在Xcode 6中从核心数据数据模型创建NSManagedObject子类

Question

I've got two entities in a Core Data Data Model. There is a one to many relationship between them. When I navigate to Editor --> Create NSManagedObject Subclass... , my models are generated but I do not get strongly typed method signatures like - (void)addPhotosObject:(NSManagedObject *)value; on the many side of the relationship.

According to what I've read, in Xcode 5 at least, this is because the class on the one side of the relationship was created first so the class on the many side of the relationship does not yet exist. The suggestions I see say to to simply Create NSManagedObject Subclass... again and the method should generate methods with strongly typed classes but the method signatures are not changing to strongly type.

Is there a trick to getting strongly typed method signatures?

Answer 1

After deleting the NSManagedObject subclasses that were initially created by Create NSManagedObject Subclass... and simply re-generating them by selecting Create NSManagedObject Subclass... again, the method signatures ended up strongly typed which gave me a Photo as a parameter like this - (void)addPhotosObject:(Photo *)value; instead of an NSManagedObject .
