更新2：

当我输入背景，然后输入前景时，我将检查聊天是否已登录。使用以下条件：

[QBChat instance].isLoggedIn

（1）如果已登录，我会获取多个表

（2）如果没有，我创建会话并再次登录

我的猜测：进入后台一段时间之后，会话是否可能被破坏，而[QBChat实例] .isLoggedIn仍然返回YES？如果是这种情况，那么我该如何测试是否可以安全地获取表格？

进入前景后，屏幕始终在3秒内变黑。我试过iOS 6/7

注意：屏幕变黑，但应用程序不会崩溃。因为sendPresence计时器仍然每15秒滴答一次：

-[QBChat xmppStream:didSendPresence:] -> Presence: <presence/>

Answer 1

我通过在ChatDidLogin中注册推送通知而不是用户登录委托方法来解决了这个问题。

问题是登录使用将返回成功，即使已经登录，也会注册推送通知两次。但是，如果已登录，聊天将失败。

我的应用程序会不断检查服务器是否已通过

登录

+ (BOOL)isServerLoggedIn {
    return [QBChat instance].isLoggedIn;
}

如果没有登录，我再次与委托创建会话，然后在成功时登录用户，然后在成功时登录聊天。

编辑：此设计存在问题：

如果[QBChat实例] .isLoggedIn为true但QBUser未登录怎么办？如何检查QBUser是否已登录？

Answer 2

您可以单独登录聊天和REST服务。

要检查QBUser是否已登录 - 只需创建一个单独的变量并在委托中将其设置为YES：

// QuickBlox queries delegate
- (void)completedWithResult:(Result *)result{

    if(result.success){

        // User Login
        if([result isKindOfClass:QBUUserLogInResult.class]){

            self.userLoggedIn = YES;
        }
    }
}
