Notify changes in property for Core Data?

Question

The user will be able to add or change some value (property in my model with Core Data) in one view, when the user switch to another view, I want to show the newly added/changed value with an animation.

Is there a way to get a notification that there has been a change or an update for a property with Core Data?

Answer 1

Have a look at implementing the class method keyPathsForValuesAffecting<key>
