Include a '%' in an NSString?

Question

How can I include a percent symbol (%) in my NSString?

[NSString stringWithFormat:@"Downloading (%1.0%)",  percentage]

The above code does not include the last percent in the string.

Answer 1

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.

Answer 2

Use %% to escape the percent sign.

Answer 3

[NSString stringWithFormat:@"Downloading (%g%%)",  percentage];
