 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 setday:2]; // 1: sunday [currentcomps setweek: [currentcomps week] - 1]; nslog(@"currentcomps setweek:>>>>>>  %@", currentcomps); nsdate *firstdayoftheweek = [mycalendar datefromcomponents:currentcomps]; nslog(@"firstdayoftheweek>>>>>>  %@", firstdayoftheweek); nsstring *firststr = [mydateformatter stringfromdate:firstdayoftheweek]; lbl_day1.text = firststr; 

// start date, e.g. now: nsdate *now = [nsdate date]; nscalendar *cal = [nscalendar currentcalendar];  // compute beginning of current week: nsdate *date; [cal rangeofunit:nsweekcalendarunit startdate:&date interval:null fordate:now];  // go 1 week start of previous week: nsdatecomponents *comp1 = [[nsdatecomponents alloc] init]; [comp1 setweek:-1]; date = [cal datebyaddingcomponents:comp1 todate:date options:0];  // output format (adjust needs): nsdateformatter *fmt = [[nsdateformatter alloc] init]; [fmt setdateformat:@"eeee dd/mm/yyyy"];  // repeatedly add 1 day: nsdatecomponents *comp2 = [[nsdatecomponents alloc] init]; [comp2 setday:1]; (int = 1; <= 7; i++) {     nsstring *text = [fmt stringfromdate:date];     nslog(@"%@", text);     date = [cal datebyaddingcomponents:comp2 todate:date options:0];  } 

output:
