unity之UGUI屏幕分辨率調整

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：

 public float standard_width = 800f;        //初始宽度
     public float standard_height = 480f;       //初始高度
     float device_width = 0f;                //当前设备宽度
     float device_height = 0f;               //当前设备高度
     float adjustor = 0f;         //屏幕矫正比例
     void Start()
     {  

         //获取设备宽高
         device_width = Screen.width;
         device_height = Screen.height;
         //计算宽高比例
         float standard_aspect = standard_width / standard_height;
         float device_aspect = device_width / device_height;
         //计算矫正比例
         if (device_aspect < standard_aspect)
         {
             adjustor = standard_aspect / device_aspect;
         }  

         CanvasScaler canvasScalerTemp = transform.GetComponent<CanvasScaler>();
         if (adjustor == )
         {
             canvasScalerTemp.matchWidthOrHeight = ;
         }
         else
         {
             canvasScalerTemp.matchWidthOrHeight = ;
         }
     }  

4.將脚本挂在畫布上：

效果如圖：
