在PropertyDrawer中，您不能使用来自GUILayout或EditorGUILayout的自动布局API，而只能使用来自GUI和EditorGUI的绝对Rect API始终传递相应的起始位置和维度。

你需要

• 计算显示嵌套内容所需的总高度
• 将此高度添加到public override float GetPropertyHeight，这将告诉检查员根据Rect保留以绘制您的财产
• 将为sub-editor保留的相应Rect传递到editor中，并在给定位置和尺寸处绘制

=>您不能简单地使用默认编辑器来实现这一点，因为它在PropertyDrawers无法使用的auto-layout系统中运行。
