I am using FBConnect API...And I am using this code while pressing button..
- (IBAction)postGradesTapped:(id)sender {
_posting = YES;
// If we're not logged in, log in first...
if (![_session isConnected]) {
self.loginDialog = nil;
_loginDialog = [[FBLoginDialog alloc] init];
[_loginDialog show];
}
// If we have a session and a name, post to the wall!
else if (_facebookName != nil) {
[self postToWall];
}
// Otherwise, we don't have a name yet, just wait for that to come through.
}
Now when I press the button...
White blank screen Comes up...:(
What can be the problem??
As per your code, on login success you are posting on your wall. So it may be getting blank screen. Try print something on console on login success.

I have been developing a game which allows for multiplayer matches. I had previous tested the multiplayer invitations and they had all worked. Sending a request from one device displayed a banner on the other and if the invite was accepted the game started.
Just before submitting the app, two nights ago, I tested this functionality again only to find that it has stopped working.
- (void)authenticateLocalUser:(UIViewController *)viewController :(id<GCHelperDelegate>)theDelegate
{
delegate = theDelegate;
self.presentingViewController = viewController;
if (!gameCenterAvailable) {
// Game Center is not available.
userAuthenticated = FALSE;
}
else{
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
/*
The authenticateWithCompletionHandler method is like all completion handler methods and runs a block
of code after completing its task. The difference with this method is that it does not release the
completion handler after calling it. Whenever your application returns to the foreground after
running in the background, Game Kit re-authenticates the user and calls the retained completion
handler. This means the authenticateWithCompletionHandler: method only needs to be called once each
time your application is launched. This is the reason the sample authenticates in the application
delegate's application:didFinishLaunchingWithOptions: method instead of in the view controller's
viewDidLoad method.
Remember this call returns immediately, before the user is authenticated. This is because it uses
Grand Central Dispatch to call the block asynchronously once authentication completes.

//ios 6
[localPlayer setAuthenticateHandler:(^(UIViewController* viewcontroller, NSError *error) {
if (viewcontroller != nil){
userAuthenticated = FALSE;
[self.presentingViewController presentViewController: viewcontroller animated: YES completion:nil];
}
else if (localPlayer.isAuthenticated){
// Enable Game Center Functionality
userAuthenticated = TRUE;
[self checkForInvite:self.presentingViewController :delegate];
if (! self.currentPlayerID || ! [self.currentPlayerID isEqualToString:localPlayer.playerID]) {
// Current playerID has changed. Create/Load a game state around the new user.
self.currentPlayerID = localPlayer.playerID;
// get friends of local player
[localPlayer loadFriendsWithCompletionHandler:^(NSArray *friends, NSError *error) {
if (friends != nil)
{
[self loadPlayerData: friends];
}
}];
}
}
else{
userAuthenticated = FALSE;
}
[scoreHandler setGameCentreAvailable:userAuthenticated];
})];
}
}
- (void)checkForInvite :(UIViewController *)viewController :(id<GCHelperDelegate>)theDelegate
{
delegate = theDelegate;
self.presentingViewController = viewController;
NSLog(#"Invite handler installed");
[GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite) {
// Insert application-specific code here to clean up any games in progress.
if (acceptedInvite){
NSLog(#"Accepted");
GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithInvite:acceptedInvite] autorelease];
mmvc.matchmakerDelegate = self;
[viewController presentViewController: mmvc animated: YES completion:nil];
} else if (playersToInvite) {
NSLog(#"Match Request");
GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease];
request.minPlayers = 2;
request.maxPlayers = 2;
request.playersToInvite = playersToInvite;
GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithMatchRequest:request] autorelease];
mmvc.matchmakerDelegate = self;
[viewController presentViewController: mmvc animated: YES completion:nil];
}
};
}
The debug window in xcode shows the following:
2013-03-27 18:06:20.112 MyApp[791:907] Authentication changed: player authenticated.
2013-03-27 18:06:21.219 MyApp[791:907] Invite handler installed

e = 2;
h = A42FD7FD;
}]
Is the "I am []..." significant in the lines above?
I have even downloaded and run the tutorial from Ray Wenderlich's site for creating a multiplayer game and tried that. That exhibits the same issues, unless it is running in the foreground on both devices. My app does not display invitation requests even if running in the foreground.
Has anyone else experienced this problem or have any ideas what is going on? authenticateLocalUser is called from applicationDidFinishLaunching
The only way I could make invites-by-name work is by going to Settings/Notifications/Game Center and making Game Center display Alerts, not Banners.
If you have GC display alerts, you get a popup box like this:
This dialog acts like a big parent. If the user hits Accept, then your [GKMatchmaker sharedMatchmaker].inviteHandler gets invoked.
If the user hits Decline, then your game never knows that he was invited to any party ever. User hitting Decline means the parent rips up the invitation and never tells his child he got invited to a game at all.
This is the only way I could get invite-by-name to work.
I was just checking for the state of FBSession
- (BOOL)hasValidSession {
return (self.session.state == FBSessionStateOpen)
}
Occasionally the state would briefly be changed to FBSessionStateOpenTokenExtended and this would return NO which would bring down my login modal. When I would click connect again it would crash the app for trying to reestablish an active facebook session. So I changed it to
- (BOOL)hasValidSession {
if (self.session.state == FBSessionStateOpen || self.session.state == FBSessionStateOpenTokenExtended) {
return YES;
}
else {
return NO;
}}
My above method works so far but it seems like a hack... What is the best ubiquitous way to check for a valid session in your app?
This is the way I check the facebook session in my app and it works for me:
-(BOOL)checkFacebookSession
{
if([FBSession activeSession].state == FBSessionStateCreatedTokenLoaded)
{
NSLog(#"Logged in to Facebook");
[self openFacebookSession];
UIAlertView *alertDialog;
alertDialog = [[UIAlertView alloc] initWithTitle:#"Facebook" message:#"You're already logged in to Facebook" delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil, nil];
[alertDialog show];
[alertDialog release];
return YES;
}
else{
NSLog(#"Not logged in to Facebook");
return NO; //Show login flow.
}
}
Hope it helps! :D
The session is active if the state is either in FBSessionStateOpen or in FBSessionStateOpenTokenExtended. You can use the method below to get the current status of the user is logged in:
- (BOOL)isActiveSession
{
return (FBSession.activeSession.state == FBSessionStateOpen
|| FBSession.activeSession.state == FBSessionStateOpenTokenExtended);
}
I have an app that I want to be able to connect to Facebook and post to the user's wall. I have the following code:
- (void)viewDidLoad {
static NSString* kApiKey = #"PRIVATE";
static NSString* kApiSecret = #"PRIVATE";
_session = [[FBSession sessionForApplication:kApiKey secret:kApiSecret delegate:self] retain];
// Load a previous session from disk if available. Note this will call session:didLogin if a valid session exists.
[_session resume];
// Set these values from your application page on http://www.facebook.com/developers
// Keep in mind that this method is not as secure as using the sessionForApplication:getSessionProxy:delegate method!
// These values are from a dummy facebook app I made called MyGrades - feel free to play around!
[super viewDidLoad];
}
- (IBAction)postGradesTapped:(id)sender {
_posting = YES;
// If we're not logged in, log in first...
if (![_session isConnected]) {
self.loginDialog = nil;
_loginDialog = [[FBLoginDialog alloc] init];
[_loginDialog show];
}
// If we have a session and a name, post to the wall!
else if (_facebookName != nil) {
[self postToWall];
}
// Otherwise, we don't have a name yet, just wait for that to come through.
}
The problem I have is that when the user clicks the button associated with the IBAction it will pop up the login dialog, but then the window disappears without ever pulling up the Publish Story to Wall dialog. How do I get it to login and then pull up the Publish Story to Wall?
I think you may need to use FBPermissionDialog to ask for "post to wall" permission first (I'm not sure what the exact string is; it might be in the examples).
Also note that "FBSession" is the old "iPhone" SDK (last updated in April); there's a newer "iOS" SDK at http://github.com/facebook/facebook-ios-sdk
I once encountered this behavior when my Security Key was wrong (in the new API you don't need it, but if you're based on old API it still requires it).
Make sure you use "App Id" and "App Secret" from the Facebook app control page. (And not "API Key")
Good luck!
i implement FBConnect for my app via UIActionSheet with 2buttons .
my buttons are "Share On Facebook" and "Log out from facebook" . so i want when user click on share on facebook button FBLoginDialog shows and user log in to facebook with his account and then show FBStreamDial appears and user share something on his wall . and never show FBLoginDialog again . it means just one time . and when user going to log out that method repeat again .
How can mange it ?
if i use this method : 2 method appear together !
-(void)actionSheet:(UIActionSheet *)menu didDismissWithButtonIndex:(NSInteger)buttonIndex {
switch (buttonIndex) {
case 0:
///SHOW LOGIN WINDOW
NSLog(#"asdasda");
FBLoginDialog* dialog = [[[FBLoginDialog alloc] initWithSession:session] autorelease];
[dialog show];
///SHOW FBStreamDialog
FBStreamDialog* dialog2 = [[[FBStreamDialog alloc] init] autorelease];
dialog2.delegate = self;
dialog2.userMessagePrompt = #"Share Ghazals on your wall";
dialog2.attachment = #"{\"name\":\"Hafez Application for iPhone\","
"\"href\":\"http://itunes.apple.com/us/app/divan-of-hafez/id340865571?mt=8?tab=iphone\","
"\"media\":[{\"type\":\"image\","
"\"src\":\"http://momeks.com/images/fb.png\","
"\"href\":\"http://developers.facebook.com/connect.php?tab=iphone/\"}],"
"\"properties\":{\"another link\":{\"text\":\"Hafez App HomePage\",\"href\":\"http://www.momeks.com/hafez\"}}}";
//replace this with a friends UID
//dialog2.targetId = #"999999";
[dialog2 show];
break;
case 2:
[session logout];
break;
}
}
The FBDialog's show method is asynchronous, meaning it returns before it completes whatever it is doing (in this case displaying a window).
You need to implement the delegate methods for responding to facebook dialog messages.
In the delegate methods you can outline the flow of your application.
Currently, your code show's the login dialog window, which returns instantly, and then proceeds on to show another dialog. You should only show the second dialog after the user has logged in, which you can determing using the FBSession delegate methods.
