Load more cell Problem

[diabolo]

Hi,
i need your help guys
i have Load more button with TableFooterView and when i scroll down to the last cell its Automatically load more cells to the table. so Its Working but there is kind of bug if i scroll down to the last cell and then immediately do it again (scroll up and down to the last cell) its called 2 times.

i need to find a way that even if i "play" with the last cell its called only once until the task is over and then enable it again.

i know that i need to use bool but i dont know how, where and when to do it...

Code:
viewDidLoad

//set tableview footer
    [[NSBundle mainBundle] loadNibNamed:@"ActivityIndicator-iPhone" owner:self options:nil];//this gets a new instance from the xib
    self.footerActivityIndicator=self.activityIndicator;
    [[self tableView] setTableFooterView:[self activityIndicatorView]];

- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
	if (([scrollView contentOffset].y + scrollView.frame.size.height) == [scrollView contentSize].height) {
        NSLog(@"scrolled to bottom");
        [[self footerActivityIndicator] startAnimating];
                [self performSelector:@selector(stopAnimatingFooter) withObject:nil afterDelay:0.5];
        }  

        return;
	}

//stop the footer spinner
- (void) stopAnimatingFooter{
    //add the data
    [[self footerActivityIndicator] stopAnimating];
    [self addItemsToEndOfTableView];
    [[self tableView] reloadData];
}

- (void) addItemsToEndOfTableView{
    
    NSLog(@"addItemsToEndOfTableView");
    // Parse
	NSURL *feedURL = [NSURL URLWithString:@"http://gdata.youtube.com/feeds/api/users/RayWilliamJohnson/uploads?v=2&alt=rss&sort_field=added&start-index=21&max-results=20"];
	feedParser = [[MWFeedParser alloc] initWithFeedURL:feedURL];
	feedParser.delegate = self;
	feedParser.feedParseType = ParseTypeFull; // Parse feed info and all items
	feedParser.connectionType = ConnectionTypeAsynchronously;
	[feedParser parse];
    
    
    
}

Just as you said, you can use a BOOL ivar. I'd name it something like "loadingItems". In your scrollViewDidScroll, just before you startAnimating, wrap that in an "if" statement, where you check if "loadingItems" == NO. If it equals YES, then you don't need to do anything because your items are already loading.

Now, in your addItemsToEnd... method, after you are done parsing, just set loadingItems = NO.
