Scrollview 如何在ios中一次移动两个图像

我有一组图像。当我移动一个图像时，剩余的图像也需要沿第一个图像的相同方向移动。 这是我的密码

(void)scrollViewDidScroll:(UIScrollView *)scrollView{
   AppDelegate *app = (AppDelegate *)[[UIApplication sharedApplication]delegate];
   float y = myScroll.contentOffset.y + recipeImageView.frame.origin.y;
   float x = myScroll.contentOffset.x + recipeImageView.frame.origin.x;
   NSLog(@"x Position is :%f , y position is : %f",x,y);

   for(int i=0;i<=[app phhhhh].count;i++){
      UICollectionViewCell *cell = 
         [[UICollectionViewCell alloc]initWithFrame:CGRectMake(10, 
         (self.view.frame.size.height-imageHeight)/2-50, imageWidth , 649)];
      recipeImageView = [[UIImageView alloc] initWithFrame:CGRectMake(x, y, imageWidth , 649)];

      NSIndexPath * indexPath = [_collectionView indexPathForCell:cell];
      NSLog(@"rsdf");
      recipeImageView.image = [UIImage imageNamed:[[app phhhhh] objectAtIndex:indexPath.row]];

      [cell addSubview:recipeImageView];
   }
}

（无效）scrollViewDidScroll:（UIScrollView*）scrollView{
AppDelegate*app=（AppDelegate*）[[UIApplication sharedApplication]delegate]；
float y=myScroll.contentOffset.y+recipeImageView.frame.origin.y；
float x=myScroll.contentOffset.x+recipeImageView.frame.origin.x；
NSLog（@“x位置为：%f，y位置为：%f”，x，y）；
对于（inti=0；i试试这个

[scrollView setContentOffset:CGPointMake(x, y) animated:YES];
