推荐答案

你有没有看过 FormatterKit?它工作得很好，我很确定这正是您正在寻找的.

Have you taken a look at TTTOrdinalNumberFormatter which is in FormatterKit? It works great, and I'm pretty sure it's exactly what you're looking for.

这是一个从套件中提取的示例:

Here's an example taken from the kit:

TTTOrdinalNumberFormatter *ordinalNumberFormatter = [[TTTOrdinalNumberFormatter alloc] init];
[ordinalNumberFormatter setLocale:[NSLocale currentLocale]];
[ordinalNumberFormatter setGrammaticalGender:TTTOrdinalNumberFormatterMaleGender];
NSNumber *number = [NSNumber numberWithInteger:2];
NSLog(@"%@", [NSString stringWithFormat:NSLocalizedString(@"You came in %@ place!", nil), [ordinalNumberFormatter stringFromNumber:number]]);

假设您为You come in %@ place!"提供了本地化字符串，输出将是:

Assuming you've provided localized strings for "You came in %@ place!", the output would be:

* English: "You came in 2nd place!"
* French: "Vous êtes venu à la 2eme place!"
* Spanish: "Usted llegó en 2.o lugar!"
