在设备上 运行 时出错，而不是在 Unity 编辑器中
Error when running on device, not in Unity editor
我正在尝试通过 Xcode 将我的游戏的新版本上传到我的 iPhone。使用此应用程序之前这不是问题，但现在我确实遇到了问题。
所以我创建了一个新的较小的项目来测试。它在编辑器中有效，但在上传到我的 iPhone (IOS) 时无效。
我是运行Unity 2021.2.7f1 Apple Silicon。
问题与某些缺少的模块有关，因此我无法从 IOS 打开数据库。
我认为它看起来像是打开数据库的东西，但我不确定。确保数据库复制到“Application.persistentDataPath”路径。
我是运行Unity 2021.2.7f1 Apple Silicon。
"dbconn.Open();"是它在 IOS 而不是 Mac 上失败的地方。我还没有在 Android.
上测试过

我终于根据上面的post解决了这个问题，见我评论中的线程。来自 Baydogan 的评论：
我终于找到了解决方法，直到 unity 修复了这个错误。
- 不要修改任何统一编辑器文件。像往常一样为 iOS 构建。
- 在 xcode 项目中搜索“// System.Void System.Runtime.InteropServices.CriticalHandle::Cleanup()”。
- 在下面移动几行并注释掉开头的行：“Marshal_SetLastWin32Error_”
- 完成
