如何使用Parse Table View Controller进行无限滚动？

Question

我想要无限滚动，所以我想我会尝试这段代码，但每当我滚动时我都会崩溃：

代码：

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    if (scrollView.contentSize.height - scrollView.contentOffset.y < (self.view.bounds.size.height)) {
        if (![self isLoading]) {
            [self loadNextPage];
        }
        else{

        }
    }
}

崩溃错误：

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'attempt to delete row 0 from section 1, but there are only 1 sections before the update'
