问题：s:Label 上的点击和触摸事件性能不佳。

我使用最新的 air 版本和 Flash Builder 4.6 来开发一个移动应用程序。

这是代码：

<s:Group horizontalCenter="10" top="200">
    <s:VGroup>
        <s:VGroup id="wortundtafelstriche">
            <s:HGroup id="wortalign" >
                <s:Label id="wort1" visible="false" textAlign="center" width="43" color="0xffffff"  />
                <s:Label id="wort2" visible="false" width="30" color="0xffffff"  />
                <s:Label id="wort3" visible="false" width="30" color="0xffffff"  />
                <s:Label id="wort4" visible="false" width="30" color="0xffffff"  />
                <s:Label id="wort5" visible="false" width="30" color="0xffffff"  />
                <s:Label id="wort6" visible="false" width="30" color="0xffffff"  />
                <s:Label id="wort7" visible="false" width="30" color="0xffffff"  />
                <s:Label id="wort8" visible="false" width="30" color="0xffffff"  />
                <s:Label id="wort9" visible="false" width="30" color="0xffffff"  />
                <s:Label id="wort10" visible="false" width="30" color="0xffffff"  />
                <s:Label id="wort11" visible="false" width="30" color="0xffffff"  />
            </s:HGroup>
            <s:HGroup id="tafelalign">

        </s:VGroup>

    </s:VGroup>
</s:Group>

点击事件的作用：

        protected function makeunvisible(obj:Object):void
        {
            obj.visible = false;
        }

这很简单。

如果有人点击一个字母（s:Label），该字母应该是不可见的。

令人沮丧的事实是，当我单击一个字母时，并不总是调用 make invisible 方法。

有时我必须点击十次才能调用该方法。

我也尝试了触摸事件，但没有更好的结果......

在 Flex 框架中，与第一个触摸事件一起发送一个鼠标事件，并且只使用鼠标事件。与 Flash 世界中的大多数按钮一样，您的文本可能没有背景，因此它们只能使用非常细的实际字体轮廓来捕捉鼠标。

尝试将标签添加到容器中或设置它们的背景颜色。

PS它是不可见的而不是不可见的。
