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：

 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<CanvasScaler>();  
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：
