I was wondering, however, how I can access certain parts of this date. There is the - (NSArray *)weekdaySymbols but I have no idea how to work this one and the documentation is quite frugal.日历专家的任何提示都将受到欢迎。Any hints from calendar experts would be very welcome. EDIT：我想这是解决方案的一部分：I guess this is part of the solution: NSLocale *gbLocale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_GB"];NSString *gbFormatString = [NSDateFormatter dateFormatFromTemplate:@"EdMMM" options:0 locale:gbLocale];NSLog(@"gbFormatterString: %@", gbFormatString);// Output: gbFormatterString: EEE d MMM, e.g. Thu 7 Apr推荐答案 n.evermind，n.evermind,您将需要这样的： NSDate *date = [NSDate date]; NSDateFormatter *formatter = [[[NSDateFormatter alloc] init] autorelease]; [formatter setDateFormat:@"MMM dd, yyy"]; date = [formatter dateFromString:@"Apr 7, 2011"]; NSLog(@"%@", [formatter stringFromDate:date]); NSCalendar *calendar = [NSCalendar currentCalendar]; NSInteger units = NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit | NSWeekdayCalendarUnit; NSDateComponents *components = [calendar components:units fromDate:date]; NSInteger year = [components year]; NSInteger month=[components month]; // if necessary NSInteger day = [components day]; NSInteger weekday = [components weekday]; // if necessary NSDateFormatter *weekDay = [[[NSDateFormatter alloc] init] autorelease]; [weekDay setDateFormat:@"EEE"]; NSDateFormatter *calMonth = [[[NSDateFormatter alloc] init] autorelease]; [calMonth setDateFormat:@"MMMM"]; NSLog(@"%@ %i %@ %i", [weekDay stringFromDate:date], day, [calMonth stringFromDate:date], year );输出2011-04-07 12:49:23.519 test[7296:207] Apr 07, 20112011-04-07 12:49:23.521 test[7296:207] Thu 7 April 2011乔丹，乔丹 这篇关于objective-c：将日期字符串转换为星期几+星期名称的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
