【问题描述】：

在 ios 9.2 中，当我登录 facebook 时出现错误 Invalid_access token。 但是当我使用应用注册帐户登录时，它会成功登录 facebook。 我的图片在这里。

MYviewController.m 文件

-(void)loginButtonClicked

   FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
    login.loginBehavior = FBSDKLoginBehaviorWeb;
   [login logInWithReadPermissions:@[@"email"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) 
        if (error) 
            // Process error
         else if (result.isCancelled) 
            // Handle cancellations
        
        else 

            if ([result.grantedPermissions containsObject:@"email"]) 

                if ([FBSDKAccessToken currentAccessToken]) 
                   [[[FBSDKGraphRequest alloc] initWithGraphpath:@"me" parameters:@@"fields": @"first_name, last_name, picture.type(normal), accountsusername,email, gender, locale, timezone, about"]
                     startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) 
                         if (!error) 
                             NSLog(@"fetched user:%@", result);

                            NSString *fbAccessToken = [FBSDKAccessToken currentAccessToken].tokenString;
                            NSLog(@"fbAccessToken=>%@", fbAccessToken);

                         
                     ];
                
            
        
    ];

MYAppdelegate.m 文件。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
    [[FBSDKApplicationDelegate sharedInstance] application:application
                             didFinishLaunchingWithOptions:launchOptions];
    return YES;

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation 
    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                          openURL:url
                                                sourceApplication:sourceApplication
                                                       annotation:annotation];

- (void)applicationDidBecomeActive:(UIApplication *)application 

    [FBSDKAppEvents activateApp];

【参考方案1】：

试试这个

-(void)loginButtonClicked


  /*********  logout the current session ************/
   FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
  [login logOut];
  [FBSDKAccessToken setCurrentAccessToken:nil];
  [FBSDKProfile setCurrentProfile:nil];
/*********  logout the current session ************/

   /*********  start the new session for login ************/

  // FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
    login.loginBehavior = FBSDKLoginBehaviorWeb;
   [login logInWithReadPermissions:@[@"email"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) 
        if (error) 
            // Process error
         else if (result.isCancelled) 
            // Handle cancellations
        
        else 

            if ([result.grantedPermissions containsObject:@"email"]) 

                if ([FBSDKAccessToken currentAccessToken]) 
                   [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@@"fields": @"first_name, last_name, picture.type(normal), accountsusername,email, gender, locale, timezone, about"]
                     startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) 
                         if (!error) 
                             NSLog(@"fetched user:%@", result);

                            NSString *fbAccessToken = [FBSDKAccessToken currentAccessToken].tokenString;
                            NSLog(@"fbAccessToken=>%@", fbAccessToken);

                         
                     ];
                
            
        
    ];

【参考方案2】：

转到developers.facebook.com ->在该设置中添加联系电子邮件和单点登录是

然后点击App review ->您想让这个应用程序及其所有实时功能向公众开放吗？ 这应该是。
