UIScrollView doesn't scroll. What's wrong?

I have created a scroll(width 320, height 420) in 'Interface Builder'.

and in class:

 -(void)viewWillAppear:(BOOL)animated {
    [scroll setContentSize:CGSizeMake(scroll.frame.size.width, 1000)];
 }

but the scroll view is not scrolling?

See the print screens

I think maybe you have not successfully added the images or have not successfully set the scrollView's contentSize. And I suggest you to set the contentSize after you add the image view to your scrollView. viewDidLoad is good idea. Most of the time don't do much work in viewWillAppear. The view will not be shown until this method finish.

Check if you init with your scrollView with frame:

self.scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 280, 360)];

Remember also to set contentSize bigger than frame, for example:

self.scrollView.contentSize = CGSizeMake(2*280, 360);

Also add delegate in your interface:

<UIScrollViewDelegate>

And delegate it:

self.scrollView.delegate = self;
