Instance Property


A Boolean value indicating whether the collection view contains drop placeholders or is reordering its items as part of handling a drop.


@property(nonatomic, readonly) BOOL hasUncommittedUpdates;


When the value of this property is YES, avoid making any significant changes to the collection view. Specifically, do not reload the collection view's data, as doing so deletes all placeholders and recreates items from the data source.
