Mac OS X 10.8 Mountain LionおよびiOS 6からNSDateFormatterで日本の元号表記が変わりました。ただし日本語以外で表記する場合。
元号表記というのは今年であれば"平成"。以下のようにフォーマット指定子"G"で表示できる。
NSCalendar *japanese = [[NSCalendar alloc] initWithCalendarIdentifier:NSJapaneseCalendar];
NSDateFormatter *aFormatter = [[NSDateFormatter alloc] init];
aFormatter.calendar = japanese;
aFormatter.dateFormat = @"G y/M/d";
NSLog(@"%@", [aFormatter stringFromDate:[NSDate date]]);

この元号表記がどこまで可能かというと実は「大化」から「平成」までが組み込まれている。全ての元号が連続しているとか、北朝元号がないとか色々な問題があるにはあるが、それでもひとつの考え方として連続した元号を表示できるのは大した者である。
これを日本以外のロケールで表示すると少々違う結果が得られることがある。今の元号表記は「平成」だがこれが英語表記であれば「Heisei」となる。これは当たり前。では今流行の坂本龍馬が生きた時代1865年ではどうだろうか？日本語では「慶応」である。英語では「Keiō (1865-1868)」となる。
あれあれ？元号が知りたいだけなので「Keiō」で十分なのだがご親切にも西暦で何年から何年までだったかを教えてくれている。これは便利なようで不便。元号が知りたいのに、元号＋開始年、終了年を必ず取り出してしまう。
実はこれは「明治」「大正」「昭和」「平成」には適用されない。「慶応」以前の歴史的元号だけである。誕生日などの表記でもよく使われる現代の元号にまでこれを表記するのは不便だということはアップルもよく承知しているわけである。
ではなぜそれ以前の歴史的元号には期間の表記があるのか？慶応とか言われてもいつの元号かどっちが先でどっちが後かわからないから？ではなく、日本語で表記する場合には異なる表記になるが、英語などで表記すると同じになってしまう元号が存在するからそれを区別するため。例えば「昭和」と「正和」は別の元号だが英語だと「Shōwa」とどちらも同じになってしまう。これを避けるために期間を追加したということだ。こうすると前者は「Shōwa」後者は「Shōwa (1312-1317)」で区別できる。他にも正平／承平、正暦／承暦、永承／永正などが英語で同じ表記になる（かな表記での発音に異論の余地はあるのだが、ここではアップルの使用している発音による）。
変更を確認するのは例えば以下のようなコードでロケール指定子を"ja_JP"と"en_US"で切り替えてみる。
NSCalendar *japanese = [[NSCalendar alloc] initWithCalendarIdentifier:NSJapaneseCalendar];
NSLocale *aLocale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US"];
NSDateFormatter *aFormatter = [[NSDateFormatter alloc] init];
aFormatter.calendar = japanese;
aFormatter.locale = aLocale;
aFormatter.dateFormat = @"G";
NSDate *aDate;
NSDateComponents *comps = [[NSDateComponents alloc] init];
comps.year = 1;
comps.month = 12;
comps.day = 31;
comps.era = 234;
aDate = [japanese dateFromComponents:comps];
NSLog(@"%@",[aFormatter stringFromDate:aDate]);
comps.era = 148;
aDate = [japanese dateFromComponents:comps];
NSLog(@"%@",[aFormatter stringFromDate:aDate]);

ここでもし余計な期間が必要ない場合には以下のようなコードで削除することができる。
int main(int argc, const char * argv[])
{

NSCalendar *japanese = [[NSCalendar alloc] initWithCalendarIdentifier:NSJapaneseCalendar];

comps.year = 1;

NSString *aString = [aFormatter stringFromDate:aDate];
