Problem with Protobuf on IOS

[BrokenHell]

When I build in IOS using Unity and run then I got this error log

The type initializer for 'com.nct.nplay.proto.SystemMessage' threw an exception.

(Filename: /Users/builduser/buildslave/unity/build/artifacts/generated/common/runtime/UnityEngineDebugBindings.gen.cpp Line: 37)

System.TypeInitializationException: The type initializer for 'com.nct.nplay.proto.gsystem' threw an exception. ---> System.NullReferenceException: A null value was found where an object instance was required.

Does anyone know what happen :( and how to fix it ? ( currently it can run well on android )

Thanks .

Currently I use version 2.4.1.555

I'm afraid we've seen various issues with Unity, some of which have been due to Unity runtime errors, and none of which are easily reproducible for someone who doesn't have Unity :(

If you're able to reproduce this with a desktop .NET console app (and sample data file) I'd be very happy to look into it - although I don't know when I'd make another release. (I'm more focused on the proto3 code, which doesn't support Unity...)
