在iOS 9.0中已经不推荐使用’kABPersonAddressStreetKey’：使用CNPostalAddress.street

我有一个早期版本的 Swift写下面的类. Swift 2编译器警告

并给出错误

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

我意识到可选的是解决错误,但是我尝试的似乎并不能解决问题.这是因为我是一个新手快速,任何帮助将不胜感激.

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
  }
}

解决方法

用导入联系人替换导入AddressBook,并用String(CNPostalAddressStreetKey)替换String(kABPersonAddressStreetKey)

import Foundation
import MapKit
import Contacts
 
class Artwork: NSObject,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
 
}
