Hi all,

I am experiencing a weird scrolling issue and I was hoping someone could give me a hand in trying to identify why this is happening.

I have included the part of my code that I think is relevant to the question but am happy to update this post with whatever else is needed.

I have implemented a pull to refresh view in the tableview's content inset area. The refresh fires an Async NSURLConnection that pulls data from a webserver, parses the relevant information and refreshes the table as required.

This is where the refresh process kicks off:

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate{

    if (scrollView.contentOffset.y <= - 65.0f && !self.reloading) {
        self.reloading = YES;
        [self reloadTableViewDataSource];
        [refreshHeaderView setState:EGOOPullRefreshLoading];
        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:0.2];
        self.tableView.contentInset = UIEdgeInsetsMake(60.0f, 0.0f, 0.0f, 0.0f);
        [UIView commitAnimations];
    }
}

Problem is if I start to scroll whilst the content inset is "visible" (i.e. during reload) I get this weird behaviour where my table sections do not scroll all the way to the top - see screenshot for a clear visual of what I am trying to describe here.

I have included a couple of screenshots below that clearly identify what is happening at the moment.

Has anyone experienced this before? Any ideas on what I should be looking at to try and fix it?

Many thanks in advance, Rog

And this is the result if I start scrolling the table. The orange bit at the top of the image is the actual navigation bar, where I would expect the table section (date 1 December 2010) to be.
