First I have set delegate in .h file
@interface ViewController : UIViewController<UICollectionViewDataSource, UIScrollViewDelegate>
After that just call this method in collection view .m file
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
NSLog(@"scrollViewDidScroll");
}
but not call this method.
Just do simple
add below line in .m
file
yourCollectionView.delegate = self;
and below add in .h
UICollectionViewDelegate
remove
UIScrollViewDelegate
