autorelease alternative on ios5

Question

What is the alternative to autorelease in ios5? Previously the following method for table views would work:

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    NSUInteger row = [indexPath row];

    static NSString *TableIdentifier = @"TableIndentifier";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:TableIdentifier];

    if (cell == nil) {
        cell = [[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault 
                                  reuseIdentifier:TableIdentifier]autorelease];
    }

    cell.textLabel.text = [arrAccounts objectAtIndex:row];
    return cell;
}

How ever now i get a message "ARC forbids" and "autorelease is unavailable"... what is the work around for this?

Answer 1

simply remove the autorelease, ARC does the work for you

cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault 
                                  reuseIdentifier:TableIdentifier];

It's damn magic

Answer 2

Remove the autorelease call. AFAIK the compiler is smart enough to realize that it should be autoreleased and synthesizes the appropriate calls for you.

Answer 3

If you don't want to make the required changes for ARC to the current file you can disable ARC for a specific file using a new -fno-objc-arc compiler flag for that file. ARC is enabled using a new -fobjc-arc compiler flag. You can choose to use ARC on a per-file basis if it's more convenient for you to use manual reference counting for some files.
