    Carl is right about the escaping, but it alone won’t work with the code you have given. You are missing a format specifier after the first percentage sign. Given percentage is a double, try:

    [NSString stringWithFormat:@"Downloading (%.1f %%)",  percentage];

    Note the %.1f, for formatting a double with one decimal. This gives 45.5 %. Use %.f for no decimals.
