Facebook Session Closed - ios

Question

I'm implementing the Facebook Login in my iOS app. I think it is well implemented, however I have a problem. I run the login at the settings of the application. When I leave the app and then when I come back, if I want to use a Facebook action (i.e. share photos) I'm not able to do that because the session is closed. When I go to the settings menu where I've the login button, the session reopen without perform the login again (just direct me to the view where is the login button and the session is opened again).
So, I need the active session without the user having (always) to go to the settings menu. Any suggestions?
Thanks

I faced same problem :
had to make
#property (strong, nonatomic) FBSession *session;
in AppDelegate
in
(void)applicationDidBecomeActive:(UIApplication *)application {
[FBAppEvents activateApp];
[FBAppCall handleDidBecomeActiveWithSession:self.session]; }
in
(void)applicationWillTerminate:(UIApplication *)application { [self.session close]; }
in
(BOOL)application:(UIApplication *)application
openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
return [FBAppCall handleOpenURL:url
sourceApplication:sourceApplication
withSession:self.session]; }
in your settings class
if (appDelegate.session.isOpen)
{
[FBSession setActiveSession:appDelegate.session];
[[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection,
NSDictionary *user, NSError *error)
{
[self registerationWithFBRequestConnection:connection andFBGraphUser:user andNSError:error];
}];
}
else
{
[appDelegate.session closeAndClearTokenInformation];
NSArray *permissions = [NSArray arrayWithObjects:#"email", nil];
appDelegate.session = [[FBSession alloc] initWithPermissions:permissions];
[FBSession setActiveSession:appDelegate.session];
[appDelegate.session openWithBehavior:(FBSessionLoginBehaviorWithFallbackToWebView)
completionHandler:^(FBSession *session, FBSessionState status, NSError
*error)
{
[self sessionStateChangedWithFBSession:session andFBSessionState:status andNSError:error];
}];
}
(void)sessionStateChangedWithFBSession:(FBSession*)session andFBSessionState:(FBSessionState)status andNSError:(NSError*) error {
switch (status)
{
case FBSessionStateOpen:
{ [[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection,
NSDictionary *user, NSError *error)
{
[self registerationWithFBRequestConnection:connection andFBGraphUser:user andNSError:error];
}]; }
break;
case FBSessionStateClosed:
break;
case FBSessionStateClosedLoginFailed:
break;
default:
break;
} }
in your in registerationWithFBRequestConnection: methods you should handle it.. in Settings get all information about user.
