This document discusses iPhone application development using iOS programming and the Facebook API. It provides an overview of key concepts in iOS apps like view controllers and their lifecycle. It then reviews the general process for building iPhone apps with MVC. Next, it covers the Facebook iOS SDK and methods for authentication, dialogs and requests. It outlines the steps for creating a Facebook iOS app, including registering the app, installing the SDK, implementing single sign-on and requesting additional permissions. It also discusses adding Graph API calls and social channels to an app.

8. Key objects in an iOS app

10. View Controller

11. View Controller
• Important property in UIViewController
@property (retain) UIView *view;
a pointer to top-level UIView in the Controller’s View
• View Controller have a “lifecycle” from creation
to destruction
- (id)initWithNibName:(NSString *)nibName bundle:(NSBundle *)aBundle;
initializer

12. View Controller
• After the UIViewController is initialized,
viewDidLoad is called
- (void)viewDidLoad;
• Just before the view appears on screen, you
get notified
- (void)viewWillAppear:(BOOL)animated;

13. 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).

14. Segues a pointer to top-level UIView in the Controller’s View
