ios - Modify Assembly-CSharp.dll before send to IL2CPP in Unity3d

Question

I want to insert some code stub to Assembly-CSharp.dll by using Mono.Cecil before send to il2cpp when build iOS player with batchmode.

Currently, the only way I know is to wrap Unity\Editor\Data\Tools\UnusedByteCodeStripper2\UnusedBytecodeStripper2.exe to execute my patcher before real stripper.

Is there any other better way like [DidReloadScripts] to do this?

For Android, I can patch dlls after BuildPlayer. But for iOS with il2cpp, there is no dll generated before BuildPlayer.

Answer 1

Finally i wrote my own UnusedBytecodeStripper2 to replace the original one, and make the original one as part of process chain.
