Answer 1

versuchen diesen Code

NSMutableArray *weekdays = [[NSMutableArray alloc] init]; 
NSDate *today = [NSDate date]; 
NSDateComponents *comp = [[NSCalendar currentCalendar] components:NSWeekdayCalendarUnit fromDate:today]; 
for (int i=1; i <= 7 ;i++) 
{ 

    [weekdays addObject:[today dateByAddingTimeInterval:((i-[comp weekday])*24*60*60)]]; 
} 
NSLog(@"%@",weekdays); 
NSLog(@"Monday :%@ StaturDay:%@",[weekdays objectAtIndex:1],[weekdays objectAtIndex:6]);

Ich benutzte folgenden Code. Versuchen Sie, diese

NSMutableArray *daysArray; 
     NSString *weekdayStr; 
     NSMutableArray *weekdayArray; 

weekdayArray = [[NSMutableArray alloc]init]; 
    daysArray = [[NSMutableArray alloc]init ]; 
    NSDate *currentDate = [NSDate date]; 
    NSCalendar *gregorian = [[[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar] autorelease]; 

     NSDateFormatter *inputFormatter = [[NSDateFormatter alloc] init]; 
     [inputFormatter setDateFormat:@"yyyy-MM-dd"]; 

    NSDateComponents *weekdayComponents = [gregorian components:(NSDayCalendarUnit | NSYearCalendarUnit | NSMonthCalendarUnit | NSWeekCalendarUnit | NSWeekdayCalendarUnit) fromDate:currentDate]; 

    int month ; 
    int year ; 
    //int weekDay ; 
    int day ; 

    unsigned unitFlags = NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit |NSHourCalendarUnit | NSMinuteCalendarUnit; 
    for (int i = 0; i < 7; i++) { 
     day = [weekdayComponents day]-i; 
     month = [weekdayComponents month]; 
     year = [weekdayComponents year]; 
    // weekDay = [weekdayComponents weekday]-i; 

     NSDateComponents *compsTime = [gregorian components:unitFlags fromDate:[NSDate date]]; 
     [compsTime setDay:day]; 
     [compsTime setMonth:month]; 
     [compsTime setYear:year]; 

     NSString *tempString = [inputFormatter stringFromDate:[gregorian dateFromComponents:compsTime]]; 
     NSArray *separateString=[tempString componentsSeparatedByString:@" "]; 
     NSString *date=[separateString objectAtIndex:0]; 

     [daysArray addObject:date]; 

     NSDateComponents *weekdayComponents1 = [gregorian components:(NSDayCalendarUnit | NSYearCalendarUnit | NSMonthCalendarUnit | NSWeekCalendarUnit | NSWeekdayCalendarUnit) fromDate:[gregorian dateFromComponents:compsTime]]; 
     int weekDay1 = [weekdayComponents1 weekday]; 

     switch (weekDay1) { 
      case 1: 
       weekdayStr = @"(Sunday)"; 
       break; 
      case 2: 
       weekdayStr = @"(Monday)"; 
       break; 
      case 3: 
       weekdayStr = @"(Tuesday)"; 
       break; 
      case 4: 
       weekdayStr = @"(Wednesday)"; 
       break; 

      case 5: 
       weekdayStr = @"(Thursday)"; 
       break; 

      case 6: 
       weekdayStr = @"(Friday)"; 
       break; 

      case 7: 
       weekdayStr = @"(Saturday)"; 
       break; 

      default: 
       break; 
     } 
     NSLog(@"weekDay %@ date: %@",weekdayStr,tempString); 
     [weekdayArray addObject:[NSString stringWithFormat:@"%d",weekDay1]]; 
    } 
    NSLog(@"days array: %@", weekdayArray)
