No, wrong issue 不，错误的问题

You have to memorize the current View he is in. As far as i remember, Ext has mechanisms for that, otherwise you can still use a (session-)cooke. 您必须记住他所处的当前View。据我所知，Ext具有实现该功能的机制，否则您仍然可以使用（session-）cooke。

and you don't have to start you application with the login-screen. 而且您不必从登录屏幕启动应用程序。 It is just one view, and imo. 这只是一个视图，而且是imo。 the one you would want to use as few as possible. 您想要使用的越少越好。

So. 所以。 on page load, check wether he is logged in, if no, show him the login-view, if yes check which view he was in and render it, otherwise send him to the start point. 在页面加载时，检查是否已登录（如果否），请向他显示登录视图，如果是，则检查他所处的视图并进行渲染，否则将其发送到起点。

this is basically the loop you have to send him through, on pageload, on refresh, onlogin, ... 基本上，这是您必须在页面加载，刷新，登录时向他发送的循环...
