iOS JIT issue with Actions.GetProperty
« on: January 15, 2014, 01:39:29 PM »
When I attempt to run my application on the iOS platform only, I get the following exception attempting to run a PlayMaker flow involving the GetProperty action:

ExecutionEngineException: Attempting to JIT compile method '(wrapper delegate-invoke) System.Reflection.MonoProperty/Getter`2<Interaction, UnityEngine.GameObject>:invoke_GameObject__this___Interaction (Interaction)' while running with --aot-only.

My understanding of this issue is that MonoProperty.GetValue() requires JIT reflection when executed under a .NET 2.0 runtime (it may have worked under .NET 1.1).  This presents a problem on AOT platforms, such as iOS, which don't support any form of dynamic compilation.  I have looked at other threads on this forum and google, and have verified the following settings:

Stripping Level: Disabled (my understanding is that this makes "link.xml" settings irrelevant).

Script Call Optimization: Slow and Safe

SymLink Unity Libraries: Enabled



I've found other method calls in the place of MonoProperty.GetValue() that would ostensibly accomplish the same purpose... but unfortunately the source for that function is under PlayMaker.dll, and I can't modify it.  I have been unable to find a workaround for this issue, occurring on iOS only.  Does anyone have any insight?

Thanks

Is it a specific property that's failing? Or any usage of GetProperty? I'll run some tests here too...

I was able to resolve this issue by setting my Api Compatibility level from .NET 2.0 to .NET 2.0 Subset.  PlayMaker appears to have a compatibility issue on the iOS platform when using the full .NET 2.0 assemblies.

Yes, I met this too. PlayMaker works good on desktop, but fail on ios. It thorws like below in XCode5.

** Trying to change comp-level to .NET subset now, but unfortunately there're too many refs using full .NET in my project.

Hi,

 yes, Custom action that access these properties will solve this issue. Basically you should avoid using Set and Get property actions to be IOS compatible with these settings.

bye,

Hi,

 I made a system to solve these problems. so now you'll be fine using these actions.

 Bye,
