Как выбрать контакт с ABPeoplePickerNavigationController в Swift?

Question

Как выбрать контакт с ABPeoplePickerNavigationController в Swift?

Я добавил ABPeoplePickerNavigationController в свой первый контроллер вида. Я хочу, чтобы при выборе контакта отображалась информация для отображения в другом контроллере вида, но я пытаюсь использовать свой код, и это не отображается никогда, Когда я нажимаю на контакт. Это только откроет контакт в родное приложение ABPeoplePickerNavigationController.

var people = ABPeoplePickerNavigationController()
var addressBook: ABAddressBookRef?

func extractABAddressBookRef(abRef: Unmanaged<ABAddressBookRef>!) -> ABAddressBookRef? {
    if let ab = abRef {
        self.view.addSubview(people.view)
        return Unmanaged<NSObject>.fromOpaque(ab.toOpaque()).takeUnretainedValue()
    }
    return nil
}

Я попробовал эту функцию

func peoplePickerNavigationController(peoplePicker: ABPeoplePickerNavigationController!,didSelectPerson person: ABRecordRef!) {

    var unmanagedEmails = ABRecordCopyValue(people, kABPersonEmailProperty)
    let emailObj: ABMultiValueRef = Unmanaged.fromOpaque(unmanagedEmails.toOpaque()).takeUnretainedValue() as NSObject as ABMultiValueRef

    var index = 0 as CFIndex

    var unmanagedEmail = ABMultiValueCopyValueAtIndex(emailObj, index)
    var emailAddress:String = Unmanaged.fromOpaque(unmanagedEmail.toOpaque()).takeUnretainedValue() as NSObject as String

    println(emailAddress)      
}

Спасибо!

Вот последний фреймворк для iOS 9-ContactsUI

Импорт ContactsUI
Соответствует CNContactPickerDelegate (нет обязательных методов)

Создайте объект выбора контактов и представьте его:

let peoplePicker = CNContactPickerViewController()

peoplePicker.delegate = self

self.presentViewController(peoplePicker, animated: true, completion: nil)

Отклонить CNContactPickerViewController в функции делегата contactPickerDidCancel

func contactPickerDidCancel(picker: CNContactPickerViewController) {
    picker.dismissViewControllerAnimated(true, completion: nil)
}

Вот как я получил доступ к имени контактов, номерам телефонов, меткам номеров телефонов и фотографиям использование функции делегата didSelectContact:

func contactPicker(picker: CNContactPickerViewController, didSelectContact contact: CNContact) {
//Dismiss the picker VC
picker.dismissViewControllerAnimated(true, completion: nil)
//See if the contact has multiple phone numbers
if contact.phoneNumbers.count > 1 {
    //If so we need the user to select which phone number we want them to use
    let multiplePhoneNumbersAlert = UIAlertController(title: "Which one?", message: "This contact has multiple phone numbers, which one did you want use?", preferredStyle: UIAlertControllerStyle.Alert)
    //Loop through all the phone numbers that we got back
    for number in contact.phoneNumbers {
        //Each object in the phone numbers array has a value property that is a CNPhoneNumber object, Make sure we can get that
        if let actualNumber = number.value as? CNPhoneNumber {
            //Get the label for the phone number
            var phoneNumberLabel = number.label
            //Strip off all the extra crap that comes through in that label
            phoneNumberLabel = phoneNumberLabel.stringByReplacingOccurrencesOfString("_", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
            phoneNumberLabel = phoneNumberLabel.stringByReplacingOccurrencesOfString("$", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
            phoneNumberLabel = phoneNumberLabel.stringByReplacingOccurrencesOfString("!", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
            phoneNumberLabel = phoneNumberLabel.stringByReplacingOccurrencesOfString("<", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
            phoneNumberLabel = phoneNumberLabel.stringByReplacingOccurrencesOfString(">", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
            //Create a title for the action for the UIAlertVC that we display to the user to pick phone numbers
            let actionTitle = phoneNumberLabel + " - " + actualNumber.stringValue
            //Create the alert action
            let numberAction = UIAlertAction(title: actionTitle, style: UIAlertActionStyle.Default, handler: { (theAction) -> Void in
                //Create an empty string for the contacts name

                    //If Not check for a last name
                    if contact.familyName == "" {
                        //If no last name set name to Unknown Name
                        nameToSave = "Unknown Name"
                    }else{

Пара мыслей:
Установили ли вы свойство peoplePickerDelegate контроллера выбора people? Если вы этого не сделаете, он не будет знать, чтобы попытаться вызвать эти методы в вашем классе. Таким образом:
people.peoplePickerDelegate = self
presentViewController(people, animated: true, completion: nil)
Ваш пример метода ссылается на people при вызове ABRecordCopyValue. Это ваш контроллер выбора. Я предполагаю, что вы хотели сослаться на person, ABRecordRef!, который был передан в качестве параметра.

Вы также можете убедиться, что у вас действительно есть адрес электронной почты. прежде чем пытаться получить к нему доступ. Вы можете использовать ABMultiValueGetCount.

Я также думаю, что вы можете также устранить это fromOpaque/toOpaque танцуй.

Это дает:
func peoplePickerNavigationController(peoplePicker: ABPeoplePickerNavigationController, didSelectPerson person: ABRecord) {
    let emails: ABMultiValueRef = ABRecordCopyValue(person, kABPersonEmailProperty).takeRetainedValue()
    if ABMultiValueGetCount(emails) > 0 {
        let index = 0 as CFIndex
        let emailAddress = ABMultiValueCopyValueAtIndex(emails, index).takeRetainedValue() as! String

        print(emailAddress)
    } else {
        print("No email address")
    }
}
Если вам также нужна поддержка iOS 7, Используйте:
func peoplePickerNavigationController(peoplePicker: ABPeoplePickerNavigationController, shouldContinueAfterSelectingPerson person: ABRecord, property: ABPropertyID, identifier: ABMultiValueIdentifier) -> Bool {
    let multiValue: ABMultiValueRef = ABRecordCopyValue(person, property).takeRetainedValue()
    let index = ABMultiValueGetIndexForIdentifier(multiValue, identifier)
    let email = ABMultiValueCopyValueAtIndex(multiValue, index).takeRetainedValue() as! String

    print("email = \(email)")

    peoplePicker.dismissViewControllerAnimated(true, completion: nil)

    return false
}
Однако вместо того, чтобы предполагать, что пользователю нужен только первый адрес электронной почты, вы можете позволить ему щелкнуть и выбрать один из возможных нескольких адресов электронной почты, которые были у контакта. Итак, во-первых, возможно, вы захотите устранить некоторые из "шум", сообщая сборщику, что вы хотите видеть только адреса электронной почты:
people.peoplePickerDelegate = self
people.displayedProperties = [NSNumber(int: kABPersonEmailProperty)]
presentViewController(people, animated: true, completion: nil)
А затем удалите предыдущий метод, который мы обсуждали, и вместо этого реализуйте:
func peoplePickerNavigationController(peoplePicker: ABPeoplePickerNavigationController!, didSelectPerson person: ABRecordRef!, property: ABPropertyID, identifier: ABMultiValueIdentifier) {
    let multiValue: ABMultiValueRef = ABRecordCopyValue(person, property).takeRetainedValue()
    let index = ABMultiValueGetIndexForIdentifier(multiValue, identifier)
    let email = ABMultiValueCopyValueAtIndex(multiValue, index).takeRetainedValue() as String

    println("email = \(email)")
}
И для поддержки iOS 7,0, вы бы добавили:
func peoplePickerNavigationController(peoplePicker: ABPeoplePickerNavigationController, shouldContinueAfterSelectingPerson person: ABRecord, property: ABPropertyID, identifier: ABMultiValueIdentifier) -> Bool {
    let multiValue: ABMultiValueRef = ABRecordCopyValue(person, property).takeRetainedValue()
    let index = ABMultiValueGetIndexForIdentifier(multiValue, identifier)
    let email = ABMultiValueCopyValueAtIndex(multiValue, index).takeRetainedValue() as! String

    print("email = \(email)")

    peoplePicker.dismissViewControllerAnimated(true, completion: nil)

    return false
}
Кстати, iOS 8 предлагает функцию для контроля того, включен ли контакт или нет. Поскольку вы поддерживаете iOS 7 и 8, вы хотели бы использовать это условно, например:
if people.respondsToSelector(Selector("predicateForEnablingPerson")) {
    people.predicateForEnablingPerson = NSPredicate(format: "emailAddresses.@count > 0")
}
Это дает пользователю визуальную индикацию есть ли даже адрес электронной почты для человека, и предотвращает их от выбора записи без адреса электронной почты.
Очевидно, что при использовании iOS 9 и более поздних версий вам следует отказаться от всего этого и использовать фреймворк ContactsUI, что еще больше упрощает код.
