Answer 1

If you use pagining in collectionView it will scroll by one page Not one cell. You can disable pagining and implement ScrollViewDelegate

- (void)scrollViewWillEndDragging:(UIScrollView *)scrollView withVelocity:(CGPoint)velocity targetContentOffset:(inout CGPoint *)targetContentOffset
 {
     CGFloat pageW = 300;
    int page = scrollView.contentOffset.x / pageW;

    CGFloat newOffset =(page + ((velocity.x > 0)? 1 : -1)) * (pageW - 20);
    CGPoint target = CGPointMake(newOffset, 0);
    targetContentOffset = ⌖
    NSLog(@"end Drag at %f /%i /%f",scrollView.contentOffset.x, page, velocity.x);

 }

Only one different from standart paging: If you drag fast Collection will scroll more than one cell. And don't forget to add UIScrollViewDelegate
