在另一个ui滚动视图的顶部添加分页的ui滚动视图

Question

I'm have a vertical scroll and I want to add a paged scroll view on top of it to go through a set of pictures. I have both of scroll views set up through the interface builder. For the vertical scroll I have the following where scroll is the UIScrollView

-(void)createScroll{
[scroll setScrollEnabled:YES];
[scroll setContentSize:CGSizeMake(320, 1325)];
}

For the paged scroll I have the following where scrollView is the UIScrollView

for (int i = 0; i < array.count; i++) {
    CGRect frame;
    frame.origin.x = self.scrollView.frame.size.width * i;
    frame.origin.y = 0;
    frame.size = self.scrollView.frame.size;

    UIView *subview = [[UIView alloc] initWithFrame:frame];
    subview.backgroundColor = [array objectAtIndex:i];
    [self.scrollView addSubview:subview];

}

self.scrollView.contentSize = CGSizeMake(self.scrollView.frame.size.width * array.count, self.scrollView.frame.size.height);

self.pageControl.currentPage = 0;
self.pageControl.numberOfPages = array.count;

The problem is that the images are not showing up in the paged scroll view. I put the paged scroll into a single view test app and it works fine, however it doesn't work when I add it on top of the vertical scroll. I have a feeling that it has something to do with adding it to the subview, but I'm new to obj-c and not sure what order the subviews should go in. Anybody have any advice? Cheers!

我是在viewDidLoadMethod中创建滚动视图的，一旦在（void）viewDidAppear：（BOOL）动画方法中创建了滚动视图，滚动视图就可以完美地工作了。
