Yes. You can do it. In each page of the mainScrollView add a subScrollView containing the imageView. You need to do the following things.

  1. Set maximumZoomScale for subScrollView

    [subScrollView setMaximumZoomScale:2.0f];   // You can set any value

    This value is calculated based on the size of the image displayed in the imageView.

  2. In the viewForZoomingInScrollView: method of the subScrollView return the imageView

    - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView {

    return imageView;
}

  3. Enable paging in mainScrollView

    mainScrollView.pagingEnabled = YES;

    You have to write further code to handle paging in the mainScrollView.
