Swift：将用户在 ABPersonViewController 中选择的信息复制到字典

Question

我正在尝试实现func personViewController(personViewController: ABPersonViewController!, shouldPerformDefaultActionForPerson person: ABRecord!, property property: ABPropertyID, identifier valueIdentifier: ABMultiValueIdentifier) -> Bool 函数，它是ABPersonViewControllerDelegate 协议的一部分，只要用户点击ABPersonViewController 中的项目就会被调用，这样用户选择的任何信息都将被复制到[String : String] 字典，这样属性名称将成为属性值的键：[..."kABPersonFirstNameProperty" : "Alexander"...]，比如说。

我还想避免一个开关或一长串条件测试一个属性是这个还是那个；我宁愿尽可能一般地处理它——我只尝试两种不同的情况：属性是单值还是多值。如果它是多值，我想复制所有可用的信息。

例如，如果用户点击地址，结果可能是这样的：[..."kABPersonAddressStreetKey" : "1 Infinite Loop", "kABPersonAddressCityKey" : "Cupertino" , "kABPersonAddressStateKey", "California (or CA?)"...]。

这就是我所拥有的，经过几个小时的搜索苹果开发者库和相关的 SO 问题（可悲，我知道）：

func personViewController(personViewController: ABPersonViewController!,
    shouldPerformDefaultActionForPerson person: ABRecord!,
    property property: ABPropertyID,
    identifier valueIdentifier: ABMultiValueIdentifier) -> Bool {

    s["kABPersonFirstNameProperty"] = ABRecordCopyValue(person, kABPersonFirstNameProperty) as! String //the name can't actually be selected by the user, but I want to capture it anyway
    s["kABPersonLastNameProperty"] = ABRecordCopyValue(person, kABPersonLastNameProperty) as! String

    if valueIdentifier == 0 { //property is a single property, not a multivalue property

        let record = ABRecordCopyValue(person, property)
        s[property as! String!] = record as! String

    } else { //property is an ABMultiValue

        let multiRecord = ABRecordCopyValue(person, property) as! ABMultiValueRef
        s[property as! String] = ABMultiValueGetIndexForIdentifier(multiRecord, valueIdentifier)

    }

    return false

}

我可以看出有很多片段丢失了——甚至可以将其浓缩成字典吗？

在此先感谢（以及 100 声望提供完整、正确答案的人）。

恐怕没有通用的方法可以从 AddressBook 中检索信息，因为有太多不同的集合和属性类型。

这是在用户点击地址字段时获取first name、last name 和address 信息的示例。

假设字典s被声明为

var s = Dictionary<String, AnyObject>()

 func personViewController(personViewController: ABPersonViewController!, shouldPerformDefaultActionForPerson person: ABRecord!, property: ABPropertyID, identifier: ABMultiValueIdentifier) -> Bool {

    addPropertyForKey("FirstName", person : person, property: kABPersonFirstNameProperty)
    addPropertyForKey("LastName", person : person, property: kABPersonLastNameProperty)

    if (property == kABPersonAddressProperty) {
      let multiRecord : ABMultiValueRef = ABRecordCopyValue(person, property).takeUnretainedValue()
      let index = ABMultiValueGetIndexForIdentifier(multiRecord, identifier)
      let addressRecord :AnyObject = ABMultiValueCopyValueAtIndex(multiRecord, index).takeUnretainedValue()
      addValuesFromRecord(addressRecord, forKeys:["Street", "City", "State", "ZIP", "Country", "CountryCode"])

      println(s)
    }

    return false
  }

  func addPropertyForKey(key : String, person: ABRecord, property : ABPropertyID)
  {
    let value : AnyObject = ABRecordCopyValue(person, property).takeUnretainedValue()
    s[key] = value
  }

  func addValuesFromRecord(record : AnyObject,  forKeys keys : [String])
  {
    for key in keys {
      if let value : AnyObject = record[key] {
        s[key] = value
      }
    }
  }

为了尽可能通用，所有值都声明为AnyObject

以 vadian 的回答为起点，我编译了以下内容，它将收集用户可以选择的几乎所有信息并将其复制到字典中（以及一些用户无法点击的信息——名字、姓氏名称、组织——自动）。

这是一项正在进行的工作，随着我继续添加对更多属性的支持，我将对其进行更新，但目前它适用于名字、姓氏、电子邮件、电话号码、地址和一些社交资料。

在某些情况下，我不得不使用间接方法：例如，将标签没有指定键的电话号码存储为kAB_Labels，并且它还没有使用电子邮件地址的标签。

s 的类型为 Dictionary<String, AnyObject>，这里是：

func personViewController(personViewController: ABPersonViewController!, shouldPerformDefaultActionForPerson person: ABRecord!, property: ABPropertyID, identifier: ABMultiValueIdentifier) -> Bool {

    addPropertyForKey("kABPersonFirstNameProperty", person : person, property: kABPersonFirstNameProperty)
    addPropertyForKey("kABPersonLastNameProperty", person : person, property: kABPersonLastNameProperty)
    addPropertyForKey("kABPersonOrganizationProperty", person: person, property: kABPersonOrganizationProperty)

    if (property == kABPersonAddressProperty) {
        let multiRecord : ABMultiValueRef = ABRecordCopyValue(person, property).takeUnretainedValue()
        let index = ABMultiValueGetIndexForIdentifier(multiRecord, identifier)
        let addressRecord :AnyObject = ABMultiValueCopyValueAtIndex(multiRecord, index).takeUnretainedValue()
        addValuesFromRecord(addressRecord, forKeys:["Street", "City", "State", "ZIP", "Country", "CountryCode"])

    }

    if (property == kABPersonEmailProperty) {

        let multiRecord: ABMultiValueRef = ABRecordCopyValue(person, property).takeUnretainedValue()
        let index = ABMultiValueGetIndexForIdentifier(multiRecord, identifier)
        let email = ABMultiValueCopyValueAtIndex(multiRecord, index).takeUnretainedValue() as! String

        if (s["kABPersonEmailProperty(1)"] == nil) {

            s["kABPersonEmailProperty(1)"] = email

        } else {

            s["kABPersonEmailProperty(2)"] = email

        }

    }

    if (property == kABPersonSocialProfileProperty) {

        let multiRecord: ABMultiValueRef = ABRecordCopyValue(person, property).takeUnretainedValue()
        let index = ABMultiValueGetIndexForIdentifier(multiRecord, identifier)
        let profile = ABMultiValueCopyValueAtIndex(multiRecord, index).takeUnretainedValue()
        let profileType = profile["service"] as! String
        let profileName = profile["username"] as! String

        switch profileType {
            case "facebook" : s["kABPersonSocialProfileServiceFacebook"] = profileName
            case  "twitter" : s["kABPersonSocialProfileServiceTwitter"] = profileName
            case "sinaweibo": s["kABPersonSocialProfileServiceSinaWeibo"] = profileName
            default: break
        }



    }

    if (property == kABPersonPhoneProperty) {

        let multiRecord : ABMultiValueRef = ABRecordCopyValue(person, property).takeUnretainedValue()
        let index = ABMultiValueGetIndexForIdentifier(multiRecord, identifier)
        let number = ABMultiValueCopyValueAtIndex(multiRecord, index).takeUnretainedValue() as! String

        let locLabel: CFStringRef = (ABMultiValueCopyLabelAtIndex(multiRecord, index) != nil) ? ABMultiValueCopyLabelAtIndex(multiRecord, index).takeUnretainedValue() as CFStringRef : ""
        let customLabel = String (stringInterpolationSegment: ABAddressBookCopyLocalizedLabel(locLabel))

        var cfStr:CFTypeRef = locLabel
        var nsTypeString = cfStr as! NSString
        var a:String = nsTypeString as String

        var b = a

        if (a.rangeOfString("_$!<") != nil) {

            b = a.substringFromIndex(a.rangeOfString("_$!<")!.endIndex)

            b = b.substringToIndex(b.rangeOfString(">!$_")!.startIndex)

        }

        switch b {

        case "Mobile" : s["kABPersonPhoneMobileLabel"] = number
        case "iPhone" : s["kABPersonPhoneIPhoneLabel"] = number
        case "Main" : s["kABPersonPhoneMainLabel"] = number
        case "Home" : s["kABHomeLabel"] = number
        case "Work" : s["kABWorkLabel"] = number
        case "Other" : s["kABOtherLabel"] = number
        default: break

        }

    }

    println(s)

    return false
}

请，任何人都可以随意复制它的任何/所有部分，这会有所帮助。
