How to select a contact with ABPeoplePickerNavigationController in Swift? - 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 controller, but I'm trying use my code and this not show never when I click in a contact. This only open the contact into native app 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
}
I tried this function
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)
}
Thanks!

Here is the latest framework for iOS 9 - ContactsUI
import ContactsUI
Conform to the CNContactPickerDelegate (No required methods)
Create a contacts picker object and present it:
let peoplePicker = CNContactPickerViewController()
peoplePicker.delegate = self
self.presentViewController(peoplePicker, animated: true, completion: nil)
Dismiss the CNContactPickerViewController in the contactPickerDidCancel delegate function
func contactPickerDidCancel(picker: CNContactPickerViewController) {
picker.dismissViewControllerAnimated(true, completion: nil)
}
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)
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
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
}
}else{
//If there are no phone numbers associated with the contact I call a custom funciton I wrote that lets me display an alert Controller to the user
self.displayAlert("Missing info", message: "You have no phone numbers associated with this contact")
}
}
}

Answer 2

A couple of thoughts:
Have you set the peoplePickerDelegate property of the people picker controller? If you don't do that, it won't know to try to call these methods in your class. Thus:
people.peoplePickerDelegate = self
presentViewController(people, animated: true, completion: nil)
Your example method is referencing people when you call ABRecordCopyValue. That's your picker controller. I assume you meant to reference person, the ABRecordRef! that was passed as a parameter.
You might also want to make sure you actually have an email address before trying to access it. You can use ABMultiValueGetCount.
I also think you can also eliminate that fromOpaque/toOpaque dance.
This yields:
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")
}
}
If you need to support iOS 7, too, use:
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
}
You might, though, rather than assuming the user only wanted the first email address, instead, let them click through and pick one of the possible multiple email addresses the contact had. So, first, you might want to eliminate some of the "noise", by telling the picker that you only want to see email addresses:
people.peoplePickerDelegate = self
people.displayedProperties = [NSNumber(int: kABPersonEmailProperty)]
presentViewController(people, animated: true, completion: nil)
And then, remove the prior method we've been discussing, and instead implement:
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)")
}
And to support iOS 7,0, too, you'd add:
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
}
By the way, iOS 8 offers a feature to control whether a contact is enabled or not. Since you're supporting iOS 7 and 8, you'd want to employ that conditionally, such as:
if people.respondsToSelector(Selector("predicateForEnablingPerson")) {
people.predicateForEnablingPerson = NSPredicate(format: "emailAddresses.#count > 0")
}
This gives the user visual indication whether there is even an email address for the individual, and prevents them from selecting entry without email address.
Obviously, if using iOS 9 and later, you should retire all of this and use the ContactsUI framework, which simplifies the code further.
