How to use iOS 6's social framework

social.m

/*
 *	This code uses the Social.framework & the AFNetworking library

ACAccountStore *store;
ACAccountType  *accountType;

//Create an ACAccountStore instance
store = [[ACAccountStore alloc] init];

//Get the FB Account type
accountType = [store accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

//Request access to the account
[store requestAccessToAccountsWithType:accountType
							   options:@{
									@"YOUR_FB_APP_ID",ACFacebookAppIdKey,
									@[@"FB_PERMISSIONS"],ACFacebookPermissionsKey
								}

									SLRequest *request;
									AFJSONRequestOperation *operation;
									//Get the account
									accounts = [[store accountsWithAccountType:accountType];

									//Accounts is a list of valid fb accounts
									//Ideally you should allow the user to chose if there is more than a single account
									account = [accounts objectAtIndex:0];
									
									//Lets construct a request
									request = [SLRequest requestForService:SLServiceTypeFacebook

																	   URL:[NSURL URLWithString:@"http://graph.faceboo.com/me"]
																parameters:nil
										];
									
									//We must set the account we want to use with each request
									[request setAccount:account];
									
									//At this point we can execute the SLRequest using performRequestWithHandler: method
									// or we can extract a NSURLRequest using the preparedURLRequest method and use a 3rd party framework like AFNetworking
									
									//We use the fantastic AF Networking
									operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:[request preparedURLRequest]]
