Update:
CGRect rect = [scrollView bounds];
UIGraphicsBeginImageContextWithOptions(rect.size,YES,0.0f);
CGContextRef context = UIGraphicsGetCurrentContext();
[scrollView.layer renderInContext:context];
UIImage *capturedImage = UIGraphicsGetImageFromCurrentImageContext();
The scroll view's bounds.origin is also its contentOffset, which is likely what
is happening when you render it in to the context.
However, you seem to imply that you just have a simple scroll view with a
simple image inside – why do this at all?
Instead just use the contentOffset to determine

I wanted to follow up and let you know this is indeed working for me. Forgot to

Hi Trygve,
The UIScrollView adds these subviews to what's called a contentView. This is
why you have to change a content size to adjust your scrolling, vs changing the
frame of the UIScrollView. You're grabbing the wrong layer.
You can grab the correct view / layer: [[scrollView contentView]

I am trying to take a snapshot of my UIScrollView and store it in a

[scrollView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

Does it do that even if the scroll view isn't scrolled at all but is at the
very top?
