<NISnapshotRotationDelegate> Protocol Reference

Overview

The methods declared by the NISnapshotRotation protocol allow the adopting delegate to respond to messages from the NISnapshotRotation class and thus implement snapshot rotations.

Inherited by NITableViewSnapshotRotation().

Method Documentation

containerViewForSnapshotRotation:

Tells the delegate to return the container view of the rotating view.

- (UIView*)containerViewForSnapshotRotation:(NISnapshotRotation *)snapshotRotation;

Discussion

This is often the controller's self.view. This view must not be the same as the rotatingView and rotatingView must be in the subview tree of containerView.

   @sa NISnapshotRotation::rotatingViewForSnapshotRotation:

rotatingViewForSnapshotRotation:

Tells the delegate to return the rotating view.

- (UIView*)rotatingViewForSnapshotRotation:(NISnapshotRotation *)snapshotRotation;

Discussion

The rotating view is the view that will be snapshotted during the rotation.

This view must not be the same as the containerView and must be in the subview tree of containerView.

   @sa NISnapshotRotation::containerViewForSnapshotRotation:

fixedInsetsForSnapshotRotation:

Asks the delegate to return the insets of the rotating view that should be fixed during rotation.

- (UIEdgeInsets)fixedInsetsForSnapshotRotation:(NISnapshotRotation *)snapshotRotation;

Discussion

This method will only be called on iOS 6.0 and higher.

The returned insets will denote which parts of the snapshotted images will not stretch during the rotation animation.
