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 的一部分协议(protocol)，每当用户点击 ABPersonViewController 中的项目时调用, 这样用户选择的任何信息都将被复制到 [String : String]字典使得属性名称将成为属性值的键:[..."kABPersonFirstNameProperty" : "Alexander"...] ， 说。

我还想避免使用开关或一长串条件来测试某个属性是这个还是那个；我宁愿尽可能笼统地处理它——我只尝试两种不同的情况:属性是单值还是多值。如果它是一个多值，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?)"...] .

经过数小时搜索 Apple Developer Library 和相关的 SO 问题(我知道这很可悲)，这就是我所拥有的:

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

}

我可以看出缺少了很多部分——是否有可能将其浓缩成一本字典？

最佳答案

以 vadian 的回答为起点，我编写了以下内容，它将收集并复制到字典中几乎所有用户可以选择的信息(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:将标签没有指定键的电话号码存储为 kAB_Label s，例如，它还没有采用电子邮件地址的标签。

与 s自类型 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
}

拜托，任何人都可以随意复制其中的任何/所有部分，这将有所帮助。
