如何从iOS中的联系人中提取姓名？

Question

我已从地址簿中找到了联系人

现在我需要在同一个视图控制器中显示文本视图UI的名称。

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unmanaged我不能强制转换为String。它说不可转换。

我是iOS开发新手。请帮忙。

Answer 1

使用takeUnretainedValue（）和takeRetainedValue（）获取CFString对象并将其强制转换为NSString

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

您还可以查看KBContactsSelection，它允许您搜索和选择多个联系人，并且可以使用优雅Builder Pattern轻松自定义。
