In my application I’m using following codes to retrieve current date and day:

NSDate *today1 = [NSDate date];
    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat:@"dd/MM/yyyy :EEEE"];
    NSString *dateString11 = [dateFormat stringFromDate:today1];

    NSLog(@"date: %@", dateString11);
    //[dateFormat release];
    NSCalendar *gregorian11 = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];  
    NSDateComponents *components1 = [gregorian11 components:NSWeekdayCalendarUnit | NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit fromDate:today1];
    [components1 setDay:([components1 day]-([components1 weekday]-1))];

    NSDate *beginningOfWeek1 = [gregorian11 dateFromComponents:components1];
    NSDateFormatter *dateFormat_first = [[NSDateFormatter alloc] init];
    [dateFormat_first setDateFormat:@"dd/MM/yyyy :EEEE"];
    NSString *dateString_first = [dateFormat_first stringFromDate:beginningOfWeek1];

    NSLog(@"First_date: %@", dateString_first);

but using above code I only got the current day and Date and first day of week but I need to get last day of week.

Where I’m wrong in my code and what modification is needed to get last day/date of week?

    If you have an NSDate, you can use the current NSCalendar to retrieve that date’s NSDateComponents. Set the NSDateComponents’s weekday to 1 (the first day of the week), create a copy, and set the copy’s weekday to 7 (the last day of the week). Then use the NSCalendar to convert both the NSDateComponents back to their respective NSDate objects, after which you can use an NSDateFormatter to create your string representation.

    This link has an example about how to get a date’s weekday:

    Another approach as suggested by vikingosegundo to get both start and end days
    rangeOfUnit:startDate:interval:forDate:. It gives you the start and the interval for a certain time unit. With it it is easy to find the start of the week in the used calendar and add the range-1 to get the latest second in that week.

    NSCalendar *cal = [NSCalendar currentCalendar];
NSDate *now = [NSDate date];
NSDate *startOfTheWeek;
NSDate *endOfWeek;
NSTimeInterval interval;
[cal rangeOfUnit:NSWeekCalendarUnit 
       startDate:&startOfTheWeek 
        interval:&interval 
         forDate:now];
//startOfWeek holds now the first day of the week, according to locale (monday vs. sunday)

endOfWeek = [startOfTheWeek dateByAddingTimeInterval:interval-1];
// holds 23:59:59 of last day in week.
