ios - 如何从 iOS 中的联系人中提取姓名？

Question

我已经从通讯录中提取了一个联系人

现在我需要在同一 View Controller 中向 TextView UI 显示名称。

如何从 ABRecord 中提取名称？

这是我的代码。

@IBAction func addContact(sender: AnyObject) {
    var peoplePicker = ABPeoplePickerNavigationController()
    peoplePicker.peoplePickerDelegate = self
    self.presentViewController(peoplePicker, animated: true, completion: nil)

}

func peoplePickerNavigationControllerDidCancel(peoplePicker: ABPeoplePickerNavigationController!) {
    dismissViewControllerAnimated(true, completion: nil)
}


func peoplePickerNavigationController(peoplePicker: ABPeoplePickerNavigationController!, didSelectPerson person: ABRecord!) {

    var name : String! = ABRecordCopyCompositeName(person)
}

这里函数 ABRecordCopyCompositeName 返回非托管我不能强制转换为字符串。它说不可兑换。

我是 iOS 开发新手。请帮忙。

使用 takeUnretainedValue() 和 takeRetainedValue() 获取 CFString 对象并将其转换为 NSString

func peoplePickerNavigationController(peoplePicker: ABPeoplePickerNavigationController!, didSelectPerson person: ABRecord!) {
    let nameCFString : CFString = ABRecordCopyCompositeName(person).takeRetainedValue()
    let name : NSString = nameCFString as NSString
}
