我开始将我的 LIBGDX 应用程序移植到 IOS。我使用 libgdx 的 Xamarin studio 端口在 IOS 上运行我的应用程序。我移植成功，但应用程序无法在 Iphone Simulator 中加载 TextureAtlas 文件和 BitmapFont 文件。

我试过的代码是

   ...
    AssetManager assetManager = new AssetManager();
    assetManager.load("packer/help.txt", TextureAtlas.class);

    if (assetManager.update()) {

    }
    ...

上面的代码在桌面和 android 上运行良好，但在 Iphone Simulator 上运行时，我得到了以下日志。

我尝试将我的包扩展名从 .txt 更改为 .pack 但得到了相同的输出。

我无法在 Libgdx 论坛上找到解决方案。请赐教这个问题。

嘿，我发现了问题。

当我们从 Xamarin Studio 运行应用程序时，它不会打包所有项目。它留下了一些文件，如文本文件、xmls 等。我们需要标记它们以将它们包含在应用程序中。将所有这些文件标记为捆绑资源。

根据Badlogic 论坛上的这篇帖子，有几件事可能是错误的：

  • 您正在使用java.netAPI（可能不是您的情况）
  • 您正在使用Gdx.files.classpath加载一些文件
  • 您没有完全/正确地将资产打包到您的构建中。

仔细阅读Libgdx IOSWiki以了解警告并确保您已正确设置所有内容。

这个（类似的）问题：libgdx on ios GdxRuntimeException could't load file 已解决，因为 PNG 文件未正确优化。请参阅“PNG 优化”部分（并特别注意您正在使用的 Libgdx 版本，因为它的行为似乎已经改变）。
