Question

I have a custom cell for my table view which I have designed using interface builder. In its .m file I have some code like this to fetch the xib from the bundle for the custom cell.

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        NSArray *nibArray = [[NSBundle mainBundle] loadNibNamed:@"SubItemsCustomCell" owner:self options:nil];
        self = [nibArray objectAtIndex:0];    }
    return self;
}

Then when I use this cell in my cellForRowAtIndexPath method and pass it an autorelease message

if (!cellForSubItems) {
    cellForSubItems = [[[SubItemsCustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"SubItemCell"] autorelease];
}

it crashes when i scroll the tableView giving a message,

-[SubItemsCustomCell release]: message sent to deallocated instance 0xed198b0

It never crashed when I made a custom cell using code, but it does here, why is it so??
Also when I dont autorelease it, it runs absolutely fine, but obviously it will have memory leaks.
Kindly Help me out with this one. Thanks In Advance.

EDIT: I am not using ARC.

try my bellow code for add cell in UITableView

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        SubItemsCustomCell *cell = (SubItemsCustomCell *) [tableView      dequeueReusableCellWithIdentifier:nil];

        if (cell == nil) 
        {

            NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"SubItemsCustomCell" owner:self options:nil];

            for (id currentObject in topLevelObjects){
                if ([currentObject isKindOfClass:[UITableViewCell class]]){
                    cell =  (SubItemsCustomCell *) currentObject;
                    break;
                }
            }
             ///do something here
        }

        return cell;
    }

i hope this help you…
