//Add these four delegate in .h file
<FBSessionDelegate,FBDialogDelegate,FBLoginDialogDelegate,FBRequestDelegate>

like:
@interface FacebookViewController : UIViewController <FBSessionDelegate,FBDialogDelegate,FBLoginDialogDelegate,FBRequestDelegate>{

//Now declare variables in .h file
Facebook *facebook;
NSArray *permissionsArray;

Now come to .m file and add this on the top after @implementaton
static NSString* kAppId = @"227448770601908";

//Now copy and paste from facebook start to facebook end

///facebook start
#pragma mark -
#pragma mark Facebook delegate methods

-(void)request:(FBRequest *)request didReceiveResponse:(NSURLResponse *)response{
NSLog(@"Response : %@", [[response URL] absoluteString]);
}

-(void)request:(FBRequest *)request didLoad:(id) result {
NSLog(@"result:%@",result);
NSLog(@"result:%@",[result objectForKey:@"name"]);
}

- (void)request:(FBRequest *)request didFailWithError:(NSError *) error {
NSLog(@"result:%@",[error description]);
}

-(void)fbDidLogin {
NSString *publishString = [NSString stringWithFormat:@"Blogs"];
SBJSON *jsonWriter = [[SBJSON new] autorelease];
NSDictionary* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys:@"Photo Rating",@"text",@"http://iphone-app-dev-beginners.blogspot.com/",@"href", nil], nil];
NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks];

NSDictionary* imageShare = [NSDictionary dictionaryWithObjectsAndKeys:
@"image", @"type",
@"http://iphone-app-dev-beginners.blogspot.com/", @"src",
@"http://iphone-app-dev-beginners.blogspot.com/", @"href",
nil];
NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys:

@"http://iphone-app-dev-beginners.blogspot.com/", @"href",
@"string",@"description",
[NSArray arrayWithObjects:imageShare, nil ], @"media",
nil];
NSString *attachmentStr = [jsonWriter stringWithObject:attachment];
//    NSLog(attachmentStr);
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
  kAppId, @"api_key",
  @"Share on Facebook"@"user_message_prompt",
  actionLinksStr, @"action_links",
