C# unmanaged function pointers for iOS

C# unmanaged function pointers for iOS

Just a reminder to myself when I need this thing next time for making Unity work with native code:

  • delegate method should be static to please AOT compiler required for iOS

  • method should have have [MonoPInvokeCallback(typeof(YourDelegate))] attribute. its code is as simple as this:

    [AttributeUsage (AttributeTargets.Method)]
public sealed class MonoPInvokeCallbackAttribute : Attribute
{
    public MonoPInvokeCallbackAttribute (Type t) {}
}

  • for other platforms, delegate should have [UnmanagedFunctionPointer(YourCallingConvention)] attribute, but for iOS it prevents AOT compilation for some reason, so we need to #if it
