I'd like to key-value observe a property of an NSManagedObject. I
tried to register an observer (in the init: method of my app's
controller) using "addObserver:forKeyPath:options:" but it doesn't
work because the observation is lost as my object gets dealloc'ed soon
after I register as an observer. This is specified in the Core Data
documentation : "Core Data "owns" the life-cycle of managed objects.
[...] managed objects can be instantiated, destroyed, and resurrected
by the framework as it requires."
So how can I observe a Core Data object property and how can the
observation survive the multiple instantiations/desctructions of the
NSManagedObject?
