Ionic + CreateJs高CPU和内存 [英] Ionic + CreateJs high CPU and Memory

问题描述

在带有createjs库的离子应用程序中，CPU和RAM使用量的增加给我带来了严重的问题。该问题导致该应用在一段时间后崩溃。
在每个页面都有一个新画布的页面之间导航时，我看到RAM和CPU急剧增加。
没有内存泄漏。我已经使用chrome开发人员工具对其进行了测试。

I have a serious problem with an increasing CPU and RAM usage in an ionic app with createjs library. The problem cause the app to crash after a while. As I am navigating between pages where each page has a new canvas, I see the RAM and CPU to dramatically increase. There is no memory leak. I have tested it with chrome developer tools.

推荐答案

经过如此多的测试，解决方案是将每个模板页面都处理为离子作为根页面。因此，当我导航到新模板页面时，我总是这样做：

After so so much testing, the solution was to treat each template page in ionic as a root page. So when I was navigating to a new template page I always did:

          $ionicHistory.nextViewOptions({
            historyRoot: true,
            disableBack: true
          });

          $ionicHistory.clearCache();
          createjs.Tween.removeAllTweens();
          $scope.stage.removeAllEventListeners();
          $scope.stage.removeAllChildren();
          $state.go("lesson", {}, {reload: true});

这样可以清除ionic保留的所有缓存，并清除createjs中的每个事件，补间动画和元素太。
这极大地提高了应用程序的速度！

This way all cache that ionic kept was cleared and every event, tween motion and element in createjs was cleared too. This increased the speed of the app drammatically!
