Question

Hey guys,
I’m new to Objective-C, and I’m making an app, and when you click on a table cell it does what it’s supposed to, but when you go back and click on the cell the second time, it crashed with “EXC_BAD_ACCESS”. Could you tell me what it means, and why is it only crashing the second time, and how could I fix it? I’m pretty sure it’s in this function:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Navigation logic may go here. Create and push another view controller.

    RaceData * data = [self.units objectAtIndex:indexPath.row];
    ProtossInfo * info = [[ProtossInfo alloc] initWithNibName:@"ProtossInfo" bundle:nil];

     // ...
     // Pass the selected object to the new view controller.
    [self.navigationController pushViewController:info animated:YES];

    info.title = data.titler;
    info.minerals.text = data.min;
    info.vespene.text = data.vesp;
    info.supply.text = data.sup;
    info.portrait.image = data.porty;

    [info release];
    [data release];

}

You’re releasing data, which you didn’t retain.
