Need a Facebook App ID before you create a new project with the SDK.


You will need a Facebook App ID before you create a new project with the SDK.

1. Create a new app on the Facebook App Dashboard, enter your app's basic information.




Once created, note the app ID shown at the top of the dashboard page. 




Alternatively, you can of course use the ID of an existing app.
Now, you need to set the Bundle Identifier and configure your Facebook application to support login from an iOS application.
(Note: this is a new step in the Facebook SDK for iOS v3.1. Previous versions of the SDK did not require this step.)
Click on the checkmark next to “Native iOS App” and supply your Bundle Identifier in the “Bundle ID” field. In addition, make sure the Facebook Login radio button is set to “Enabled”.


You can find or set your Bundle Identifier in Xcode in the Project tab.


3. Configure a new Xcode Project

Create a new Xcode project, add the Facebook SDK for iOS, its dependencies, and the Facebook App ID to its settings

In Xcode, create a new project, and select 'Single View Application' as shown below.






Provide a name and identifier as required:



Adding SDK, framework dependencies

Add the Facebook SDK for iOS Framework by dragging the FacebookSDK.framework folder from the SDK installation folder into the Frameworks section of your Project Navigator.




Choose 'Create groups for any added folders' and deselect 'Copy items into destination group's folder (if needed)' to keep the reference to the SDK installation folder, rather than creating a copy.



Add the Facebook SDK for iOS resource bundle by dragging the FacebookSDKResources.bundle file from theFacebookSDK.framework/Resources folder into the Frameworks section of your Project Navigator.








As you did when copying the Framework, choose 'Create groups for any added folders' and deselect 'Copy items into destination group's folder (if needed)'

You can also add the FBUserSettingsViewResources bundle in the same way if you expect to use that controller in your app.

The SDK relies on three other frameworks (AdSupport, Accounts and Social) to use the Facebook features built into iOS6. To add these, go to the 'Linked Frameworks and Libraries' section of the target's Summary pane, and click the 'plus' button to add them:



Note: You should use the 'Optional' flag for iOS6-specific frameworks if you would like your app to also build for older versions of the operating systems.




Once done, your Project Navigator should look something like this:


 

Adding SQLite

Next you need to add the ''-lsqlite3.0'' SQL library to the list of build dependencies in the Build Settings pane:





 


 

 

 

Adding your Facebook App ID

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:





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 withfb:
