Printing '%' in NSString formatting

Question

I need some response like 100 % but unable to print % after the number, as it comes with warning incomplete Identifier. enter image description here

I have tried searching solutions, used \%, '%' but no help.

I have found that `%%`, while the "right" way to do this, does not always work in all circumstances, and so I just make `'%'` a parameter and format with %c. — Hot Licks, Mar 04 '13 at 16:25
@HotLicks I'm curious - do you have an example where it doesn't work as expected? — rmaddy, Mar 04 '13 at 18:05
@maddy - Not at hand. And I was dealing with a lot of "mixed mode" stuff, some `stringWithFormat`, some `printf`, NSLog and other debug macros, et al, so it got pretty hairy trying to keep the exceptions straight. — Hot Licks, Mar 04 '13 at 19:25

Escape the special % character using another % character:

@"%2.0f%%"

The format specifier for a literal % is %%.
