literal - ¿Cómo seleccionar un contacto con ABPeoplePickerNavigationController en Swift?

swift unicode character literal

Question

He añadido el ABPeoplePickerNavigationController en mi primer controlador de vista. Quiero que cuando seleccione un contacto muestre la información para mostrar en otro controlador de vista, pero estoy intentando usar mi código y esto no se muestra nunca cuando hago clic en un contacto. Esto solo abre el contacto en la aplicación nativa 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
}

Probé esta función

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)      
}

¡Gracias!

Aquí está el último marco para iOS 9 - ContactsUI

1. importar ContactsUI

2. Conforme con CNContactPickerDelegate (No se requieren métodos)

3. Crea un objeto selector de contactos y preséntalo:

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

4. Descarte el CNContactPickerViewController en la función de delegado contactPickerDidCancel

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

5. Aquí es cómo accedí al nombre de un contacto, números de teléfono, etiquetas de números de teléfono y foto usando la función de delegado 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
                   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)
               phoneNumberLabel = phoneNumberLabel.stringByReplacingOccurrencesOfString(">", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
   
               //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

                       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
           }

Answer 2

Un par de pensamientos:

1. ¿Ha establecido la propiedad peoplePickerDelegate del controlador del selector de people ? Si no lo hace, no sabrá intentar llamar a estos métodos en su clase. Así:

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

2. Su método de ejemplo es hacer referencia a people cuando llama a ABRecordCopyValue . Ese es el controlador de su selector. Supongo que ABRecordRef! hacer referencia a la person , ABRecordRef! Eso fue pasado como un parámetro.

   También es posible que desee asegurarse de que realmente tiene una dirección de correo electrónico antes de intentar acceder a ella. Puede utilizar ABMultiValueGetCount .

   También creo que también puedes eliminar eso de la danza de fromOpaque / toOpaque .

   Esto produce:

   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. Si también necesitas soportar iOS 7, usa:

   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. Sin embargo, en lugar de suponer que el usuario solo deseaba la primera dirección de correo electrónico, permítale que haga clic y elija una de las múltiples direcciones de correo electrónico posibles que tenía el contacto. Entonces, en primer lugar, es posible que desee eliminar parte del "ruido", indicando al selector que solo desea ver las direcciones de correo electrónico:

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

   Y luego, elimine el método anterior que hemos estado discutiendo y, en su lugar, implemente:

   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)")
   }

   Y para soportar iOS 7.0, también, agregarías:

   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. Por cierto, iOS 8 ofrece una función para controlar si un contacto está habilitado o no. Ya que está soportando iOS 7 y 8, querría emplear eso condicionalmente, como por ejemplo:

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

   Esto le da al usuario una indicación visual de si hay incluso una dirección de correo electrónico para el individuo, y le impide seleccionar una entrada sin dirección de correo electrónico.

Obviamente, si usa iOS 9 y versiones posteriores, debe retirar todo esto y usar el marco de ContactsUI , lo que simplifica aún más el código.
