7. Step 2: Run the sample
Basic samples
• HelloFacebookSample: combines use of FBLoginView, FBProfilePictureView,
FBFriendsPickerViewController, FBPlacePickerViewController, and FBRequest for
profile access, status updates and photo uploading.
• ProfilePictureSample: demonstrates non-logged-in usage of the
FBProfilePictureView control.
• FriendPickerSample: demonstrates usage of the native multi-friend selector control
to choose amongst the logged-in users' friends.
• PlacePickerSample: demonstrates logged-in usage of the FBPlacePickerView
control.
More in-depth single feature samples
• SessionLoginSample: demonstrates detailed login flow via FBSession.
• JustRequestSample: demonstrates logged in user making a request of Facebook via
FBRequest and FBRequestConnection, including batched requests.
• BooleanOGSample: demonstrates publishing an Open Graph custom action type.
More complete and special-case samples
• Scrumptious: integrated sample app demonstrating the use of login, requests, Place
Picker, Friend Picker, Picture Upload, and Open Graph Publishing.
• SwitchUserSample: demonstrates an approach to allow switching logins between
multiple users - for example, on a shared family iPad.
11. Step 4: Start new X-code Project
Add the Facebook SDK for iOS Framework by dragging the FacebookSDK.frameworkfolder
from the SDK installation folder into the Frameworks section of your Project Navigator.
12. Step 4: Start new X-code Project
Add the Facebook SDK for iOS resource bundle by dragging
theFacebookSDKResources.bundle file from theFacebookSDK.framework/
Resources folder into the Frameworks section of your Project Navigator.
13. Step 4: Start new X-code Project
Add the ''-lsqlite3.0'' SQL library to the list of build dependencies
14. Step 4: Start new X-code Project
Finally, you need to place the Facebook app ID in two places in your application's
main.plist file. Create a key called FacebookAppID with a string value, and add
the app ID there:
250959118344050
15. Step 4: Start new X-code Project
Also, create an array key called URL types with a single array sub-item called URL
Schemes. Give this a single item with your app ID prefixed with fb:
This is used to ensure the application will receive the callback URL of the web-based OAuth flow.
16. Step 5: FACEBOOK Login & Authenticate

// To-do, show logged in view
} else {
// No, display the login page.
[self showLoginView];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.mainViewController = [[MyAppViewController alloc] initWithNibName:@"MyAppViewController_iPhone" bundle:nil];
self.navController = [[UINavigationController alloc] initWithRootViewController:self.mainViewController];
self.window.rootViewController = self.navController;
[self.window makeKeyAndVisible];
if (FBSession.activeSession.state == FBSessionStateCreatedTokenLoaded) {

2) activeSession on FBSession has been opened, or else provide an explicit FBSession
instance to the FBRequestcalls.
3) requestForMeWithSession that returns an FBRequestobject
4) The user data will be a strongly typed FBGraphUser object
5) Once you've constructed an FBRequest object, you can initiate the API call by invoking
thestartWithCompletionHandler: method.
