How to select a contact with ABPeoplePickerNavigationController in Swift?

Question

I have added the ABPeoplePickerNavigationController into my first view controller. I want that when I select a contact show the info to show in other view controlle

Answer 1

Here is the latest framework for iOS 9 - ContactsUI

1. import ContactsUI

2. Conform to the CNContactPickerDelegate (No required methods)

3. Create a contacts picker object and present it:

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

4. Dismiss the CNContactPickerViewController in the contactPickerDidCancel delegate function

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

5. Here is how I Accessed a contacts name, phone numbers, phone number labels, and photo using the didSelectContact delegate function:

   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)
