SwiftでABPeoplePickerNavigationControllerで連絡先を選択するにはどうすればよいですか？

Question

最初のビューコントローラにABPeoplePickerNavigationControllerを追加しました。連絡先を選択したときに他のビューコントローラーに表示する情報を表示したいのですが、コードを使用しようとしていますが、連絡先をクリックしても表示されません。これにより、連絡先がネイティブアプリABPeoplePickerNavigationControllerにのみ開かれます。

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
}

この機能を試しました

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)      
}

ありがとう！

Answer 1

いくつかの考え：

1. peoplePickerDelegateピッカーコントローラーのpeopleプロパティを設定しましたか？そうしないと、クラスでこれらのメソッドを呼び出そうとしてもわかりません。したがって：

   people.peoplePickerDelegate = self
   presentViewController(people, animated: true, completion: nil)
   

2. メソッドの例では、peopleを呼び出すときにABRecordCopyValueを参照しています。それがピッカーコントローラーです。パラメータとして渡されたABRecordRef!、personを参照するつもりだったと思います。

   また、メールアドレスにアクセスする前に、実際にメールアドレスがあることを確認することもできます。 ABMultiValueGetCountを使用できます。

   fromOpaque/toOpaqueダンスも排除できると思います。

   これにより、

   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")
       }
   }
   

3. IOS 7もサポートする必要がある場合は、次を使用します。

   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
   }
   

4. ただし、ユーザーが最初のメールアドレスしか必要としない場合は、代わりに、クリックして連絡先が持つ可能性のある複数のメールアドレスの1つを選択するようにしてください。したがって、最初に、ピッカーにメールアドレスのみを表示したいことを伝えることにより、「ノイズ」の一部を排除することができます。

   people.peoplePickerDelegate = self
   people.displayedProperties = [NSNumber(int: kABPersonEmailProperty)]
   presentViewController(people, animated: true, completion: nil)
   

   次に、これまで説明してきた以前のメソッドを削除し、代わりに実装します。

   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)")
   }
   

   また、iOS 7,0もサポートするために、次のように追加します。

   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
   }
   

5. ちなみに、iOS 8には、連絡先を有効にするかどうかを制御する機能があります。 iOS 7および8をサポートしているので、次のように条件付きで使用する必要があります。

   if people.respondsToSelector(Selector("predicateForEnablingPerson")) {
       people.predicateForEnablingPerson = NSPredicate(format: "emailAddresses.@count > 0")
   }
   

   これにより、ユーザーにメールアドレスが存在するかどうかをユーザーに視覚的に示し、メールアドレスのないエントリを選択できないようにします。

明らかに、iOS 9以降を使用している場合は、これらすべてを廃止し、ContactsUIフレームワークを使用する必要があります。これにより、コードがさらに簡素化されます。

Answer 2

こちらがiOS 9の最新フレームワークです-ContactsUI

1. contactsUIをインポートする

2. CNContactPickerDelegate に準拠（必要なメソッドはありません）

3. 連絡先ピッカーオブジェクトを作成して表示します。

   let peoplePicker = CNContactPickerViewController()
   
   peoplePicker.delegate = self
   
   self.presentViewController(peoplePicker, animated: true, completion: nil)
   

4. ContactPickerDidCancelデリゲート関数のCNContactPickerViewControllerを閉じます

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

5. 次に、didSelectContactデリゲート関数を使用して連絡先の名前、電話番号、電話番号ラベル、写真にアクセスする方法を示します。

   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
                   var nameToSave = ""
                   //See if we can get A frist name
                   if contact.givenName == "" {
                       //If Not check for a last name
                       if contact.familyName == "" {
                           //If no last name set name to Unknown Name
                           nameToSave = "Unknown Name"
                       }else{
                           nameToSave = contact.familyName
                       }
                   }else{
                       nameToSave = contact.givenName
                   }
   
                   // See if we can get image data
                   if let imageData = contact.imageData {
                       //If so create the image
                       let userImage = UIImage(data: imageData)
                   }
                   //Do what you need to do with your new contact information here!
                   //Get the string value of the phone number like this:

               //Add the action to the AlertController
               multiplePhoneNumbersAlert.addAction(numberAction)
           }
       }
       //Add a cancel action
       let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel, handler: { (theAction) -> Void in
