[CustomEditor(typeof(NewBehaviourScript))]
public class testEditor : Editor {
    /// 

    /// 挂载在物体上的脚本
    /// 
    private NewBehaviourScript nb;
    /// 

    /// 脚本数据
    /// 
    private List data = new List();

    private ReorderableList _list;

    private void OnEnable()
    {
        nb = target as NewBehaviourScript;
        data = nb.GetList;

        _list = new ReorderableList(data, typeof(GameObject), true, false, false, false);

        _list.drawElementCallback = (rect, index, isActive, isFocused) => {
            EditorGUI.ObjectField(rect, data[index].name, data[index], data[index].GetType(), true);
        };

        _list.drawHeaderCallback = rect => {
            GUI.Label(rect, "列表");
        };
    }

    public override void OnInspectorGUI()
    {
        base.OnInspectorGUI();
        _list.DoLayoutList();
    }
