iPhone: Как получить каждый элемент с QR-кода vCard?

Question

Я разрабатываю одно простое приложение, которое используется для чтения QR-кода vCard и отображения информации о контактной информации в QR-код vCard. Я могу сканировать визитную карточку и получить подробную информацию о контакте следующим

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

Но мне нужно разобрать каждый элемент в нем. Как разбирать детали и каковы способы анализа?

Answer 1

Точка документации к этому методу:

- (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];  
    }  

}

я бы первым увидеть, что она возвращает, может попытаться зацикливанием словаря для дополнительных данных

вы можете использовать энкодер из QRCode

Encoder

Ну, это довольно долгое время, когда задается этот вопрос. Но ответ теперь может также помочь кому-то, кто находится на этой странице. Вы можете использовать приведенный ниже метод для ссылки для анализа данных 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) 
         [dict setObject:[getData objectAtIndex:1] forKey:@"Tel"]; 
       } 
      } 
      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 
      {

       { 
        if([getData count] > 1) 
         [dict setObject:[getData objectAtIndex:1] forKey:@"Tel"]; 
       } 
      } 
      [_telList addObject:dict]; 
     } 
     else if([[abc objectAtIndex:0] isEqualToString:@"EMAIL"]) 
     { 
      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:@"Email"]; 
       } 
      } 
      else 
      { 
       getData=[[abc objectAtIndex:1] componentsSeparatedByCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@":"]]; 

       if([getData count] > 1)

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

      if([abc count] == 5) 
      { 
       getData=[[abc objectAtIndex:2] componentsSeparatedByCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@":"]]; 

       if([[abc objectAtIndex:1] isEqualToString:@"WORK"]) 
       { 
        NSString *orgStr = @"";

        [dict setObject:[orgStr stringByAppendingString:[abc objectAtIndex:4]] forKey:@"Org"]; 
       } 
      } 
      else 
      { 
       getData=[[abc objectAtIndex:1] componentsSeparatedByCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@":"]];

    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]);

Вы можете использовать CNContactVCardSerialization получить CNContact объект из данных

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)") 
     } 
    }
