电子邮件CNContact as vCard

Question

是否可以通过电子邮件将CNMutableContact转换为电子名片？ 通过下面的代码我创建CNMutableContact并将其保存到文档目录，但可以直接发送而不是保存它？我不需要保存它。

let contact = CNMutableContact() 
    contact.givenName = "John" 
    contact.familyName = "Doe" 
    contact.emailAddresses = [ 
     CNLabeledValue(label: CNLabelWork, value: "[email protected]") 
    ] 
    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]) 
    }

请尝试以下代码发送联系人作为电子邮件中的电子名片。

let contact = CNMutableContact() 
    contact.givenName = "John" 
    contact.familyName = "Doe" 
    contact.emailAddresses = [ 
     CNLabeledValue(label: CNLabelWork, value: "[email protected]") 
    ] 
    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)
