UITableView setContentOffSet is causing unwanted scrolling to the top

I am simulating a pull to refresh when my view loads which fetches data from an api.

[refreshControl beginRefreshing];
CGPoint newOffset = CGPointMake(0, -refreshControl.frame.size.height);
[tableView setContentOffset:newOffset animated:YES];

when the data comes back it stops the refresh control, reloads the tableview and

 [refreshControl endRefreshing];   
 [_postsTableView setContentOffset:CGPointZero animated:YES];

If am at the top of the tableview fine, but if am in the middle or at the bottom it scrolls to the top undesirably.

Looks like you can just wrap that to avoid the undesired behavior:

if (_postsTableView.contentOffset.y < 0) {
    [_postsTableView setContentOffset:CGPointZero animated:YES];
}
