Instance Property

weakRelatedUniqueIdentifier

For activities, the unique identifier for the item to which the activity is related, but not linked.

Declaration

@property(copy) NSString *weakRelatedUniqueIdentifier;

Discussion

Unlike the similar relatedUniqueIdentifier property, this property does not link the lifetime of the item to the lifetime of the activity. In particular, deleting the item does not delete the activity.
