ios - FBSDK findByGraphPath (me) 不返回电子邮件，即使有权限和显式字段

Question

我尝试从已登录的 Facebook 用户至少获取 ID、用户名和电子邮件。我首先使用权限类型登录:电子邮件。如果成功，尝试获取 FBSDKGraphRequest，它会返回除电子邮件之外的所有可能值。

我也尝试过添加 public_profile 之类的权限，但无论如何我都尝试过，但我没有收到电子邮件。我查看了开发人员仪表板，默认情况下似乎已批准电子邮件。

FBSDKLoginManager *loginManager = [[FBSDKLoginManager alloc] init];
[loginManager logInWithReadPermissions:@[@"email"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
    if (error) {
        NSLog(@"Error: %@", error);
        return;
    } else if (result.isCancelled) {
        return;
    }

    FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"id, name, gender, first_name, last_name, locale, email"}];

    [request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
        if (error) {
            NSLog(@"Error: %@", error);
            return;
        }

        NSLog(@"Fetched user: %@", result);
    }];
}];

你的代码应该是这样的

-(void)loginWithFacebookButtonTouchUpInside
{
    if(![FBSDKAccessToken currentAccessToken])
    {
        FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
        [login logInWithReadPermissions:@[@"email",@"public_profile"] fromViewController:nil handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
            if (error) {
                // Process error
            }
            else if (result.isCancelled)
            {
                // Handle cancellations
            }
            else
            {
                // If you ask for multiple permissions at once, you
                // should check if specific permissions missing
                [self userLoggedIn];
            }

        }];
    }else{
       //error "Authentication is not done"
    }
}

- (void)userLoggedIn
{
    [FBSDKProfile enableUpdatesOnAccessTokenChange:NO];
    [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"name, email,first_name,last_name"}]
     startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id userInfo, NSError *error) {
         if (!error) {
             {

             }
         }
     }];
}
