我應該如何使用多個參數進行本地化？

Question

比方說，我有以下字符串：

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

我意識到我忘了本地化這個字符串，所以我代替它：

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

現在在做翻譯的時候，我發現語言X需要相反的參數;更接近於：

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

有什麼解決的事實，現在我需要格式化字符串的第二個參數是time，第三是colleagueName請最好的方法是什麼？

由於通常情況下，我的同事幾乎就按照我的要求就在這裏找到了解決辦法！顯然Objective-C具有位置參數

這些位置是1索引的，所以%1$@引用第一個參數。

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

此打印：

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

你可以嘗試這樣的：

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]; 
    }
