iPhone: Comment obtenir chaque élément du code QR vCard?

Question

Je développe une application simple qui est utilisée pour lire le code QR vCard et afficher les détails des informations de contact dans le code QR vCard. Je suis capable de scanner la carte de visite et obtenir les détails sur le contact comme suit

BEGIN:VCARD 
VERSION:2.1 
N:XX;XXXXXXXX 
FN:XXXXXXXXX XX 
TEL;WORK;VOICE:91999999999 
EMAIL;WORK;INTERNET:sac@gmail.com 
END:VCARD 

Mais je dois analyser chaque élément en elle. Comment analyser les détails et quelles sont les façons d'analyser?

Answer 1

Les points de documentation à cette méthode:

- (void) imagePickerController: (UIImagePickerController*) reader 
didFinishPickingMediaWithInfo: (NSDictionary*) info 
{ 
    id<NSFastEnumeration> results = [info objectForKey: ZBarReaderControllerResults]; 

    ZBarSymbol *symbol = nil; 

    for(symbol in results){ 

     NSString *upcString = symbol.data; 

     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Scanned UPC" message:[NSString stringWithFormat:@"The UPC read was: %@", upcString] delegate:self cancelButtonTitle:nil otherButtonTitles:@"Ok", nil]; 

     [alert show]; 

     [reader dismissModalViewControllerAnimated: YES];  
    }  

}

je voudrais d'abord voir ce qu'il retourne peut-être essayer en boucle le dictionnaire des données supplémentaires

Answer 2

vous pouvez utiliser l'encodeur de QRCode

Encoder

Eh bien, il est assez long que cette question est posée. Mais répondre maintenant pourrait aussi aider quelqu'un à naviguer sur cette page. Vous pouvez utiliser la méthode ci-dessous comme référence pour analyser les données VCF.

NSString *str = [NSString stringWithString:response.vcfString]; 
    NSArray *subStrings = [str componentsSeparatedByCharactersInSet:[NSCharacterSet  characterSetWithCharactersInString:@"\n"]]; 
    NSArray *getData = [[NSArray alloc]init]; 

    NSString *arr = @""; 

    for (int i=0;i<[subStrings count];i++) 
    { 
     arr = [subStrings objectAtIndex:i]; 

     NSArray *abc = [arr componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@";"]]; 

     if([[abc objectAtIndex:0] isEqualToString:@"FN"]) 
     { 
      getData=[[abc objectAtIndex:1] componentsSeparatedByCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@":"] ]; 

      if([getData count] > 1) 
      fullName = [getData objectAtIndex:1]; 
     } 
     else if([[abc objectAtIndex:0] isEqualToString:@"N"]) 
     { 
      getData=[[abc objectAtIndex:1] componentsSeparatedByCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@":"]]; 

      if([getData count] > 1) 
      lastName = [getData objectAtIndex:1]; 
      FirstName = [abc objectAtIndex:2]; 
     } 
     else if([[abc objectAtIndex:0] isEqualToString:@"TITLE"]) 
     { 
      getData=[[abc objectAtIndex:1] componentsSeparatedByCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@":"]]; 

      if([getData count] > 1) 
      title = [getData objectAtIndex:1]; 
     } 
     else if([[abc objectAtIndex:0] isEqualToString:@"TEL"]) 
     { 
      NSMutableDictionary *dict = [[NSMutableDictionary alloc] init]; 
      if([abc count] == 3) 
      { 
       getData=[[abc objectAtIndex:2] componentsSeparatedByCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@":"]]; 

       if([[abc objectAtIndex:1] isEqualToString:@"WORK"]) 
       { 
        if([getData count] > 1) 
         [dict setObject:[getData objectAtIndex:1] forKey:@"Tel"]; 
       } 
       else if([[abc objectAtIndex:1] isEqualToString:@"CELL"]) 
       { 
        if([getData count] > 1)

       } 
      } 
      else if([abc count] == 4) 
      { 
       getData=[[abc objectAtIndex:3] componentsSeparatedByCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@":"]]; 

       if([[abc objectAtIndex:1] isEqualToString:@"WORK"] && [[abc objectAtIndex:2] isEqualToString:@"FAX"]) 
       { 
        if([getData count] > 1) 
         [dict setObject:[getData objectAtIndex:1] forKey:@"Tel"]; 
       } 
      } 
      else

       } 
      } 
      [_telList addObject:dict]; 
     } 
     else if([[abc objectAtIndex:0] isEqualToString:@"EMAIL"]) 
     { 
      NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];

       if([[abc objectAtIndex:1] isEqualToString:@"WORK"]) 
       {

      } 
      else 
      {

    NSLog(@"Details: \nFull Name - %@\nLast Name - %@\nFirst Name - %@\ntitle - %@\nEmail - %@\norg - %@\nAddress - %@\nUrl - %@", fullName,lastName,FirstName,title,[[_emailList valueForKey:@"description"] componentsJoinedByString:@""],[_orgList description],[_addrList description],[_urlList description]);

Vous pouvez utiliser CNContactVCardSerialization pour obtenir CNContact objet à partir des données

import Contacts 
    if let data = str.data(using: .utf8) { 
     do { 
      let contacts = try CNContactVCardSerialization.contacts(with: data) 
      let contact = contacts.first 
      print("\(String(describing: contact?.familyName))") 
      return contact 
     } catch { 
      print("Contact Error: \(error.localizedDescription)") 
     } 
    }
