Displaying percentage using NSString

How do we display percentage character in objective-c?

I am using this:

[NSString localizedStringWithFormat:@"%.2f %", percentageQs]

But for some reason, it doesn't recognize the %. thought i could esca开发者_如何学Cpe it using this \ but i was so wrong.

There was a similar question tagged C asked earlier today: How to escape the sign in C . Answer here is the same... use a double %%.

% is used as an escape character, e.g. %@, %i, etc.

So to use the % sign then you use two, i.e. %%

The code for percent sign in NSString format is %%. This is also true for NSLog() and printf() formats.
