A Boolean value indicating whether the table view's appearance contains changes that are not reflected in its data source.
- iOS 11.0+
- Mac Catalyst 13.0+
- tvOS 11.0+
The value of this property is
true when the table view contains placeholder cells or is handling a drop and is in the middle of reordering its rows. When this property is
true, avoid making any significant changes to the table view. Specifically, do not call
reload, which forces the table to delete any uncommitted changes before retrieving fresh data from the data source object..
