Problem with UIScrollView

[isayeter]

When I use a UIScrollView for addParallaxWithView:

It doesn't scroll with the main view.

Any solution ?

UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0,0,320,160)];
scrollView.contentSize = CGSizeMake(320, 170);
scrollView.showsHorizontalScrollIndicator = YES;
scrollView.showsVerticalScrollIndicator = NO;
scrollView.pagingEnabled = true;
scrollView.scrollEnabled = true;
scrollView.backgroundColor = [UIColor blueColor];
scrollView.tag = 9999;
scrollView.delegate = self;


UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Rover.jpg"]];
[imageView setFrame:CGRectMake(0, 0, 320, 160)];
[imageView setContentMode:UIViewContentModeScaleAspectFill];
[scrollView addSubview:imageView];


[_collectionView addParallaxWithView:scrollView andHeight:160];
