iOS 6 Table View crashes when deployed to iOS 5

Apple have changed the UITableViewController template in iOS 6 a bit. Specifically, when you create a new UITableViewController class, it’s created using something like this (in the cellForRowAtIndexPath method):

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
    
    // Configure the cell...
    
    return cell;
}

When run in iOS 5 the app crashes. The culprit seems to be the addition of forIndexPath:indexPath in this declaration which is only available in iOS 6. To make it work in either iOS version, simply take it out, like so:

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier;

The full code from an iOS 5 template is:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier;
    
    // Configure the cell...
    
    return cell;
}
