I am trying to convert a Core Data app which uses garbage collection to ARC.
When I run the refactoring tool, I see issues like:
Semantic Issue: Type of property 'person' does not match type of accessor
'setPerson:'
The relevant declaration code:
@class ABPerson;
@interface XG2Student : NSManagedObject {
}
@property (nonatomic, retain) ABPerson * person;
- (ABPerson *)person;
- (void)setPerson:(ABPerson *)aPerson;
The relevant implementation:
@implementation XG2Student
@dynamic person;
/* custom getter omitted for brevity */
- (void)setPerson:(ABPerson *)aPerson {
[self willChangeValueForKey:XG2PersonKey];
[self setPrimitivePerson:aPerson];
[self didChangeValueForKey:XG2PersonKey];
self.personUID = [aPerson uniqueId]; // this is the value that is persisted
}
All properties with this issue are Core Data non-standard persistent attributes
and their custom setter methods follow the 'Immediate-Update Set Accessor'
pattern described in the section "Non-Standard Persistent Attributes" of "Core
Data Programming Guide".
Maybe I am missing something obvious but I don't see how the setPerson: method
doesn't match the property declaration.
Any help would be greatly appreciated.
Thanks,
Sean
