没有得到Facebook图形API响应

Question

Facebook已经给了我“user_likes”，“user_bithday”等的许可，但我仍然没有收到它的数据，结果总是得到空白字典。请帮我解决它。

-(void)loginButtonClicked { 
     FBSDKLoginManager* lm = [[FBSDKLoginManager alloc] init]; 
     lm.loginBehavior = FBSDKLoginBehaviorSystemAccount; 
     [lm logInWithReadPermissions:@[@"public_profile", @"email", @"user_birthday", @"user_likes"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) { 
     if (!error && !result.isCancelled) 
     { 
      [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me/likes" parameters:@{@"fields":@"id, name, first_name, last_name, picture.type(large), email, birthday, likes"}] 
      startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) { 
       if (!error) { 
        NSLog(@"fetched detail: %@",result); 
       } 
      }]; 
     } 

    }]; 
}

首先，您需要检查在FB图形浏览器是乌拉圭回合得到响应

https://developers.facebook.com/tools/explorer/

如果你得到这个响应，你会得到响应代码也。

玩转编码。

试试这个，它应该返回ü一些值。
