I have a great solution for it. Apply this method for remove escaped characters.

-(NSString *)removeUnescapedCharacter:(NSString *)inputStr
{

NSCharacterSet *controlChars = [NSCharacterSet controlCharacterSet];

NSRange range = [inputStr rangeOfCharacterFromSet:controlChars];

  if (range.location != NSNotFound) 
  {

      NSMutableString *mutable = [NSMutableString stringWithString:inputStr];

      while (range.location != NSNotFound) 
      {

          [mutable deleteCharactersInRange:range];

          range = [mutable rangeOfCharacterFromSet:controlChars];

      }

      return mutable;

   }

  return inputStr;
}

Call this method with passing your output string like this

NSString *output = [NSString stringWithContentsOfURL:[NSURL URLWithString:@"yourUrlString"] encoding:NSUTF8StringEncoding error:nil];

output = [self removeUnescapedCharacter:output];
