Method Documentation

reuseIdentifier

This view's reuse identifier.

@property (nonatomic, copy) NSString* reuseIdentifier;

Discussion

Used by NIViewRecycler to pool this view into a group of similar recycled views.

initWithReuseIdentifier:

Initializes a newly allocated view with the given reuse identifier.

- (id)initWithReuseIdentifier:(NSString *)reuseIdentifier;

Discussion

This is the designated initializer.

Parameters

reuseIdentifier

The identifier that will be used to group this view in the view recycler.

prepareForReuse

Called immediately after the view has been dequeued from the recycled view pool.

- (void)prepareForReuse;

pageDidDisappear

Called after the page has gone off-screen.

- (void)pageDidDisappear;

Discussion

This method should be used to reset any state information after a page goes off-screen. For example, in the Nimbus photo viewer we reset the zoom scale so that if the photo was zoomed in it will fit on the screen again when the user flips back and forth between two pages.

setFrameAndMaintainState:

Called when the frame of the page is going to change.

- (void)setFrameAndMaintainState:(CGRect)frame;

Discussion

Use this method to maintain any state that may be affected by the frame changing. The Nimbus photo viewer uses this method to save and restore the zoom and center point. This makes the photo always appear to rotate around the center point of the screen rather than the center of the photo.
