Hi...Looking in the API and in various sites I understand that WODisplayGroup could be a very useful object for managing a table..I understand how to create it using WOLips or programmatically (I think the following rows are right..)EODatabaseDataSource ds = new EODatabaseDataSource(session().defaultEditingContext(),_table);displayGroup.setDataSource(ds); displayGroup.fetch();But.. I don't understand how to display data managed by my WODisplayGroup...Somebody can explain how to do that?
The primary usage of display groups is in repetitions where you would use displayGroup.displayedObjects() This gives you an NSArray that reflects the sort orderings and qualifiers of your display group. Additionally it returns only a specific batch of objects if you set displayGroup.setNumberOfObjectsPerBatch(int). Of course there is a plethora of other features to discover ;-)
