ios - 'kABPersonAddressStreetKey' 在 iOS 9.0 : use CNPostalAddress. 街道中被弃用

Question

我用早期版本的 Swift 编写了以下类。 Swift 2 编译器警告

'kABPersonAddressStreetKey' 在 iOS 9.0 中被弃用:使用 CNPostalAddress.street

并报错

'Cannot find an initializer for type 'MKPlacemark' that accepts an argument list of type '(coordinate: CLLocationCoordinate2D, addressDictionary: [String : String?])'

我意识到需要可选值来解决错误，但无论我尝试什么，似乎都无法解决问题。这是因为我是 swift 的新手，我们将不胜感激。

import Foundation
import MapKit
import AddressBook

class Artwork: NSObject, MKAnnotation {
let title: String?
let locationName: String
let discipline: String
let coordinate: CLLocationCoordinate2D

init(title: String, locationName: String, discipline: String, coordinate: CLLocationCoordinate2D) {
    self.title = title
    self.locationName = locationName
    self.discipline = discipline
    self.coordinate = coordinate

    super.init()
}

var subtitle: String? {
    return locationName
}

// annotation callout info button opens this mapItem in Maps app
func mapItem() -> MKMapItem {
    let addressDictionary = [String(kABPersonAddressStreetKey): subtitle]
    let placemark = MKPlacemark(coordinate: coordinate, addressDictionary: addressDictionary)

    let mapItem = MKMapItem(placemark: placemark)
    mapItem.name = title

    return mapItem
  }
}

将 import AddressBook 替换为 import Contacts 并将 String(kABPersonAddressStreetKey) 替换为 String(CNPostalAddressStreetKey)

import Foundation
import MapKit
import Contacts

class Artwork: NSObject, MKAnnotation {
let title: String?
let locationName: String
let discipline: String
let coordinate: CLLocationCoordinate2D

init(title: String, locationName: String, discipline: String,       coordinate: CLLocationCoordinate2D) {
    self.title = title
    self.locationName = locationName
    self.discipline = discipline
    self.coordinate = coordinate

    super.init()
}

var subtitle: String? {
    return locationName
}

// annotation callout info button opens this mapItem in Maps app
func mapItem() -> MKMapItem {
    let addressDictionary = [String(CNPostalAddressStreetKey): self.subtitle!]
    let placemark = MKPlacemark(coordinate: coordinate, addressDictionary: addressDictionary)
    let mapItem = MKMapItem(placemark: placemark)
    mapItem.name = title

    return mapItem

}
