我正在使用ui-router来嵌套状态和视图。当我单击链接时，URL会更改为该子状态的URL，但不会加载模板。

例如，当URL更改为substate时project/settings，project.settings.html不会加载相应的模板。

这是Plunkr提供的SSCCE

下面也是我的代码：

app.js

myApp.config(function ($stateProvider, $urlRouterProvider){
             $stateProvider
                  .state('project', {
                         url: "/project",
                         views:{
                         "content":{templateUrl: "partials/project.html"},
                         "header":{templateUrl: "partials/header"}
                         }
                       })

                  .state('project.settings', {
                          url: "/settings",
                          views:{
                           "content":{templateUrl: "partials/project.settings.html"},
                           "header":{templateUrl: "partials/header"}
                          }
                         }) 
            $urlRouterProvider.otherwise("/")                   
   });

    /* cheching whether the user is authentic or not*/


 myApp.run(function($rootScope,$location,$cookieStore,validateCookie,$state) {
      $rootScope.$on('$stateChangeStart',function(event,toState,toParams,fromState){
         if($cookieStore.get('user')){
            validateCookie.authService(function(result,error){
              if(!result){
                 $location.path("/");
              }else{
                $state.go('project.settings');
              }
            });   
         }
         else{
            $location.path("/"); 
         }
        });
    });

index.html

                <div ng-controller="userController">
                    <div ui-view="header"></div>
                    <div class="container" ui-view="content"></div>
                </div>

project.html

            <div ng-controller="userController">
                <div class="details">
                    <a ui-sref=".settings" class="btn btn-primary">Settings</a>
                </div>
            </div>

project.settings.html

        <h1>Project Setting -State test</h1>
