Remarks

By setting the ContentOffset property, the application developer can specify the visible portion of the subview. For instance, compare the appearance of an 800x800 image in a UIScrollView with the ContentOffset property set to PointF[0,0] (left image) with the appearance when ContentOffset is set to PointF [240,170] (right image).

var scrollView = new UIScrollView ();
scrollView.ContentSize = new SizeF (800, 800);

var imageView = new UIImageView (UIImage.FromFile ("target800.png"));

scrollView.AddSubview (imageView);
scrollView.ContentOffset = new PointF (240, 170);

Assignment to this value will move the subview instantaneously. If animation is desired, use SetContentOffset(CGPoint, Boolean).
