我使用 FBGraph 在我的应用程序中集成了 facebook。现在我需要显示用户组，包括组成员。 **更新显示完整修复。
为此，我有以下代码：
[FBSession openActiveSessionWithReadPermissions:@[@"groups"]
allowLoginUI:NO
completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
switch (state) {
case FBSessionStateOpen:
[[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
if (error) {
NSLog(@"error:%@",error);
}
else
{
}
}];
break;
case FBSessionStateClosed:
case FBSessionStateClosedLoginFailed:
[FBSession.activeSession closeAndClearTokenInformation];
break;
default:
break;
}
} ];
它总是返回FBSessionStateClosedLoginFailed。为什么会这样？
【问题讨论】：
-
您如何让用户最初通过 facebook 登录您的应用程序？因为如果您对第一次使用的用户使用 openActiveSessionWithReadPermissions，那是行不通的。

嗨，Davetw，我进行了更改以从上面的 Facebook 中获取组。现在它正确地返回了组数据。但我这里有一个问题。每当应用程序回到后台并再次重新启动时，它都会抛出一个错误，提示 code = 2500; message = "必须使用活动访问令牌来查询有关当前用户的信息。";类型 = OAuthException;
