“%” symbol in an NSLocalizedString

Question

I have the following line of code:

NSLog([NSString stringWithFormat:NSLocalizedString(@"KEY", nil),80.1]);

The 80.1 is a float that is being inserted into the localized string. This works fine. However I want a % symbol in the localized string. I have tried using %%, but it does not output the % symbol - instead it outputs a space, the numbers 5302 and also removes part of the string that precedes the %% characters.

How can I add a % symbol to a string returned by NSLocalizedString?

Answer 1

I think the problem is not with the NSLocalizedString, but with NSLog's interpretation of % symbol. If you pass a format string to NSLog, and put the string that you would like to show as an object parameter, the percentage sign % should survive:

NSLog(@"%@", [NSString stringWithFormat:NSLocalizedString(@"KEY", nil),80.1]);

Answer 2

Alternatively: The first argument for NSLog is a format string. You've got a format string, so you should pass it to NSLog:

NSLog (NSLocalizedString (@"KEY", nil), 80.1);
