How to implement scrollViewDidScroll: method? - ios

Question

I'm building an article reading app.List of articles is in UITableViewController,I'm facing an issue when i use scrollViewDidScroll: method first cell of table is display under the UINavigationBar.But when commented this code it displays fine means first cell exactly after the UINavigationBar.
here is my code:
- (void)scrollViewDidScroll: (UIScrollView*)scroll {
// UITableView only moves in one direction, y axis
CGFloat currentOffset = scroll.contentOffset.y;
CGFloat maximumOffset = scroll.contentSize.height - scroll.frame.size.height;
// Change 10.0 to adjust the distance from bottom
if (maximumOffset - currentOffset <= -60.0) {
x++;
[self LoadMore];
[self.tableView addInfiniteScrollingWithActionHandler:^{
}];
[self.tableView reloadData];
}
}

This answer may not be the solution to your problem. This is to point out a major flow in your code that could be the cause of your problem.
You should not reload data [self LoadMore];[self.tableView reloadData]; directly inside scrollViewDidScroll: method. This will cause the method to be called multiple times as you scroll.
And I think you have implemented infinite loading incorrectly.
This code should be placed inside some initializer method (e.g., viewDidLoad)
[tableView addInfiniteScrollingWithActionHandler:^{
[self LoadMore];
[self.tableView reloadData];
// call [tableView.infiniteScrollingView stopAnimating] when done
}];
If you are planing to load more items as you scroll, I don't think you need to use scrollViewDidScroll: at all. Simply put the above code inside viewDidLoad: and everything should work. You will have to keep track of the number of items loaded separately. Hope this will help. :)
