在一个AngularJS（1.2.7）项目，使用的UI路由器（0.2.8），我想申请的当前状态为一类到UI视图元素，因为这可以让我申请特定状态的动画，例如：做一个过渡，从登录要开始做转移B从开始去设置。

In a AngularJS (1.2.7) project, using UI Router (0.2.8), I want to apply the current state as a class to the ui-view element, because that would allow me to apply animations for specific states, e.g. do transition A going from login to start and do transition B going from start to settings.

目前，我对$ rootScope的$状态对象（如提到这里，这让我用纳克级=$ state.current.name在身体上添加一个基于状态的类。但是，如果我补充一点，到UI视图元素，如：

At the moment I have the $state object on the $rootScope (as mentioned here, which allows me to add a state-based class on the body using ng-class="$state.current.name". However, if I add that to the ui-view element, e.g.

<div ui-view ng-class="$state.current.name"></div>

那么类是一步背后的实际状态。因此，从登陆到开始走出去的时候，班级将登录，而不是启动。

Then the class is one step behind the actual state. So when going from "login" to "start", the class will be "login" instead of "start".

我觉得这是一个错误，你可以阅读更多关于这里的问题：

I think this is a bug, you can read more about the issue here:

直到它是固定的，我建议这样的解决方法：

Until it is fixed I suggest such a workaround:

<div ng-class="$state.current.name"><div ui-view></div></div>
