            [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];
        }
    }
}

This method works fine if there is no emoji, since this sting has a single \ emoji , NSJSONSerialization is not working. Can some one help me to fix this issue.

You need to replace that "Two Hear emoji" with blank string if you are not going to use it. OR replace it with its unicode. — Wolverine, Feb 07 '17 at 06:03

The problem is you are hardcoding the JSON string and making changes on it, don't do make any changes with your JSON string and directly convert it to NSData.

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

Try this.

Convert string with emoji to string with unicode like below

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

And if you want to show that emoji somewhere then you can convert back in to emoji.

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