未配置帐户时登录不起作用

Question

我正在使用我的应用程序中的Facebook SDK登录控件，只要用户在iOS的设置部分配置了他的Facebook帐户，它的工作正常。

问题是没有配置帐户报告无法登录的用户。

为了测试问题，我删除了我的帐户，确实 - 尝试登录时，我看到该应用程序正在打开Facebook应用程序/浏览器并立即将其关闭并返回登录屏幕。

是否有针对登录控件的特殊配置或实现登录的替代方法，以便它支持所有用户？

我的代码：

     FBLoginView *loginView = [[FBLoginView alloc] init];
    loginView.delegate=self;
    loginView.readPermissions = @[@"basic_info", @"email"];
    loginView.defaultAudience=FBSessionDefaultAudienceEveryone;

    loginView.frame = CGRectOffset(loginView.frame, (self.view.center.x - (loginView.frame.size.width / 2)), 270);
    [self.view addSubview:loginView];

Answer 1

添加以下代码到appdelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
     [FBLoginView class];
     return YES;
}
- (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.
    [[FBSession activeSession] handleDidBecomeActive];
}
- (void)applicationWillTerminate:(UIApplication *)application
{
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    [[FBSession activeSession] close];
}
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {
    // Call FBAppCall's handleOpenURL:sourceApplication to handle Facebook app responses
    BOOL wasHandled = [FBAppCall handleOpenURL:url sourceApplication:sourceApplication];
    // You can add your app-specific url handling code here if needed
    return wasHandled;
}
