我正在尝试使用与iOS Contacts应用程序集成的消息传递应用程序,以便用户可以直接从"联系人"通过应用程序发起消息.这在WWDC 2016会议240中有所涉及,但显然省略了一些细节.

在WWDC示例之后,我有:

• 将活动类型添加到应用程序Info.plist:

  <key>NSUserActivityTypes</key>
  <array>
          <string>INSendMessageIntent</string>
  </array>

• 实现application(_:continue:restorationHandler:)我的应用程序委托.

• 创建并捐赠了一种互动

  let activity = NSUserActivity(activityType: "com.example.message")  
  activity.title = "Send CB Test Message"  
  activity.expirationDate = Date.distantFuture  
  
  let recipient = INPerson( /* recipient with an email address in my Contacts database */ )  
  let sender = INPerson( /* me */ )        
  
  let intent = INSendMessageIntent(recipients: [recipient], content: nil, groupName: nil, serviceName: "CB Test Chat", sender: sender)  
  
  let response = INSendMessageIntentResponse(code: .success, userActivity: activity)
  let interaction = …

我需要联系,更改它并存储回来.

CNContactStore().unifiedContacts给我一个CNContact实例,但CNSaveRequest().update要求CNMutableContact.

如何将CNContact转换为CNMutableContact？

我想修改从a 的属性CNPostalAddress获得的a 的值。postalAddressCLPlacemark

由于CNPostalAddress具有不可变的属性，我想将其转换为CNMutablePostalAddress. 然而，似乎没有一种干净的方法可以做到这一点。我目前的方法是这样的：

extension CNPostalAddress {
    var mutableAddress: CNMutablePostalAddress {
        let address = CNMutablePostalAddress()

        address.city = city
        address.country = country
        address.postalCode = postalCode
        address.state = state
        address.street = street

        [...]

        return address
    }
}

有没有更好的方法来进行这种转换？
