EZGUI: 代码控制刷UIButton四态的贴图

    /// <summary>
    /// 新增物品Icon(不删除之前的icon)
    /// </summary>
    /// <param name="index">物品在packsprite中的index</param>
    /// <param name="button">物品所在控件</param>
    public void AddItemIcon(int index, AutoSpriteControlBase button, PackedSprite sprites)
    {
        SPRITE_FRAME mySpriteFrame = sprites.animations[0].GetFrame(index);
        UVAnimation uiAnimation = button.animations[0];//0:normal  1:over  2:active  3:disable
        uiAnimation.SetAnimFrame(0, mySpriteFrame);
        // Update mesh UVs:
        button.SetFrameInfo(mySpriteFrame);
    }

    /// <summary>
    /// 更新物品Icon(替换icon)
    /// </summary>
    /// <param name="index">物品在packsprite中的index</param>
    /// <param name="button">物品所在控件</param>
    public void UpdateItemIcon(int index, AutoSpriteControlBase button, PackedSprite sprites)
    {
        SPRITE_FRAME mySpriteFrame = sprites.animations[0].GetFrame(index);
        UVAnimation uiAnimation = button.GetCurAnim();
        uiAnimation.SetAnimFrame(0, mySpriteFrame);
        // Update mesh UVs:
        button.SetFrameInfo(mySpriteFrame);

    /// <summary>
    /// 删除物品Icon
    /// </summary>
    /// <param name="index">物品在packsprite中的index</param>
    /// <param name="button">物品所在控件</param>
    public void DeleteItemIcon(int index, AutoSpriteControlBase button, PackedSprite sprite)
    {
        SPRITE_FRAME mySpriteFrame = sprite.animations[0].GetFrame(index);
        UVAnimation uiAnimation = button.GetCurAnim();
        uiAnimation.SetAnimFrame(0, mySpriteFrame);
        button.SetFrameInfo(mySpriteFrame);
    }

PS：EZGUI的其他控制组件也可用。

在SpriteBase.cs脚本中添加这个方法：

/// <summary>
    /// 修改控件的某状态的图片 如：UIButton的四态
    /// </summary>
    /// <param name="index">状态索引</param>
    /// <param name="frameData">sprite frame</param>
    public void SetAnimFrame(int index, SPRITE_FRAME frameData)
    {
        Debug.LogError("frames.length=" + frames.Length);
        if (index < frames.Length)
        {
            frames[index] = frameData;
        }
    }
