Question

I am getting this error in iOS 5

-[UITableView dequeueReusableCellWithIdentifier:forIndexPath:]: unrecognized selector sent to instance 0xa217200

However, I get no errors in iOS 6. How can I fix this problem? Here’s my code:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"MyCell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; /// SIGABRT error

    if (!cell)
    {
        cell = [[UITableViewCell alloc]
        initWithStyle: UITableViewCellStyleSubtitle
        reuseIdentifier: CellIdentifier];
    }

    return cell;
}

EDIT: This method is newly added in iOS6+ SDK.

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

But in iOS 5, to create instance of UITableViewCell we generally use this method :-

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

In iOS 5, there is no need of extra parameter which you have used in iOS 6. (forIndexPath:).

So change your method. It will work.
