Question

I am looking for an example that show just vertical scrolling in iPhone.

• The Apple supplied Scrolling example allows swiping of images left to
  right.

  1. Example Link
  2. Example Link

• I want to have my images scroll top to bottom like Instagram
  App.

• I research about it and found lots of example, but they all show
  horizontal scrolling.

  1. Example
  2. Example
  3. Example

Does anyone know how to do this?

I appreciate if you send me a link to a tutorial.

Hi i solved your problem with apple code,

just change the function with

- (void)layoutScrollImages
{
    UIImageView *view = nil;
    NSArray *subviews = [scrollView1 subviews];

    // reposition all image subviews in a horizontal serial fashion
    CGFloat curXLoc = 0;
    for (view in subviews)
    {
        if ([view isKindOfClass:[UIImageView class]] && view.tag > 0)
        {
            CGRect frame = view.frame;
            frame.origin = CGPointMake(0,curXLoc);
            view.frame = frame;

            curXLoc += (kScrollObjHeight);
        }
    }

    // set the content size so it can be scrollable
    [scrollView1 setContentSize:CGSizeMake(([scrollView1 bounds].size.width),kNumImages * kScrollObjHeight)];
}  

or if you want sample then i will give you
