Remarks

A strongly typed implementation of a class that can be used to respond to events raised by the UIScrollView.

The methods on this class can be used to respond to scroll view operations (such as scrolling, zooming, and animations), and in some cases affect those operations.

Constructors

UIScrollViewDelegate(IntPtr)

A constructor used when creating managed representations of unmanaged objects; Called by the runtime.
