Question

Application crashes on trying to access [tableView cellForRowAtIndexPath:indexPath] in the heightForRowAtIndexPath delegate method.

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath 
{
    if ([tableView cellForRowAtIndexPath:indexPath] someBOOLProperty]) {
        return kSomeHeight;
    } 

    return kDefaultHeight;
}

Answer 1

(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath

We do not have tableViewCell object at the time above method is called.

I think using [tableView cellForRowAtIndexPath:indexPath] inside the above delegate is not correct.
