Swift iOS 8+中的通訊簿更改通知

Question

我試過下面的代碼，但沒有運氣。

if let addressBook = ABAddressBookCreateWithOptions(nil, nil) { 

    let ref = addressBook 
    let callback: @convention(c) (addressBookRef: ABAddressBookRef!, info: CFDictionaryRef!, context: UnsafeMutablePointer<Void>) -> Void = { 
     (addressBookRef, info, context) in 

     print("Address book editr ") 
    } 

    let addressBookChangeCallback = unsafeBitCast(callback, ABExternalChangeCallback.self) 
    ABAddressBookRegisterExternalChangeCallback(ref, addressBookChangeCallback, nil) 
} 

Answer 1

您可以添加NSNotifications以查找任何地址簿更改。要添加一個NSNotification你應該使用： -

NSNotificationCenter.defaultCenter().addObserver(self, selector: "addressBookDidChange:", name: CNContactStoreDidChangeNotification, object: nil) 

而對於去除NSNotification： -

NSNotificationCenter.defaultCenter().removeObserver(self, name: CNContactStoreDidChangeNotification, object: nil) 

最後加一個功能時的地址簿的變化： -

@objc func addressBookDidChange(notification: NSNotification){ 
    //Something You want to do 
} 

Answer 2

最新的API在迅速是：

NotificationCenter.default.addObserver(
      self, selector: #selector(addressBookDidChange), name: .CNContactStoreDidChange, object: nil)
