Answer 1

I hope this will give you basic idea how you have to proceed: For other scenarios you can work out

- (NSDate *)firstDayOfWeekFromDate:(NSDate *)date {
      NSCalendar* calendar = [NSCalendar currentCalendar];
      NSDateComponents* comps = [calendar components:NSYearForWeekOfYearCalendarUnit |NSYearCalendarUnit|NSMonthCalendarUnit|NSWeekCalendarUnit|NSWeekdayCalendarUnit fromDate:date];

     [comps setWeekday:2]; // 2: monday
     return [calendar dateFromComponents:comps];
  }
