Integrating Facebook SDK for older versions of Xcode to Support both iOS 5 and iOS 6

I am still using XCode 4.3.2 and iOS 5.1 base SDK. What I want to achieve is to integrate Facebook API for iOS 5.0+ devices. Just basic features such as posting on behalf and getting basic user information.

I am assuming that which ever Facebook SDK works on iOS 5, will work on iOS 6, but I am not sure about that.

  • Using Non-ARC Code in an ARC-Enabled Project - Adding Facebook
  • iOS Development: How can I get a Facebook wall post to show in the friend's news feed?
  • How do I customize a UIActivityViewController to show a URL link when posting to facebook and twitter?
  • Facebook. How to get list of all users of my app?
  • How to use Facebook iOS SDK on iOS 10
  • iOS: Facebook Login access token error: Falling back to loading access token from NSUserDefaults because of simulator bug
  • As a rookie on Facebook Integration, can anybody shed some light on this issue. ( Since I am working on the project, upgrading the XCode and the iOS SDK is not an option)

    • Which iOS SDK should I be looking into?
    • Can I support both iOS 5 and
      6, with base SDK 5.1 and XCode 4.3?
    • Is there an API supporting both iOS versions?
    • Any musts for Facebook Integration?

    First of all you read this article published from Facebook developers

    http://developers.facebook.com/docs/getting-started/facebook-sdk-for-ios/

    in step 1 it will also work for xcode 4.3

    you carefully read all steps one by one n implement

    In step6 you write code as follow on where Facebook Btn Pressed

     - (IBAction)facebookBtnPressed:(id)sender
    {
    
    
            // if it is available to us, we will post using the native dialog
            BOOL displayedNativeDialog = [FBNativeDialogs presentShareDialogModallyFrom:self
                                                                            initialText:[NSString stringWithFormat:@"Here U write code which u want to post on facebook"]
                                                                                  image:[UIImage imageNamed:@"1.jpg"]
                                                                                    url:[NSURL URLWithString:@""]
                                                                                handler:nil];
    
            if (!displayedNativeDialog)
            {
                NSString *shareStr = [NSString stringWithFormat:@"Here U write code which u want to post on facebook"];
