使用 AWS Gamelift 的 Unity。编辑器很好，但构建到 IOS 时出现 NotSupportedException

Question

我完全卡住了。我的 unity 游戏在编辑器中运行良好，但在 IOS 上启动时崩溃。我正在将 AWS Gamelift 用于多人游戏，这可能是罪魁祸首，因为它在集成之前构建良好。对于实际的网络代码，我正在使用新的统一 DOTS 网络代码包。

在我的插件文件夹中，我有以下客户端 dll。

AWSSDK.CognitoIdentity
AWSSDK.CognitoIdentity提供商
AWSSDK.CognitoSync
AWSSDK.Core
AWSSDK.Extensions.CognitoAuthentication
AWSSDK.Gamelift
AWSSDK.Lambda
AWSSDK.SecurityToken
Microsoft.Bcl.AsyncInterfaces
System.Threading.Tasks.Extensions
log4net

在编辑器中一切运行完美。我可以连接到 GameLift，创建游戏会话等。当我构建时，它成功完成，但在启动时崩溃，显示一个带有天空盒的空场景，并且 Xcode 控制台中出现以下错误：

... some other outputs for initialization...

我怀疑这与 IOS 构建的代码剥离有关。我的 link.xml 文件如下（基于谷歌搜索，不知道我在这里做什么）。

奇怪的是，如果我删除保留 log4net.dll.

的行，我可以让程序启动

但是，这样做之后，当我单击登录到 gamelift 按钮时，出现了一个不同的错误，似乎缺少与 log4net 相关的内容。（我在注册和其他方面遇到了同样的错误）。奇怪的是，在我尝试使用 gamelift 之前，程序启动并运行良好。

这是 Xcode 中的不同错误。这是我尝试连接到 Cognito 以登录后唯一出现的内容。

所以因为这是一个类型初始化问题，所以我怀疑代码剥离有问题。但是我完全不懂代码剥离，这种预感只是基于我阅读的一些论坛帖子。

任何想法都会非常有帮助。我卡住了。

Answer 1

我用很多的难度和扎实的工作周设法解决了这个问题。这是我为修复它所做的步骤。以防以后其他人遇到问题。

确保我已经更新了 AWS SDK dll。我在 rider 中用 nuget 得到了这些，然后将 netstandard2.0 dll 拖到插件文件夹中。注意：仔细查看 nuget 中列出的依赖项。我必须使用稍旧版本的 AWS SDK 才能与 cognitoAuthentification.dll.

这是 rider 中的包的屏幕截图。包版本似乎很重要。仔细检查依赖项。

使用 Amazon.Extensions.CognitoAuthentication.dll 而不是 AWSSDK.Extensions.CognitoAuthentication.dll

删除 link.xml 文件中的所有内容。仅包含以下条目：

 <linker>
 <assembly fullname="AWSSDK.Core">
     <type fullname="Amazon.Util.Internal.PlatformServices.NetworkReachability" preserve="all"/>
     <namespace fullname="Amazon.Util.Internal.PlatformServices" preserve="all"/>
 </assembly>
 </linker>

检查所有其他插件，并逐一检查排除 iOS。首先，检查它是否破坏了编辑器中的桌面播放。然后检查它是否破坏了 iOS 构建中的任何内容。我认为这可能是最重要的一步。
进入unityeditor.app包内容，往下进入monobleedingedge/unityjit/拖拽Mono.Posix、System.Core、System.Configuration进入我的插件文件夹。

请注意，每次我更改 unity 插件文件夹中的 dll 时，我都必须重新启动 unity 以消除控制台错误和重新加载脚本失败。

如果有人好奇的话，这是我的插件文件夹的截图

无论如何...真正的答案是这不是一个用户友好的系统。

使用 AWS Gamelift 的 Unity。编辑器很好，但构建到 IOS 时出现 NotSupportedException
