UIScrollView, reaching the bottom of the scroll view

Question

I know the Apple documentation has the following delegate method:

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView;      // called when scroll         


        

Answer 1

The accepted answer works only if the bottom contentInset value is non-negative. A slight evolution would consider the bottom of the contentInset regardless of it's sign:

CGFloat bottomInset = scrollView.contentInset.bottom;
CGFloat bottomEdge = scrollView.contentOffset.y + scrollView.frame.size.height - bottomInset;
if (bottomEdge == scrollView.contentSize.height) {
    // Scroll view is scrolled to bottom
}
