Answer 1

// minDate and maxDate represent your date range
NSCalendar *gregorianCalendar = [[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar];
NSDateComponents *days = [[NSDateComponents alloc] init];
NSInteger dayCount = 0;
while ( TRUE ) {
    [days setDay: ++dayCount];
    NSDate *date = [gregorianCalendar dateByAddingComponents: days toDate: minDate options: 0];
    if ( [date compare: maxDate] == NSOrderedDescending )
        break;
    // Do something with date like add it to an array, etc.
}
[days release];
[gregorianCalendar release];
