在不知道你删除了什么的情况下，第二个问题很难解决......
我们只能说它指的是线51
AndroidJavaObject context = currentActivity.Call<AndroidJavaObject>("getApplicationContext");
最有可能currentActivity是null如果在 PC 上执行，因为50之前的行
AndroidJavaObject currentActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
在这种情况下可能不起作用。
第一个听起来像一个“错误”。
您可以将#if预处理器用作修补程序，以UNITY_IOS至少使编译器错误消失，例如

但是，不保证这可以解决您的所有问题。
Google Ads也有类似的错误并使用了相同的修补程序。
否则，您可能需要考虑安装 IOS 构建支持，我猜这也会使错误消失（但如果您只想为 Android 构建，当然会不必要地填充磁盘空间）
