NSDateComponents serves an important role in Foundation’s date and time APIs. By itself, it’s nothing impressive—just a container for information about a date (its month, year, day of month, week of year, or whether that month is a leap month).

NSDateComponents can be initialized and manipulated manually, but most often, they’re extracted from a specified date, using NSCalendar -components:fromDate::

An NSDateComponents object is not required to define all the component fields. When a new instance of NSDateComponents is created the date components are set to NSUndefinedDateComponent.

Sample :

 NSCalendar *calendar = [NSCalendar currentCalendar];
 NSDate *date = [NSDate date];

 NSDateComponents *components = [[NSDateComponents alloc] init];
 [components setWeekOfYear:1];
 [components setHour:12];
 NSLog(@"1 week and twelve hours from now: %@", [calendar dateByAddingComponents:components toDate:date options:0]);
