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:

How to use nsxmlparser in Iphone SDk?

-
Image
NSXMLParser is a forward only reader or an event driven parser. What it means is, an event is raised whenever the parser comes across a start of an element, value, CDATA and so on. The delegate of NSXMLParser can then implement these events to capture XML data. Some of the events are raised multiple times like the start of an element, value of an element and so on. Since NSXMLParser is known as an event driven parser, we can only read data at the present node and cannot go back. The iPhone only supports  NSXMLParser  and not  NSXMLDocument , which loads the whole XML tree in memory. Books Application To understand how to use an instance of NSXMLParser, let’s create a simple navigation based application where we will list the title of the book in the table view and upon selecting a title, display the detail information in a detail view. Click  here  to see the sample XML file, used in this application. Create a new application in XCode by selecting Navig...

About Xcode 4 features

Xcode 4 is the latest iteration of Apple’s integrated development environment (IDE), a complete tool set for building Mac OS X and iOS applications. The Xcode IDE includes a powerful source editor, a sophisticated graphical UI editor , and many other features fromhighly customization builds to support for source code repository management. Xcode can help you identify mistakes in both syntax and logic, and will even suggest fixes. Xcode 4 features a single window, called the  work space window , that holds most of the data you need. A second window, called the  Organizer window , is used for organizing your projects and reading documentation. For iOS projects, the Organizer window is also used to manage  devices. Xcode 4 has many features to make your job easier.          Xcode 4 has a single-window interface for all major workflows (you can have multiple workspace windows and multiple tabs per window)....

Blocks in iPhone?

-
As a programmer, you’re used to data types like   String , which is a variable type for text. We also are aware of things like   int ,   float , and   double , which are variable types to store numeric values. Finally, we know about things like   NSObject , which is a foundation level class that allows us to bundle various collections of both data types and methods (a.k.a. functions). Blocks bring something significantly different to the table, providing a data type for executable code storage. If that doesn’t make sense to you, don’t worry: blocks can be tough. Their purpose and function becomes much more clear upon seeing examples of their use. One of the most popular types of patterns in which blocks are used is for providing “completion blocks” to objects who perform some kind of asynchronous operation. The following is an example of a method signature provided in my UIView that takes advantage of accepting a completion block from a user: + (void)animat...
