I am trying to generate predicate editor templates for my Core Data entities. In my code I have the following:
NSEntityDescription *descrip = [NSEntityDescription entityForName:@"Person" inManagedObjectContext:managedObjectContext];
NSArray *templates = [NSPredicateEditorRowTemplate templatesWithAttributeKeyPaths:[NSArray arrayWithObjects:@"name", @"age", nil] inEntityDescription:descrip];
[ibPredicateEditor setRowTemplates: templates];
NSPredicate *p = [NSPredicate predicateWithFormat:@"name like 'John'"];
[ibPredicateEditor setObjectValue:p];
Printing out the contents of the templates array gives me the following:
<CFArray 0x1002d7400 [0x7fff70ff5f20]>{type = immutable, count = 2, values = (
0 : <NSPredicateEditorRowTemplate 0x10025c090: [name] [99, 4, 5, 8, 9] NSStringAttributeType>
1 : <NSPredicateEditorRowTemplate 0x1002d2dc0: [age] [4, 5, 0, 2, 1, 3] NSInteger16AttributeType>
)}
When this code executes I get the following on the console:
Warning - unable to find template matching predicate name LIKE "Worsley"
The interface for doing this looks extremely straight forward, so I can't seem to figure out what I am doing wrong. Any help would be greatly appreciated!
Cheers,
