Question

hi i use the newest facebook api with SSO and do implement like following in my viewController (not in the appDelegate like in the example if that makes any difference):
in my .h file

Facebook *facebook;
@property (nonatomic,retain) Facebook *facebook;

in my .m file i do the following in my viewDidLoad

self.facebook = [[Facebook alloc] initWithAppId:@"myappID"];

in another method I do

if (![facebook isSessionValid]) {


NSArray *permissions =  [[NSArray arrayWithObjects:@"publish_stream",nil] retain];
[facebook authorize:permissions delegate:self];
}

but it seems that isSessionValid is alway NO
and I don’t know why!
does anybody have any idea why ?
oh and also expirationDate and accessTokken are nil

Answer 1

alright here is the answer to my problem.
as I said in the comment also the application:handleOpenURL: never got called!
cause I had this method in my ViewController and apparently it has to be in the appDelegate!

so in my Navigationbar based application I did the following in my appDelegate:

in the .h file:

ViewController *viewController;
@property (nonatomic, retain) IBOutlet ViewController *viewController;

in the .m file:

@synthesize viewController;

viewController = [[ViewController alloc]init];
[self.navigationController pushViewController:viewController animated:NO];

and then implemented the method like that:

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {

return [viewController.facebook handleOpenURL:url]; 
}

and of course in my ViewController I did everything @Tyler mentioned (thank you for that)
and everything works like a charm.
hope this helps everyone with the same problem.
