Question

I’m gettin’ these while i analyze my code:

Method returns an Objective-C object with a +1 retain count

and

Object leaked: object allocated and stored into 'headerLabel' is not referenced later in this execution path and has a retain count of +1

on this method:

 - (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
    {
        // create the parent view that will hold header Label
        UIView* customView = [[UIView alloc] initWithFrame:CGRectMake(15.0, 0.0, 300.0, 44.0)];

        // create the button object
        UILabel * headerLabel = [[UILabel alloc] initWithFrame:CGRectZero];
        headerLabel.backgroundColor = [UIColor clearColor];
        headerLabel.opaque = NO;
        headerLabel.textColor = [UIColor whiteColor];
        headerLabel.highlightedTextColor = [UIColor whiteColor];
        headerLabel.font = [UIFont boldSystemFontOfSize:15];
        headerLabel.frame = CGRectMake(10.0, 0.0, 300.0, 44.0);

        if (section == 0)
            headerLabel.text = NSLocalizedString(@"A", @"A");
        else if (section == 1) 
            headerLabel.text =NSLocalizedString(@"B", @"B");
        else if (section == 2)
            headerLabel.text = NSLocalizedString(@"C", @"C");

        if(searching)
            headerLabel.text = NSLocalizedString(@"SEARCH", @"Search Results");

        [customView addSubview:headerLabel];

        return customView;
    }

Now, expanding the arrows i’m trying to understand, and i suppose that customView is not being deallocated. Is it right?

How can i do to fix it? I’m new to this, help me to understand!

Answer 1

Either add

[headerLabel release];

after

[customView addSubview:headerLabel];

or initialize it like this

UILabel * headerLabel = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease];

of course given that you’re not using ARC
