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

Question

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.
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"];
NSMutableDictionary* params = [[NSMutableDictionary alloc] initWithObjectsAndKeys:
shareStr,#"description",
#"sharelink", #"link",
#"ImageName", #"picture",
nil];
[self performPublishAction:^{
[FBRequestConnection startWithGraphPath:#"me/feed" parameters:params HTTPMethod:#"POST" completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if (error)
{
NSLog(#"error in post");
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Success" message:#"Post Successfully" delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alert show];
}
}];
}];
}
//}
//===set delagate in Viewcontroller.h of mySLComposerSheet
[mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
NSString *output;
switch (result) {
case SLComposeViewControllerResultCancelled:
output = #"Action Cancelled";
break;
case SLComposeViewControllerResultDone:
output = #"Post Successfully";
break;
default:
break;
} //check if everything worked properly. Give out a message on the state.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Facebook" message:output delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alert show];
}];
}
- (void) performPublishAction:(void (^)(void)) action {
if ([[FBSession activeSession]isOpen]) {
/*
* if the current session has no publish permission we need to reauthorize
*/
if ([[[FBSession activeSession]permissions]indexOfObject:#"publish_actions"] == NSNotFound) {
[[FBSession activeSession] reauthorizeWithPublishPermissions:[NSArray arrayWithObject:#"publish_actions"]
defaultAudience:FBSessionDefaultAudienceOnlyMe
completionHandler:^(FBSession *session, NSError *error) {
action();
}];
}else{
action();
}
}else{
/*
* open a new session with publish permission
*/
[FBSession openActiveSessionWithPublishPermissions:[NSArray arrayWithObject:#"publish_actions"]
defaultAudience:FBSessionDefaultAudienceOnlyMe
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
if (!error && status == FBSessionStateOpen) {
action();
}else{
NSLog(#"error");
}
}];
}
}
