我已将ABPeoplePickerNavigationController添加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，但是我尝试使用我的代码，这在我点击联系人时不会显示。这只会将联系人打开到原生应用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！

有几点想法：
您是否设置了peoplePickerDelegate选取器控制器的people属性？如果你不这样做，它将不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)
当您致电people时，您的示例方法正在引用ABRecordCopyValue。那是你的选择控制器。我假设您打算引用person，即作为参数传递的ABRecordRef!。
您可能还想确保在尝试访问之前确实拥有电子邮件地址。您可以使用ABMultiValueGetCount。
我还认为你也可以消除fromOpaque / toOpaque舞蹈。
这会产生：
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")
}
}
如果您还需要支持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
}
但是，您可能不是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的多个电子邮件地址之一。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，而不是实现：
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
}
顺便说一句，iOS 8提供了一项控制是否启用联系人的功能。由于您支持iOS 7和8，因此您需要有条件地使用它，例如：
if people.respondsToSelector(Selector("predicateForEnablingPerson")) {
people.predicateForEnablingPerson = NSPredicate(format: "emailAddresses.@count > 0")
}
这使用户可以看到是否有个人的电子邮件地址，并阻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，这将进一步简化代码。

这是iOS 9的最新框架 - ContactsUI
导入ContactsUI
符合CNContactPickerDelegate（无需方法）
创建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)
在contactPickerDidCancel委托函数中解除CNContactPickerViewController
func contactPickerDidCancel(picker: CNContactPickerViewController) {
picker.dismissViewControllerAnimated(true, completion: nil)
}
以下是我使用didSelectContact委托功能访问联系人姓名，电话号码，电话号码标签和照片的方式：
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)

}
}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")
}
}
