HarmonyOS 鸿蒙Next 全局支持iconfont字体图标

1、全局使用自定义字体，在EntryAbility.ets文件的onWindowStageCreate生命周期中，通过windowStage.loadContent回调注册

import font from '@ohos.font';
onWindowStageCreate(windowStage: window.WindowStage): void {
  windowStage.loadContent('pages/registerFont', (err, data) => {
    if (err.code) {
      return;
    }
    font.registerFont({
      familyName: 'iconfont',
      familySrc: $rawfile('AlimamaDaoLiTi.ttf')
    })
    font.registerFont({
      familyName: 'SF',
      familySrc: $rawfile('font/SF-Pro-Text-Italic.ttf')
    })
  });
}

2、registerFont.ets在页面中使用注册的字体familyName即可

@Entry
@Component
struct registerFont {
  @State message: string = 'test'
  build() {
    Column() {
      Text(this.message)
        .align(Alignment.Center)
        .fontSize(50)
        .fontFamily('iconfont')
      Text(this.message)
        .align(Alignment.Center)
        .fontSize(50)
        .fontFamily('SF')
    }.width('100%')
  }
}
