"note"];   
    return cell;
}

I believe the problem has something to do with this line:

UILabel *noteLabel = (UILabel *)[cell.contentView viewWithTag:2];

I’m not sure how else to get the label from a tag and I think this line won’t let me change the labels properties.

You may need to set the label’s height:

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

    UILabel *noteLabel = (UILabel *)[cell.contentView viewWithTag:2];

    NSDictionary *contact = [jsonResults objectAtIndex:indexPath.row];
    noteLabel.lineBreakMode = UILineBreakModeWordWrap;
    noteLabel.numberOfLines = 0;
    noteLabel.text = [contact objectForKey:@"note"];

    //Note: adjust the proper width to be constrained to
    CGSize size = [noteLabel.text sizeWithFont:noteLabel.font forWidth:150 lineBreakMode:noteLabel.lineBreakMode];
    CGRect labelFrame = noteLabel.frame;
    labelFrame.size = size;
    noteLabel.frame = labelFrame; 

    return cell;
}
