View Controller
• Important property in UIViewController
• View Controller have a “lifecycle” from creation to destruction
@property (retain) UIView *view;
a pointer to top-level UIView in the Controller’s View
- (id)initWithNibName:(NSString *)nibName bundle:(NSBundle *)aBundle;
initializer
View Controller
• After the UIViewController is initialized, viewDidLoad is called
• Just before the view appears on screen, you get notified
- (void)viewDidLoad;
- (void)viewWillAppear:(BOOL)animated;
View Controller
• Creating a UIViewController’s UI in code (no .xib, no storyboard)
• override - (void)loadView;
• set self.view
*Do NOT implement loadView if you use a storyboard/.xib to create the UIViewController. *Do NOT set self.view anywhere else besides in loadView. *Do NOT implement loadView without setting self.view (i.e. you must set self.view in loadView).

4. Make connec5onsa. SeDng a pointerb. SeDng targets and ac5ons
5. Implemen5ng methodsa. Ini5al methodb. Ac5on methods
6. Build and run on the simulator7. Test applica5on on the device
