swiftを使用してVCardからデータを取り出す方法

Question

QRコードスキャンを行っています。以下のスウィフトコードを使用すると、QRコードのデータがコンソールに印刷されます。

import UIKit 
import AVFoundation 

class ViewController: UIViewController, AVCaptureMetadataOutputObjectsDelegate 
{ 
    let session = AVCaptureSession() 
    @IBOutlet weak var square: UIImageView! 
    var video = AVCaptureVideoPreviewLayer() 

    override func viewDidLoad() 
    { 

     super.viewDidLoad() 
     // Do any additional setup after loading the view, typically from a nib. 


    } 

    func captureOutput(_ captureOutput: AVCaptureOutput!, didOutputMetadataObjects metadataObjects: [Any]!, from connection: AVCaptureConnection!) { 

     if metadataObjects != nil && metadataObjects.count != 0 
     { 
      if let object = metadataObjects[0] as? AVMetadataMachineReadableCodeObject 
      { 
       if object.type == AVMetadataObjectTypeQRCode 
       { 
        print(object.stringValue) 

        let alert = UIAlertController(title: "QR Code", message: object.stringValue, preferredStyle: .alert) 
        alert.addAction(UIAlertAction(title: "Okey", style: .default, handler: nil)) 
        /* alert.addAction(UIAlertAction(title: "Copy", style: .default, handler: { (nil) in 
         UIPasteboard.general.string = object.stringValue 
        })) 
       */ 
        present(alert, animated: true, completion: nil) 

        if metadataObjects.count > 0 
        { 
         print("-------------------------------------------------") 
         self.session.stopRunning() 

        } 

       } 
      } 
     } 
    } 

    @IBAction func startButton(_ sender: Any) 
    { 
     // Creating session 
     // let session = AVCaptureSession() 

     // Define capture device 
     let captureDevice = AVCaptureDevice.defaultDevice(withMediaType: AVMediaTypeVideo) 

     do { 
      let input = try AVCaptureDeviceInput(device: captureDevice) 
      session.addInput(input) 
     } catch { 
      print("Error") 
     } 

     let output = AVCaptureMetadataOutput() 
     session.addOutput(output) 

     output.setMetadataObjectsDelegate(self, queue: DispatchQueue.main) 

     output.metadataObjectTypes = [AVMetadataObjectTypeQRCode] 

     video = AVCaptureVideoPreviewLayer(session: session) 
     video.frame = view.layer.bounds 
     view.layer.addSublayer(video) 
     self.view.bringSubview(toFront: square) 
     session.startRunning()   
    } 

    override func didReceiveMemoryWarning() 
    { 
     super.didReceiveMemoryWarning() 
     // Dispose of any resources that can be recreated. 
    } 
} 

OUTPUT：

BEGIN:VCARD 
VERSION:2.1 
FN:John Peter 
N:Peter;John 
TITLE:Admin 
TEL;CELL:+91 431 524 2345 
TEL;WORK;VOICE:+91 436 542 8374

END:VCARD 

今私は、どのようにA等の姓、名、電子メールID、携帯電話番号を、得るようなものは、具体的にvCard形式でデータを取得している何をしたいですこれに先立って同様の質問がされていますが、それは客観的なものでした。私はこの迅速な方法を知らない3.事前に感謝します。

Answer 1

ここに私が使用したプレイグラウンドのサンプルコードがあります。それは最高ではないですが、あなたはアイデアを得るでしょう：CNContactVCardSerialization.contacts(with: data)から

import UIKit 
import Contacts 

var str = "BEGIN:VCARD \n" + 
"VERSION:2.1 \n" + 
"FN:John Peter \n" + 
"N:Peter;John \n" + 
"TITLE:Admin \n" + 
"TEL;CELL:+91 431 524 2345 \n" + 
"TEL;WORK;VOICE:+91 436 542 8374 \n" + 
"EMAIL;WORK;INTERNET:John@ommail.in \n" + 
"URL:www.facebook.com \n" + 
"ADR;WORK:;;423 ofce sales Center;Newark;DE;3243;USA \n" + 
"ORG:xxx Private limited \n" + 
"END:VCARD" 

if let data = str.data(using: .utf8) { 
    let contacts = try CNContactVCardSerialization.contacts(with: data) 
    let contact = contacts.first 
    print("\(String(describing: contact?.familyName))") 
} 

出力はCNContact（reference）の配列です。ここで
