How do I set a global exception catcher in unity?

once my code throws out an self-defined exception like
PrefabNullException

codes of loading prefab are everywhere, I dont want set a catcher for them individually, that would be ugly and inconvenient........so is there any way to set a global catcher for them?

 

Instead of loading it with a Unity method, you may create your own one which can replace all the Unity ones. In there you can also use try+catch around the Unity method.

 

thx,I have already find another way to solve my problem..
