1.Canvas的屬性配置：

2.Canvas Scaler的屬性配置：

3.根據不同的屏幕比例動態寫改碩放基準：

1 public float standard_width = 800f;        //初始宽度     2     public float standard_height = 480f;       //初始高度     3     float device_width = 0f;                //当前设备宽度     4     float device_height = 0f;               //当前设备高度     5     float adjustor = 0f;         //屏幕矫正比例     6     void Start()   7     {   8            9         //获取设备宽高    10         device_width = Screen.width;  11         device_height = Screen.height;  12         //计算宽高比例    13         float standard_aspect = standard_width / standard_height;  14         float device_aspect = device_width / device_height;  15         //计算矫正比例    16         if (device_aspect < standard_aspect)  17         {  18             adjustor = standard_aspect / device_aspect;  19         }  20   21         CanvasScaler canvasScalerTemp = transform.GetComponent
      
       ();  22         if (adjustor == 0)  23         {  24             canvasScalerTemp.matchWidthOrHeight = 1;  25         }  26         else  27         {  28             canvasScalerTemp.matchWidthOrHeight = 0;  29         }  30     }
      

4.將脚本挂在畫布上：

效果如圖：
