UGUI研究院之设置全屏图

rectTransform.sizeDelta = new Vector2(Screen.width,Screen.height);

在UGUI中想设置一张全屏的背景图，但是直接设置 screen.width和screen.height后发现在有些分辨率下还是不能全屏。

把如下脚本挂在需要全屏的Image对象上即可。

using UnityEngine;using System.Collections; public class UIMaskLayer : MonoBehaviour{void Start(){int width = Screen.width;int height = Screen.height;int designWidth = 960;//开发时分辨率宽int designHeight = 640;//开发时分辨率高float s1 = (float)designWidth / (float)designHeight;float s2 = (float)width / (float)height;if(s1 < s2) {designWidth = (int)Mathf.FloorToInt(designHeight * s2);} else if(s1 > s2) {designHeight = (int)Mathf.FloorToInt(designWidth / s2);}float contentScale = (float)designWidth/(float)width;RectTransform rectTransform = this.transform as RectTransform;if(rectTransform != null){rectTransform.sizeDelta = new Vector2(designWidth,designHeight);}}}
