Several Memory Optimization Questions

1. When compiling with stripping level: Use micro mscorlib I get the following error when clicking on the second button in my game when running on an iPhone 4s. I do not get the error in the simulator. Did I do something wrong or is it not possible to use that stripping level on iOS?

1. In the profiler, System.ExecutablesAndDlls is taking up 0.68 GB of memory. Is this normal? That’s about 70% of the total memory used.

2. My game is purely UI based. It doesn’t use the physics system at all. Is there any way I could optimize the game based on this?
