TOPIC: SCPropertyTypeObjectSelection

SCPropertyTypeObjectSelection 1 year, 5 months ago #1

Hi,

I have setup my propertyDefinition as type SCPropertyTypeObjectSelection and based on a ClassDefinition as follows :

 
SCClassDefinition *subAreaClassDef =
	[SCClassDefinition definitionWithEntityName:@"SubAreaType" withManagedObjectContext:managedObjectContext
								  withPropertyNames:[NSArray arrayWithObjects:@"name", nil]];
 
 	SCPropertyDefinition *subInspectionAreaPropertyDef = [subInspectionAreaClassDef propertyDefinitionWithName:@"subArea"];
	subInspectionAreaPropertyDef.type = SCPropertyTypeObjectSelection;
	subInspectionAreaPropertyDef.attributes = [SCObjectSelectionAttributes attributesWithItemsEntityClassDefinition:subAreaClassDef withItemsTitlePropertyName:@"name" allowMultipleSelection:NO allowNoSelection:NO];

When that cell is displayed however via detailViewWillAppearForCell, I want to be able to filter the rows returned for the user, from that SubAreaType CoreData table. Is this possible somehow ? ? Thanks

Hi Phil, This is actually scheduled for our next release, and will be added to the beta version (just released here: www.sensiblecocoa.com/forum/announcement...0-beta-released.html) in about a week from now. Thanks!	tarekskr OFFLINE Administrator Posts: 2402 Karma: 72

Hi Phil, We've added a new property to SCObjectSelectionAttributes called "itemsPredicate". All you need to filter the selection items now is set this property to a valid NSPredicate instance. Please tell me if this works well for you. The new property is part of our STV 2.0 beta2 release, which I've just sent you a copy of.	tarekskr OFFLINE Administrator Posts: 2402 Karma: 72

Hi Tarek,

Is it possible to get access or set the predicate dynamically against the SCObjectSelectionAttributes and not when the class and property definitions are initially created ? Or do you have an example of its use ?

I have a list of subAreas, and the predicate is based on the current inspection area i.e.

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"forArea=%@", inspectionArea];

, which can only be evaluated at runtime.

Thanks
