Instance Property


Denotes whether cell and data prefetching are enabled.


@property(nonatomic, getter=isPrefetchingEnabled) BOOL prefetchingEnabled;


When YES, the collection view requests cells in advance of when they will be displayed, spreading the rendering over multiple layout passes. When NO, the cells are requested as they are needed for display, often with multiple cells being requested in the same render loop. Setting this property to NO also disables data prefetching. The default value of this property is YES.
