ionic 用户注销登录时,清空所有页面缓存

有人可能知道ionic的$ionicHistory是有一个清空缓存的命令的，命令如下：

 

clearHistory()

Clears out the app’s entire history, except for the current view.

   

但是此命令然并卵，所以我又看了一下API和源码发现了如下方法：

  

clearCache()

Removes all cached views within every ionNavView. This both removes the view element from the DOM, and destroy it’s scope.

• Returns: promise

 

 /**
     * @ngdoc method
     * @name $ionicHistory#clearCache
	 * @return promise
     * @description Removes all cached views within every {@link ionic.directive:ionNavView}.
     * This both removes the view element from the DOM, and destroy it's scope.
     */
    clearCache: function(stateIds) {
      return $timeout(function() {
        $ionicNavViewDelegate._instances.forEach(function(instance) {
          instance.clearCache(stateIds);
        });
      });
    },

 

API地址：http://ionicframework.com/docs/api/service/$ionicHistory/

源码地址：https://github.com/driftyco/ionic/blob/master/js/angular/service/history.js#L1

 

然后写了如下代码去清空页面缓存：

 

var views = $ionicHistory.viewHistory().views;
var stateIds = [];
for(var id in views){
      stateIds.push(views[id].stateId);
}
$ionicHistory.clearCache(stateIds).then(function(){
      $location.path('/login');//设置路由地址
})
