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

I Think @bensnider answer is correct, But not exart. Because of these two reasons

1. - (void)scrollViewDidScroll:(UIScrollView *)scrollView{}

This method will call continuously if we check for if (bottomEdge >= scrollView.contentSize.height)

2 . In this if we go for == check also this condition will valid for two times.

• (i) when we will scroll up when the end of the scroll view touches the bottom edge
• (ii) When the scrollview bounces back to retain it's own position

I feel this is more accurate.

Very few cases this codition is valid for two times also. But User will not come across this.

- (void)scrollViewDidScroll:(UIScrollView *)scrollView
 {
    if (scrollView.contentOffset.y == roundf(scrollView.contentSize.height-scrollView.frame.size.height)) {
    NSLog(@"we are at the enffffdd");

   //Call your function here...

    }
}
