Question

我在Swift的早期版本中编写了以下类。 Swift 2 编译器警告

iOS 9.0 中弃用

' kABPersonAddressStreetKey '：使用 CNPostalAddress.street

并发出错误

'找不到接受的“MKPlacemark”类型的初始值设定项类型的参数列表'（坐标：CLLocationCoordinate2D， addressDictionary：[String：String？]）'

我意识到需要选项才能解决错误，但无论我尝试什么似乎都无法解决问题。这是因为我是一个快速的新手，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
  }
}

Answer 1

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

}

Answer 2

您应该使用：

import Contacts代替import AddressBook。
CNPostalAddressStreetKey代替kABPersonAddressStreetKey。

Answer 3

在此提起雷达。今天得到了这样的答复：

Engineering已提供有关此问题的以下信息：请注意，您应该继续使用已弃用的密钥。

Answer 4

您需要将副标题转换为AnyObject，如下所示：

让addressDict = [String（kABPersonAddressStreetKey）：self.subtitle as！ AnyObject]

您的“func mapItem（） - ＆gt; MKMapItem {}”的完整代码将是：

func mapItem() -> MKMapItem {
    let addressDict = [String(kABPersonAddressStreetKey): self.subtitle as! AnyObject]
    let placemark = MKPlacemark(coordinate: self.coordinate, addressDictionary: addressDict)

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

    return mapItem
  }

在iOS 9.0中不推荐使用'kABPersonAddressStreetKey'：使用CNPostalAddress.street
