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.
