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.

Answer 1

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);

Answer 2

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];
