嵌入式字体在Flex移动ActionBar中无法使用

我已经嵌入了一些字体并在我的移动应用程序中使用它们,除了我尝试用于“ActionBar”的那些外,它们都在工作.他们在其他地方工作,用“Comic Sans MS”代替“titleCGF”将其改为Comic Sans.那么为什么它不适用于我的自定义fontFamily？

<fx:Style>
        @namespace s "library://ns.adobe.com/flex/spark";
        @font-face {
            src: url("assets/Comic_Book.ttf");
            fontFamily: comic;
            embedAsCFF: false;
        }
/******************************
        @font-face{
            src: url("assets/CGF_Locust_Resistance.ttf");
            fontFamily: titleCGF;
            embedAsCFF: false;
        }
        @font-face{
            src: url("assets/CGF_Locust_Resistance.ttf");
            fontFamily: titleCGF;
            embedAsCFF: true;
        }
**********************************/
        .titleStyle{
            fontFamily: titleCGF;
            color: #FFFFFF;
        }
        .comicmessage{
            fontFamily: titleCGF;
            color: #838689;
            fontSize: 14;
        }
        s|IconItemRenderer{
            fontFamily: comic;
            color: #FEBA03;
            fontSize:18;
        }
        s|ActionBar{
            defaultButtonAppearance: beveled;
            accentColor: #FEBA03;
        }
        s|ActionBar #titleDisplay{
            fontFamily: "titleCGF";

        }
    </fx:Style>

这就是我得到的：

编辑：我试图制作自己的皮肤,部分预先编写的代码是这样的：

<!-- SkinParts
name=titleGroup,type=spark.components.Group,required=false
name=actionGroup,required=false
name=navigationGroup,required=false
name=titleDisplay,type=spark.core.IDisplayText,required=false
-->

当我尝试定义像前三个< s：Group ... />这样的东西时,它工作正常.但没有任何东西出现在spark.core.IDisplayText中. ie,< s：IDisplayText ... />什么都没有…

/* StyleableTextField,regular */
@font-face {
    src: url("assets/COMIC.TTF");
    fontFamily: "comic";
    embedAsCFF: false;
}

/* StyleableTextField,bold */
@font-face {
    src: url("assets/COMICBD.TTF");
    fontFamily: "comic";
    fontWeight: bold;
    embedAsCFF: false;
}

/* Label,regular */
@font-face {
    src: url("assets/COMIC.TTF");
    fontFamily: "comicCFF";
    embedAsCFF: true;
}

/* Label,bold */
@font-face {
    src: url("assets/COMICBD.TTF");
    fontFamily: "comicCFF";
    fontWeight: bold;
    embedAsCFF: true;
}

s|Label
{
    fontFamily: "comicCFF";
}

s|ActionBar
{
    fontFamily: "comic";
}

s|LabelItemRenderer
{
    fontFamily: "comic";
}
