connect Iphone with Facebook API

Question

I want to connect facebook API's with my IPhone. For this I have downloaded the FBConnect sdk and included the FBConnect group of FBConnect.xcodeproj in my application and then I have written the following code in FacebookAPPViewController.m

- (void)viewDidLoad{
     [super viewDidLoad];
     session = [FBSession sessionForApplication:@"a31c3e53bba4a5f2b3955d6e5e 876717" secret:@"6ecbefa3807406bd13187297e58efae9" delegate:self];
     FBLoginButton *button = [[[FBLoginButton alloc] init] autorelease];
     [self.view addSubview:button];

     FBLoginDialog* dialog = [[[FBLoginDialog alloc] init] autorelease];
     [dialog show];
}

but it is showing error that session undeclared . That is right also because I have not initialized it but if I declare it with class `FBSession then also It displays some error and if I exclude this line then the button to connect to facebook does not appear.

Can some one help me?

Thanks in advance

After setting up the session, you should pass it to the login dialog:

FBSession *session = [FBSession 
             sessionForApplication:@"a31c3e53bba4a5f2b3955d6e5e 876717"
             secret:@"6ecbefa3807406bd13187297e58efae9" delegate:self];

FBLoginDialog* dialog = [[[FBLoginDialog alloc] initWithSession:session] autorelease];

[dialog show];

In your example, you're opening the login dialog right away, so there's no need to add a login button to your view.

PS. I hope you didn't use your real secret key in your code sample...
