一、新建一个脚本挂在主像机上

using UnityEngine;
using System.Collections;

public class GUILayoutLabelTest : MonoBehaviour {

    public Texture tex;

    void OnGUI()
    {
        GUI.Label(new Rect(10, 40, tex.width, tex.height), tex);//Label背景
        GUI.Label(new Rect(50, 60, tex.width, tex.height), "please enter account");//显示文本
    }
}

运行效果
