Ios 如何使用多个参数进行本地化？

假设我有以下字符串：

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

我意识到我忘了定位那个字符串，所以我替换了它：

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

---

现在，当进行翻译时，我发现语言X反过来需要参数；更接近于：

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

已完成预订的

。

现在，我需要格式化字符串的第二个参数是

time

，第三个参数是

collaguename

，请问，解决这个问题的最佳方法是什么？

您可以这样尝试：

    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];
    }

您可以这样尝试：

    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];
    }

通常情况下，我的同事几乎在我提出问题时就找到了解决方案！显然，Objective-C有位置参数

位置是1索引的，因此

%1$@

引用第一个参数

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

这张照片是：

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