Answer 1

NSCalendar *gregorian = [[NSCalendar alloc]initWithCalendarIdentifier:NSGregorianCalendar];
NSDate *date = [NSDate date];
NSDateComponents *weekdayComponents = [gregorian components:NSWeekdayCalendarUnit fromDate:date];
NSInteger todayWeekday = [weekdayComponents weekday];

enum Weeks {
    SUNDAY = 1,
    MONDAY,
    TUESDAY,
    WEDNESDAY,
    THURSDAY,
    FRIDAY,
    SATURDAY
};

NSInteger moveDays=SATURDAY-todayWeekday;
if (moveDays<=0) {
    moveDays+=7;
}

NSDateComponents *components = [NSDateComponents new];
components.day=moveDays;

NSCalendar *calendar=[[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar];
NSDate* newDate = [calendar dateByAddingComponents:components toDate:date options:0];

NSLog(@"%@",newDate);
