Answer 1

See the documentation for NSCalendar and NSDateComponents

Answer 2

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"D"];
NSDate *date = [NSDate date];

NSLog(@"Today: %@", date);
NSLog(@"Date Formatted: %@", [dateFormatter stringFromDate:date]);

[dateFormatter release];
