Question

I have a scrollView which is a UIScrollView in a CustomCell which is a subclass of UITableViewCell. I have two different pages in a cell. So, I’m using my scrollView in pagingEnabledmode.

My question is that can i change my scrollView background color after passing second page then set it back to initial color after returning back ?

So far, i tried to use two different UIScrollView, then i realized that i can’t use pagingEnabled mode.

To be more specific, i want my initial screen which width is 360 and height is 70 in blue,and my second screen is green which starts after 360 px.

Answer 1

Try to use the scrollViewDelegate

- (void)scrollViewDidScroll:(UIScrollView *)sender {
           CGFloat pageWidth = 360;
           int page = floor(scroll.contentOffset.x / pageWidth) ;

           if (page == 1) { /// second scroll page
               myView.backgroundColor = [UIColor greenColor];
           } else {  ///first scroll page
               myView.backgroundColor = [UIColor blueColor];
           }

}
