在运行时资源中使用字体-actionscript3

刚刚找到答案。导入时需要注册字体。

private function onComplete(evt:Event):void {

  var loaderInfo:LoaderInfo = evt.target as LoaderInfo;

  loaderInfo.removeEventListener(
    Event.COMPLETE,
    onComplete
  );

  var appDomain:ApplicationDomain = loaderInfo.applicationDomain;

  var thisIsMyFont:Class;

  try {

    thisIsMyFont = appDomain.getDefinition(
      "ThisIsMyFont"
    ) as Class;

  } catch(ex:Error) {

    throw new Error(
      "The font could not be found!"
    );

  }

  Font.registerFont(thisIsMyFont);

  trace(
    "Now there are " + Font.enumerateFonts().length + " fonts available"
  );

}
