• - bounces

  A Boolean value that controls whether the scroll view bounces past the edge of content and back again.

• - bouncesZoom

  A Boolean value that determines whether the scroll view animates the content scaling when the scaling exceeds the maximum or minimum limits.

• - canCancelContentTouches

  A Boolean value that controls whether touches in the content view always lead to tracking.

• - contentInset

  The distance that the content view is inset from the enclosing scroll view.

• - contentOffset

  The point at which the origin of the content view is offset from the origin of the scroll view.

• - contentSize

  The size of the content view.

• - decelerating readonly

  Returns whether the content is moving in the scroll view after the user lifted their finger.

• - decelerationRate

  A floating-point value that determines the rate of deceleration after the user lifts their finger.

• - delaysContentTouches

  A Boolean value that determines whether the scroll view delays the handling of touch-down gestures.

• - delegate

  The delegate of the scroll-view object.

• - directionalLockEnabled

  A Boolean value that determines whether scrolling is disabled in a particular direction If this property is NO, scrolling is permitted in both horizontal and vertical directions.

• - dragging readonly

  A Boolean value that indicates whether the user has begun scrolling the content.

• - indicatorStyle

  The style of the scroll indicators.

• - maximumZoomScale

  A floating-point value that specifies the maximum scale factor that can be applied to the scroll view's content.

• - minimumZoomScale

  A floating-point value that specifies the minimum scale factor that can be applied to the scroll view's content.

• - pagingEnabled

  A Boolean value that determines whether paging is enabled for the scroll view.

• - panGestureRecognizer readonly

  The underlying gesture recognizer for pan gestures.

• - pinchGestureRecognizer readonly

  A Boolean value that determines whether scrolling is enabled.

• - scrollIndicatorInsets

  The distance the scroll indicators are inset from the edge of the scroll view.

• - scrollsToTop

  A Boolean value that controls whether the scroll-to-top gesture is effective The scroll-to-top gesture is a tap on the status bar; when this property is YES, the scroll view jumps to the top of the content when this gesture occurs.

• - showsHorizontalScrollIndicator

• - showsVerticalScrollIndicator

  A Boolean value that controls whether the vertical scroll indicator is visible.

• - tracking readonly

  Returns whether the user has touched the content to initiate scrolling.

• - zoomBouncing readonly

  A Boolean value that indicates that zooming has exceeded the scaling limits specified for the receiver.
