Question

我在Adobe AIR 2.6 for Android中通过类链接加载SWF并访问其元素时遇到问题。如果有人知道，请帮助。

问题：
我有两个不同的.swf文件：

file1.swf（其中带有name1的MovieClip具有类链接'mainScreen'）
file2.swf（其中带有name2的MovieClip具有类链接'mainScreen'）

他们有一些动作脚本代码，我需要在我的应用程序域中导入。
文件下载很棒下载后，他们在不同的应用程序域中但是当我通过类链接获取元素并将它们添加到stage时 - 仅显示第二个加载的元素。看起来第二个具有相同类链接的动画片段取代了第一个。

为此我采用了这种方法：

请帮助我如何加载两个不同的元素SWF文件，这些文件具有相同类链接的元素，或解释为什么我不能这样做？当元素具有不同的类链接时 - 一切正常。但！！！它适用于网络，但对于空气，它不想工作。

Answer 1

我解决了我的问题，但我不知道为什么在Adobe AIR中是这样的：

使用URLLoader加载后，我正在使用Loader.loadbytes将SWF导入我的应用程序域，并使用Loader上下文。

var context2:LoaderContext = new LoaderContext(true);
        context2.checkPolicyFile = false;
        context2.allowCodeImport = true;

//if we comment this line of code - all works grate!      
//context2.applicationDomain = ApplicationDomain.currentDomain;

使用具有相同类链接问题的影片剪辑加载不同的swf
