電子郵件CNContact as vCard

Question

是否可以通過電子郵件將CNMutableContact轉換爲電子名片？ 通過下面的代碼我創建CNMutableContact並將其保存到文檔目錄，但可以直接發送而不是保存它？我不需要保存它。

let contact = CNMutableContact() 
    contact.givenName = "John" 
    contact.familyName = "Doe" 
    contact.emailAddresses = [ 
     CNLabeledValue(label: CNLabelWork, value: "john.doe@abc.com") 
    ] 
    let data = try! CNContactVCardSerialization.data(with: [contact]) 
    let s = String(data: data, encoding: String.Encoding.utf8) 
    if let directoryURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first{ 
     let fileURL = directoryURL.appendingPathComponent("john.doe").appendingPathExtension("vcf") 
     try! data.write(to: fileURL, options: [.atomicWrite]) 
    }

請嘗試以下代碼發送聯繫人作爲電子郵件中的電子名片。

let contact = CNMutableContact() 
    contact.givenName = "John" 
    contact.familyName = "Doe" 
    contact.emailAddresses = [ 
     CNLabeledValue(label: CNLabelWork, value: "john.doe@abc.com") 
    ] 
    let data = try! CNContactVCardSerialization.data(with: [contact]) 

let mailComposer: MFMailComposeViewController = MFMailComposeViewController() 
      mailComposer.mailComposeDelegate = self 
      mailComposer.setSubject("emailsubject".localize()) 
      // mailComposer.setMessageBody("", isHTML: false) 
      mailComposer.addAttachmentData(data), mimeType: "text/vcf", fileName: "contacts.vcf") 
      self.present(mailComposer, animated: true, completion: nil)
