我已将其添加ABPeoplePickerNavigationController到我的第一个视图控制器中。我希望当我选择一个联系人时显示要在其他视图控制器中显示的信息,但我正在尝试使用我的代码,当我点击一个联系人时这不会显示。这只会将联系人打开到本机应用程序ABPeoplePickerNavigationController中。

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!

这是 iOS 9 的最新框架 - ContactsUI

  1. 导入联系人UI

  2. 符合CNContactPickerDelegate(不需要方法)

  3. 创建一个联系人选择器对象并呈现它:

    let peoplePicker = CNContactPickerViewController()
    
    peoplePicker.delegate = self
    
    self.presentViewController(peoplePicker, animated: true, completion: nil)
    
  4. 在contactPickerDidCancel委托函数中解除CNContactPickerViewController

    func contactPickerDidCancel(picker: CNContactPickerViewController) {
        picker.dismissViewControllerAnimated(true, completion: nil)
    }
    
  5. 以下是我使用 didSelectContact 委托函数访问联系人姓名、电话号码、电话号码标签和照片的方法:

    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

                    //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{

                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)

几个想法:

  1. 您是否设置了选择器控制器的peoplePickerDelegate属性people?如果你不这样做,它就不会知道尝试在你的类中调用这些方法。因此:

    people.peoplePickerDelegate = self
    presentViewController(people, animated: true, completion: nil)
    
  2. people当您调用时,您的示例方法正在引用ABRecordCopyValue。那是您的选择器控制器。我假设你的意思是引用personABRecordRef!作为参数传递的。

    您可能还想在尝试访问它之前确保您确实有一个电子邮件地址。您可以使用ABMultiValueGetCount.

    我也认为你也可以消除那个fromOpaque/toOpaque跳舞。

    这产生:

    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. 如果您也需要支持 iOS 7,请使用:

    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. 但是,您可能不会假设用户只想要第一个电子邮件地址,而是让他们点击并选择联系人可能拥有的多个电子邮件地址中的一个。因此,首先,您可能希望通过告诉选择器您只想查看电子邮件地址来消除一些“噪音”:

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

    然后,删除我们一直在讨论的先前方法,而是实现:

    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)")
    }
    

    为了支持 iOS 7,0,您还需要添加:

    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. 顺便说一句,iOS 8 提供了一个功能来控制联系人是否启用。由于您支持 iOS 7 和 8,因此您希望有条件地使用它,例如:

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

    这给用户视觉指示是否有个人的电子邮件地址,并防止他们选择没有电子邮件地址的条目。

显然,如果使用 iOS 9 及更高版本,您应该停用所有这些并使用ContactsUI框架,这进一步简化了代码。
