Question

I’m trying to return the height of the detailTextLabel in the heightForRowAtIndexPath delegate method. This way my table view cells should be the same height as my detailTextLabel.

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

    NSString *text = cell.detailTextLabel.text;
    CGSize size = cell.detailTextLabel.bounds.size;
    UIFont *font = cell.detailTextLabel.font;

    CGSize labelSize = [text sizeWithFont:font                           
                        constrainedToSize:size
                            lineBreakMode:UILineBreakModeWordWrap];
    return labelSize.height;
}

However I’m getting a EXC_BAD_ACCESS on the following line:

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

Wats wrong with the above piece of code?

Answer 1

The problem is that heightForRowAtIndexPath is called before cellForRowAtIndexPath. So the cell has not been created yet.

If all rows have the same height you can specify a common height for the table. In your viewDidLoad you can just say self.tableView.rowHeight = ABC; You can also set this in Interface builder.
