Default value is true.
By default, a UIScrollView intercepts touches before they propagate to subviews and, if a scrolling gesture is made, cancels those touches from being passed to the underlying UIView (instead, both the UIScrollView and the UIView subview receive TouchesCancelled(NSSet, UIEvent) events). By setting this property to false, the application developer specifies that touches immediately propagate to the underlying UIView. This can avoid potentially-perceptible delays in activating subviews, but makes it impossible for the UIScrollView to recognize scrolling and panning gestures. In this situation, it is up to the application developer to develop a logical and consistent model for scrolling. This may involve the use of UIGestureRecognizers, overriding TouchesShouldBegin(NSSet, UIEvent, UIView), TouchesShouldCancelInContentView(UIView)
