Include a '%' in an NSString?

+3 A:

Use %% to escape the percent sign.

Thanks! However, %% didn't work but %%% did. Go figure.

@TomH, then you still have something wrong with your code - check out @Mads answer for more details.

Answer 3

+2 A:

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.

Thanks very much -- can't believe that I was leaving out the format specifier. Looking at the code for far too long yesterday.
