Answer 1

从 iOS 9 开始，您可以注册您的类(class)以观察CNContactStoreDidChangeNotification

NSNotificationCenter.defaultCenter().addObserver(
    self,
    selector: #selector(addressBookDidChange),
    name: NSNotification.Name.CNContactStoreDidChange,
    object: nil)

然后:

@objc func addressBookDidChange(notification: NSNotification){     
    //Handle event here...
}

如 Contacts Framework Reference 中所报告

After a save is successfully executed, the contact store posts a CNContactStoreDidChangeNotification notification to the default notification center. If you cache any Contacts framework objects you need to refetch those objects, either by their identifiers, or with the predicates that were used to originally fetch them, and then release the cached objects. Note that cached objects are stale, but not invalid.
