Reflection not working properly with the IL2CPP backend

Just ran some tests and noticed that getting the properties for a transform at runtime on an iOS device only results in a few of its properties being returned, whereas the editor and android returns them all. It does however work fine when working with the Mono backend.

Does anybody know why this is not working? Or is reflection simply not supported fully by IL2CPP?

Code (CSharp):

1.         BindingFlags flags = BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance;
2.         PropertyInfo[] properties = transform.GetType ().GetProperties (flags);
3.         FieldInfo[] fields = transform.GetType ().GetFields (flags);
4.  
5.         print ("Properties");
6.  
7.         for (int i = 0; i < properties.Length; i++)
8.             print (properties [i].Name);
9.  
10.         print ("Fields");
11.  
12.         for (int i = 0; i < fields.Length; i++)
13.             print (fields[i].Name);
14.  
15.         print ("Test");
16.  
17.         PropertyInfo propertyInfo = transform.GetType ().GetProperty ("position", flags);
18.         propertyInfo.SetValue (transform, new Vector3 (2, 2, 2), null);

 

I think it's because stripping is done differently for iOS. Check this out here. This may or may not have anything to do with what you're seeing, as I don't build for iOS at all.

 

Yep, you're right. Adding a preserve all for UnityEngine solved the issue, but I'm not sure that is the best solution since I might not always need every unity class.

Thanks

 

Its pretty much impossible to have the ability to fully reflect on code and to have code stripping.
