Question

我们说我有以下字符串：

[NSString stringWithFormat:@"Booked for %@ at %@", colleagueName, time];

我意识到我已经忘记了将字符串本地化，所以我将其替换掉：

[NSString stringWithFormat:NSLocalizedString(@"bookings.bookedFor", "Booked for user at time"), colleagueName, time];

现在进行翻译时，我发现语言X需要反过来的参数;更贴近的事情：

<time> for booking of <colleague> is done.

现在我需要将格式化字符串的第二个参数设为time，将第三个参数设为colleagueName，这是解决这个问题的最佳方法吗？

Answer 1

通常情况下，我的同事几乎在我问到这个问题时就找到了解决方案！显然，Objective-C有位置参数

这些位置是1索引的，因此%1$@指的是第一个参数。

NSString *firstParam = @"1st";
NSString *secondParam = @"2nd";
NSLog(@"First %1$@ Second: %2$@", firstParam, secondParam);
NSLog(@"Second %2$@ First: %1$@", firstParam, secondParam);

打印：

First 1st Second: 2nd   
Second 2nd First: 1st

Answer 2

您可以尝试这样：

    NSString * language = [[NSLocale preferredLanguages] objectAtIndex:0];
    if ([language isEqualToString:@"X"]) {//X is language code like "fr","de"
      [NSString stringWithFormat:NSLocalizedString(@"bookings.bookedFor", "Booked for user at time"), time, colleagueName];
    } else {
      [NSString stringWithFormat:NSLocalizedString(@"bookings.bookedFor", "Booked for user at time"), colleagueName,time];
    }

我应该如何使用多个参数进行本地化？
