//返回用户手机通讯录中所有联系人的手机号
func phoneNumbersFromContacts() throws -> [String]{

    //获取授权状态， 如果没有授权，那么请求授权
    let status: CNAuthorizationStatus = CNContactStore.authorizationStatusForEntityType(CNEntityType.Contacts)
    if status == CNAuthorizationStatus.NotDetermined{
        // 创建CNContactStore对象, 并请求授权
        let store = CNContactStore()
        store.requestAccessForEntityType(.Contacts, completionHandler: { (granted: Bool, error:  NSError?) -> Void in
            if error != nil {
                return
            }
            
            if granted{
                print("访问通讯录授权成功")

    //姓，名，号码
    let keys = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey]
    let request = CNContactFetchRequest(keysToFetch: keys)
    
    //请求所有联系人
    let store = CNContactStore()
    try store.enumerateContactsWithFetchRequest(request) { (contact:CNContact, stop:UnsafeMutablePointer<ObjCBool>) -> Void in
        
        for value in contact.phoneNumbers{
            if value.label == "_$!<Mobile>!$_"{
                let phoneNum = value.value as! CNPhoneNumber
                phoneNumbers.append(phoneNum.stringValue)
            }
        }
    }

    return phoneNumbers
