IOS does not call Facebook authentication callback

I am making a facebook application using the latest version of Xcode4.2 and the Facebook SDK. I copied the hackbook to my application and replaced the method name. Then it worked! [Enter image description here] [1]

But when I click the "OK" button, there is no answer. I checked the details. Somehow, iOS does not call OpenURL in appdelegate.m.

Why doesn’t iOS call the method? Here is the code.

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url { return [self.facebook handleOpenURL:url]; } - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation { return [self.facebook handleOpenURL:url]; }

Please let me know what happened.

Thanks in advance.

Have you set your Facebook ID in your application properties list file? If you have not done so, the Facebook application does not call a callback for your application.

Read the instructions here in the "Modify the application properties list file" section: https://developers.facebook.com/docs/mobile/ios/build/

Basically, you need to create a new line in your application layer with URL type names with one element, URL schemes containing a single value, fbYOUR_APP_ID (literal characters fb followed by your application identifier).

I also had this error after it already worked, and it turned out that several xcode restarts completed its fix.
