unity5x+UGUI屏幕自适应(多分配率适配)

1、Canvas的属性配置

2、Canvas Scaler的属性配置

3、根据不同的屏幕的比例动态修改缩放基准

 void Start ()
     {
         float standard_width = 960f;        //初始宽度
         float standard_height = 640f;       //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
         //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();
         if (adjustor == 0)
         {
             canvasScalerTemp.matchWidthOrHeight = 1;
         }
         else
         {
             canvasScalerTemp.matchWidthOrHeight = 0;
         }
     }

将脚本挂在画布控件上。
