Facebook SDK登录没有收到任何回调

Question

在向应用提供权限后，我没有收到来自facebook的任何回调。应用程序只是打开fb浏览器，请求权限然后卡在页面上。我的fb App已经单点登录，并且对一般公共用途有效。我还在那里提供了我的包标识符。

您可以在此处查看我的AppDelegate配置：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    if ([[GPPSignIn sharedInstance] authentication]) {
        NSLog(@"User is logged In already");

    }else{
        NSLog(@"User is not logged In already");

    }

    //return YES;

    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                    didFinishLaunchingWithOptions:launchOptions];
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
    [FBSDKAppEvents activateApp];
}

#pragma mark - Social callback Delegates
- (BOOL)application: (UIApplication *)application
            openURL: (NSURL *)url
  sourceApplication: (NSString *)sourceApplication
         annotation: (id)annotation {
    defaults = [NSUserDefaults standardUserDefaults];
    BOOL urlStatus;
    NSString *socialNetwork = [defaults objectForKey:@"socialNetwork"];
    if([socialNetwork isEqualToString:@"google"])
    {
        urlStatus = [GPPURLHandler handleURL:url
                           sourceApplication:sourceApplication
                                  annotation:annotation];
    }
    else if([socialNetwork isEqualToString:@"facebook"])
    {
        urlStatus = [[FBSDKApplicationDelegate sharedInstance] application:application
                                                                   openURL:url
                                                         sourceApplication:sourceApplication
                                                                annotation:annotation];
    }
    return urlStatus;
}

我的登录方法如下所示：

-(void) loginWithFacebook
{
    FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
    [defaults setObject:@"facebook" forKey:@"socialNetwork"];
    [login logInWithReadPermissions:@[@"email"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error)
    {
        if (error || result.isCancelled)
        {
            // Process error
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:[error localizedDescription] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];
            [alert show];

        }

        else
        {
            // If you ask for multiple permissions at once, you
            // should check if specific permissions missing
            if ([result.grantedPermissions containsObject:@"email"])
            {
                // Do work
                isValid = YES;
                [self performSegueWithIdentifier:@"LoginWithFacebook" sender:self];
            }

        }
    }];
}

以下是.plist和链接库的图像。

屏幕截图中没有URL标识符，但我添加了它。 你能告诉我我做错了什么吗？或者可能缺少什么？

检查这2个方法

- (void)applicationDidBecomeActive:(UIApplication *)application
{


    [FBAppEvents activateApp];

}

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation
{

    return [FBSession.activeSession handleOpenURL:url];

}
