Answer 1

From your code i found that the problem is in this code coz in iOS 5 Facebook is not available in SLCompose only Twitter is available so your FaceBook is handling by DEFaceBook
DEFacebookComposeViewControllerCompletionHandler completionHandler = ^(DEFacebookComposeViewControllerResult result) {
switch (result) {
case DEFacebookComposeViewControllerResultCancelled:
NSLog(#"Facebook Result: Cancelled");
break;
case DEFacebookComposeViewControllerResultDone:
ALERT_VIEW(#"Successfully posted to facebook.");
break;
}
[self dismissViewControllerAnimated:YES completion:nil];
};
DEFacebookComposeViewController *facebookViewComposer = [[DEFacebookComposeViewController alloc] init];
self.modalPresentationStyle = UIModalPresentationCurrentContext;
[facebookViewComposer setInitialText:quotesss];
facebookViewComposer.completionHandler = completionHandler;
[self presentViewController:facebookViewComposer animated:YES completion:nil];
[facebookViewComposer release];
}
So go to your appdelegate and check this method that a valid token(url which contains your application, token format is applicationURLSchema://"token") check it is coming or not in this method
If necessary keep break point and go through the FBSession class then handleOpenURL method and find where error is happening
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
// attempt to extract a token from the url
return [FBSession.activeSession handleOpenURL:url];
}
