ios - iOS での日付と時刻の書式設定

Question

私はNSDateFormatterを知っていますが、「昨日の12:35」のようにしたいのですが、2つの日付文字列を連結しているだけですか?

[dateFormatter setTimeStyle:NSDateFormatterNoStyle];
[dateFormatter setDateStyle:NSDateFormatterShortStyle];
[dateFormatter setLocale: [NSLocale autoupdatingCurrentLocale]];

[dateFormatter setDoesRelativeDateFormatting:YES];

[dateFormatterTime setLocale:[NSLocale systemLocale]];
[dateFormatterTime setDateFormat:@"HH:mm"];

NSString *dateString = [NSString stringWithFormat:@"%@ %@", [dateFormatter stringFromDate:dateParsed], [dateFormatterTime stringFromDate:dateParsed ] ];

何か案は？

これは、ロケールを尊重することで私ができる最善のことです。

NSDateFormatter *dateFormatter = NSDateFormatter.new;
dateFormatter.doesRelativeDateFormatting = YES;
dateFormatter.dateStyle = NSDateFormatterShortStyle;
dateFormatter.timeStyle = NSDateFormatterShortStyle;

NSDate *today = NSDate.new;
// "Today, 11:40 AM"
NSLog(@"%@", [dateFormatter stringFromDate:today]);

NSDate *tomorrow = [NSDate dateWithTimeIntervalSinceNow:60*60*24];
// "Tomorrow, 11:40 AM"
NSLog(@"%@", [dateFormatter stringFromDate:tomorrow]);

NSDate *yesterday = [NSDate dateWithTimeIntervalSinceNow:-(60*60*24)];
// "Yesterday, 11:40 AM"
NSLog(@"%@", [dateFormatter stringFromDate:yesterday]);

NSDate *dayAfter = [NSDate dateWithTimeIntervalSinceNow:(60*60*24)*2];
// "2/14/13, 11:40 AM"
NSLog(@"%@", [dateFormatter stringFromDate:dayAfter]);
