Find all objects inside unity

Test when found a very strange bug, the object in the prefab of the property actually constantly in the change, the last step of debugging only found that the difference is to find the object of the API, hereby recorded

Two types of APIs

Canvas[] Canvasarray = (canvas[]) object.findobjectsoftype (typeof(Canvas));

Find only objects in the current scene

It's all over the Internet.

Canvas[] Canvasarray = (canvas[]) Resources.findobjectsoftypeall (typeof(Canvas));

Reources inside will find in addition to the scene, there are prefab inside the object, the modification of the property will affect prefab
