swift - 如何在 Swift 中使用 ABPeoplePickerNavigationController 选择联系人？

Question

我已将 ABPeoplePickerNavigationController 添加到我的第一个 View Controller 中。我希望当我选择一个联系人时显示要在其他 View Controller 中显示的信息，但我正在尝试使用我的代码并且当我单击联系人时这不会显示。这只会将联系人打开到 native 应用 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
}

我试过这个功能

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)      
}

谢谢!

Answer 1

这是 iOS 9 的最新框架 - ContactsUI

1. 导入联系人界面

2. 符合 CNContactPickerDelegate (不需要方法)

3. 创建一个联系人选择器对象并显示它:

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

4. 在 contactPickerDidCancel 委托(delegate)函数中关闭 CNContactPickerViewController

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

5. 以下是我如何使用 didSelectContact 委托(delegate)函数访问联系人姓名、电话号码、电话号码标签和照片:

   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:
                   actualNumber.stringValue  
               })
               //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
           //Cancel action completion
       })
       //Add the cancel action
       multiplePhoneNumbersAlert.addAction(cancelAction)
       //Present the ALert controller
       self.presentViewController(multiplePhoneNumbersAlert, animated: true, completion: nil)
   }else{
       //Make sure we have at least one phone number
       if contact.phoneNumbers.count > 0 {
           //If so get the CNPhoneNumber object from the first item in the array of phone numbers
           if let actualNumber = contact.phoneNumbers.first?.value as? CNPhoneNumber {
               //Get the label of the phone number
               var phoneNumberLabel = contact.phoneNumbers.first!.label
               //Strip out the stuff you don't need
               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)

               var nameToSave = ""
