    if (self = [super initWithCoder:aDecoder]) {
        _facebook = [[Facebook alloc] initWithAppId:@"129649123867187" andDelegate:self];
    }
    return self;
}

- (void)viewDidLoad

    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.facebookLikeView.href = [NSURL URLWithString:@"http://sis.uol.edu.pk/sis/MainForms/login.aspx"];
    self.facebookLikeView.layout = @"button_count";
    self.facebookLikeView.showFaces = NO;

    [alert show];
}

Your code seems to be OK, and you're using code of FacebookLikeView , when I tried to implement the same in my application it won't show up the login because I forgot to bind FacebookLikeView with IB. Another problem that also happened to me was, You may need to cut _facebook = [[Facebook alloc] initWithAppId:@"129649123867187" andDelegate:self]; line from init method and put it into viewDidLoad like below, because it won't called up in my case!

if(!_facebook)
{
    _facebook = [[Facebook alloc] initWithAppId:@"129649123867187" andDelegate:self];
}

I believe that you don't forget to set delegate for FBConnect , FacebookLikeViewDelegate and FBSessionDelegate

If you still can't solve out the problem, then it may be with your Facebook App ID do try to use the default app id given there in source code, it should work!
