Unity設置AppIcon方法

製做unity自動打包工具時，不一樣的渠道須要不一樣的AppIcon，在網上找了方法，記錄下

Unity4.6測試可用，Unity2017.2.0測試不可用

代碼：

    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 });
        } 
　　　　　textureArray[0] = texture;
        setIconsForPlatform.Invoke(null, new object[] { string.Empty, textureArray });
        AssetDatabase.SaveAssets();
    }

 本身摸索了下，折騰出2017下修改APPIcon方法

    private void _setDefaultIcon(string iconName)
    {
        Texture2D texture = AssetDatabase.LoadAssetAtPath(string.Format("Assets/Images/Icon/{0}.png", iconName),
            typeof(Texture2D)) as Texture2D;

        int[] iconSize = PlayerSettings.GetIconSizesForTargetGroup(BuildTargetGroup.Android);
        Texture2D[] textureArray = new Texture2D[iconSize.Length];
        for (int i = 0; i < textureArray.Length; i++)
        {
            textureArray[i] = texture;
        }
        textureArray[0] = texture;
        PlayerSettings.SetIconsForTargetGroup(BuildTargetGroup.Android, textureArray);
        AssetDatabase.SaveAssets();
    }
