Unity设置AppIcon方法

制作unity自动打包工具时，不同的渠道需要不同的AppIcon，在网上找了方法，记录下

代码：

    public  void SetDefaultIcon()
    {
　　　　 Texture2D texture = AssetDatabase.LoadAssetAtPath(string.Format("Assets/AppIcon/{0}.png", "appicon"), typeof(Texture2D)) as Texture2D;
        MethodInfo getIconFormPlatform = typeof(PlayerSettings).GetMethod("GetIconsForPlatform", BindingFlags.NonPublic | BindingFlags.Static);
        MethodInfo getIconSizesForPlatform = typeof(PlayerSettings).GetMethod("GetIconSizesForPlatform", BindingFlags.NonPublic | BindingFlags.Static);
        MethodInfo setIconsForPlatform = typeof(PlayerSettings).GetMethod("SetIconsForPlatform", BindingFlags.NonPublic | BindingFlags.Static);
        Texture2D[] textureArray = (Texture2D[])getIconFormPlatform.Invoke(null, new object[] { string.Empty });
        var iconSizesForPlatform = (int[])getIconSizesForPlatform.Invoke(null, new object[] { string.Empty });
        if (textureArray.Length != iconSizesForPlatform.Length)
        {
            textureArray = new Texture2D[iconSizesForPlatform.Length];
            setIconsForPlatform.Invoke(null, new object[] { string.Empty, textureArray });
        } 
        setIconsForPlatform.Invoke(null, new object[] { string.Empty, textureArray });
        AssetDatabase.SaveAssets();
    }
