You want to allow the users of your app to select a date and time using an intuitive and ready-made user interface.

Use the UIDatePicker class.

UIDatePicker is very similar to the UIPickerView class. The date picker is in fact a prepopulated picker view. A good example of the date picker control is in the Calendar app on the iPhone (Figure 2-14).

Figure 2-14. A date picker shown at the bottom of the screen

Let’s get started by first declaring a property of type UIDatePicker and then allocating and initializing this property and adding it to the view of our view controller:

#import <UIKit/UIKit.h>

@interface Picking_Date_and_Time_with_UIDatePickerViewController
           : UIViewController

@property (nonatomic, strong) UIDatePicker *myDatePicker;

@end
