小结：

1、EditorGUILayout的各种Field和GUILayout的类似，但是EditorGUILayout可以复制粘贴；

2、因为OnGUI是每帧执行的，EditorGUILayout中类似TextField、IntSlider、ColorField需要传一个值，返回修改值的，需要将返回值赋值给临时变量；

3、params GUILayoutOption[] options可以传的参数在GUILayout类中可以找到: GUILayout.Width, GUILayout.Height, GUILayout.MinWidth, GUILayout.MaxWidth, GUILayout.MinHeight, GUILayout.MaxHeight, GUILayout.ExpandWidth, GUILayout.ExpandHeight

4、DelayedField延迟的输入框 在按下回车键或将焦点从文本字段移开之前，不会返回新值。

以上就是EditorGUILayout中各种Field的用法了。
