이번 주 요일을 얻는 방법?

Question

이번 주 요일 배열을 얻으려면 어떻게해야합니까?
예 : 오늘은 saturday - 28 july입니다.
배열에 '28 Saturday '가 필요합니다. 27 Friday, 26 Thursday, 25 Wednesday ... 22 Sunday?

[코드] NSCalendar * myCalendar = [[NSCalendar 할당] initWithCalendarIdentifier : NSGregorianCalendar];

NSDateComponents *currentComps = [myCalendar components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSWeekOfYearCalendarUnit | NSWeekdayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit) fromDate:weekDate]; 
int ff = currentComps.weekOfYear; 
NSLog(@"1 %d", ff); 

[currentComps setWeekday:1]; // 1: sunday 
NSDate *firstDayOfTheWeek = [myCalendar dateFromComponents:currentComps]; 
[currentComps setWeekday:7]; // 7: saturday 
NSDate *lastDayOfTheWeek = [myCalendar dateFromComponents:currentComps]; 

NSLog(@"first - %@ \nlast - %@", firstDayOfTheWeek, lastDayOfTheWeek); [code] 

나는 이런 짓을하지만, 나는 'firstDayOfWeek'이 - 2012-07-29와 'lastDayOfWeek이'- 2012-08-04 여기

은 당신이 찾고있는 것입니다 - 당신은 그냥 필요 그에 따라 결과의 형식을 지정하십시오 :

NSDate *weekDate = [NSDate date]; 
NSCalendar *myCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; 

NSDateComponents *currentComps = [myCalendar components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSWeekOfYearCalendarUnit | NSWeekdayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit) fromDate:weekDate]; 
int ff = currentComps.weekOfYear; 
NSLog(@"1 %d", ff); 

[currentComps setWeekday:1]; // 1: sunday 
NSDate *firstDayOfTheWeek = [myCalendar dateFromComponents:currentComps]; 
[currentComps setWeekday:7]; // 7: saturday 
NSDate *lastDayOfTheWeek = [myCalendar dateFromComponents:currentComps]; 

NSDateFormatter *myDateFormatter = [[NSDateFormatter alloc] init]; 
myDateFormatter.dateFormat = @"dd EEEE"; 
NSString *firstStr = [myDateFormatter stringFromDate:firstDayOfTheWeek]; 
NSString *secondStr = [myDateFormatter stringFromDate:lastDayOfTheWeek]; 

NSLog(@"first - %@ \nlast - %@", firstStr, secondStr);
