Question

und ich möchte Werte daraus erhalten.

String

Methode

+ (void) showCurrentHistory:(NSString *) historyString { 

    NSString* processed = [historyString stringByReplacingOccurrencesOfString:@"\\\"" withString:@"\""]; 

    NSString* withotExtras = [[processed substringFromIndex:1] substringToIndex:[processed length] - 2]; 
    NSData *data = [[NSData alloc] initWithBytes:[withotExtras UTF8String] length:withotExtras.length]; 
    NSError *error; 

    NSMutableArray* jsonArray = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error]; 

    for (NSDictionary *dic in jsonArray) { 
     NSString *VisitorId   = [dic objectForKey:@"VisitorId"]; 
     NSString *VisitorSignalId = [dic objectForKey:@"VisitorSignalId"]; 
     NSString *Type    = [dic objectForKey:@"Type"]; 
     NSString *Messagetext  = [dic objectForKey:@"Messagetext"]; 
     NSString *MessageType  = [dic objectForKey:@"MessageType"]; 
     NSString *MessageTime  = [dic objectForKey:@"MessageTime"]; 
     NSString *Image    = [dic objectForKey:@"Image"]; 
     NSString *FileUploadDetails = [dic objectForKey:@"FileUploadDetails"]; 
     NSString *FirstOperatorName = [dic objectForKey:@"FirstOperatorName"]; 
     NSString *Rating   = [dic objectForKey:@"Rating"]; 

     NSLog(@"----------------------- Current Chat History --------------------------------"); 
     NSLog(@"VisitorId   : %@" , VisitorId); 
     NSLog(@"VisitorSignalId  : %@" , VisitorSignalId); 
     NSLog(@"Type    : %@" , Type); 
     NSLog(@"Messagetext   : %@" , Messagetext); 
     NSLog(@"MessageType   : %@" , MessageType); 
     NSLog(@"MessageTime   : %@" , MessageTime); 
     NSLog(@"Image    : %@" , Image); 
     NSLog(@"FileUploadDetails : %@" , FileUploadDetails); 
     NSLog(@"FirstOperatorName : %@" , FirstOperatorName); 
     NSLog(@"Rating    : %@" , Rating); 
     NSLog(@"------------------------------------------------------------------------------"); 

     MessageItemObject *item = [[MessageItemObject alloc] init]; 
     [item setVisitorId:VisitorId]; 
     [item setVisitorSignalId:VisitorSignalId]; 
     [item setType:Type]; 
     [item setMessagetext:Messagetext]; 
     [item setMessageType:MessageType]; 
     [item setMessageTime:MessageTime]; 
     [item setImage:Image]; 
     [item setFileUploadDetails:FileUploadDetails]; 
     [item setFirstOperatorName:FirstOperatorName]; 
     [item setRating:Rating]; 

     if (messagesList.count == 0) { 
      messagesList = [[NSMutableArray alloc] init]; 
      [messagesList addObject:item]; 

      NSMutableDictionary *dic = [NSMutableDictionary dictionary]; 
      [dic setValue:@"Adding new chatting" forKey:@"Adding new Chatting"]; 

      [[NSNotificationCenter defaultCenter] 
      postNotificationName:@"PassData" 
      object:nil 
      userInfo:dic]; 
     } else { 
      [messagesList addObject:item]; 

      NSMutableDictionary *dic = [NSMutableDictionary dictionary]; 
      [dic setValue:@"Adding new chatting" forKey:@"Adding new Chatting"]; 

      [[NSNotificationCenter defaultCenter] 
      postNotificationName:@"PassData" 
      object:nil 
      userInfo:dic]; 
     } 
    } 
} 

Diese Methode funktioniert gut, wenn es keine Emoji ist, da dieser Stachel ein einzelnes \ Emoji hat , NSJSONSerialization funktioniert nicht. Kann mir jemand helfen, dieses Problem zu beheben?

Answer 1

Das Problem besteht darin, dass Sie die JSON-Zeichenfolge fest codieren und Änderungen daran vornehmen. Nehmen Sie keine Änderungen an der Zeichenfolge JSON vor und konvertieren Sie sie direkt in NSData.

NSData *data = [historyString dataUsingEncoding:NSUTF8StringEncoding]; 
NSError *error; 
NSMutableArray* jsonArray = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error]; 
NSLog(@"Array - %@", jsonArray); 

Answer 2

Versuchen Sie es.

Convert String mit Emojis String mit Unicode wie unter

NSData *data = [strEmoji dataUsingEncoding:NSNonLossyASCIIStringEncoding]; 
NSString *unicodeString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 

Und wenn Sie irgendwo, dass emoji zeigen wollen, dann können Sie konvertieren zurück in Emoji.

NSData *data = [unicodeString dataUsingEncoding:NSUTF8StringEncoding]; 
NSString *emojiString = [[NSString alloc] initWithData:data encoding:NSNonLossyASCIIStringEncoding];
