如何让 Font-Face 在 iOS 上加载字体？

Question

我正在使用 Gatsby.js、Styled-Components 和名为 'Montserrat' 的自定义字体构建网站。构建时和热重载时为桌面浏览器加载字体。它没有在移动 iOS 上加载（我无权访问 Android）。我想弄清楚哪里出了问题。

我试过：

使用 Google 字体；
使用直接 url 从文件路径导入；
使用js导入文件路径；
对每种字体使用单独的字体调用。

我已经阅读了几个关于 SO 的问题并进行了搜索 Google 但大多数结果都是一般格式问题或我已经尝试过的问题。

这是我的 main.js 导入本地字体的地方：

import { createGlobalStyle } from 'styled-components';
import theme from './theme';
import * as MontserratRegularEOT from './fonts/MontserratRegular.eot';
import * as MontserratRegularOTF from './fonts/MontserratRegular.otf';
import * as MontserratRegularTTF from './fonts/MontserratRegular.ttf';
import * as MontserratRegularWOFF from './fonts/MontserratRegular.woff';
import * as MontserratRegularWOFF2 from './fonts/MontserratRegular.woff2';
import * as MontserratBoldEOT from './fonts/MontserratBold.eot';
import * as MontserratBoldOTF from './fonts/MontserratBold.otf';
import * as MontserratBoldTTF from './fonts/MontserratBold.ttf';
import * as MontserratBoldWOFF from './fonts/MontserratBold.woff';
import * as MontserratBoldWOFF2 from './fonts/MontserratBold.woff2';
const MainStyle = createGlobalStyle`

@charset "utf-8";

/*

*/

@font-face {
  font-family: 'Montserrat';
  src: local('Montserrat'), url(${MontserratRegularEOT}), /* IE9 Compat Modes */
  src: local('Montserrat'), url(${MontserratRegularOTF}) format('embedded-opentype'), /* IE6-IE8 */
  src: local('Montserrat'), url(${MontserratRegularWOFF2}) format('woff2'), /* Super Modern Browsers */
  src: local('Montserrat'), url(${MontserratRegularWOFF}) format('woff'), /* Pretty Modern Browsers */
  src: local('Montserrat'), url(${MontserratRegularTTF}) format('truetype'); /* Safari, Android, iOS */
  font-weight: normal;
  font-style: normal;
}

@font-face {
  font-family: 'Montserrat';
  src: local('Montserrat'), url(${MontserratBoldEOT}), /* IE9 Compat Modes */
  src: local('Montserrat'), url(${MontserratBoldOTF}) format('embedded-opentype'), /* IE6-IE8 */
  src: local('Montserrat'), url(${MontserratBoldWOFF2}) format('woff2'), /* Super Modern Browsers */
  src: local('Montserrat'), url(${MontserratBoldWOFF}) format('woff'), /* Pretty Modern Browsers */
  src: local('Montserrat'), url(${MontserratBoldTTF}) format('truetype'); /* Safari, Android, iOS */
  font-weight: bold;
  font-style: normal;
}

/*== 1 HTML Elements ==*/
html, body, div, span, applet, object, iframe,
h1, h2, h3, h4, h5, h6, p, blockquote, pre,
a, abbr, acronym, address, big, cite, code,
del, dfn, em, img, ins, kbd, q, s, samp,
small, strike, strong, sub, sup, tt, var,
b, u, i, center,
dl, dt, dd, ol, ul, li,
fieldset, form, label, legend,
table, caption, tbody, tfoot, thead, tr, th, td,
article, aside, canvas, details, embed,
figure, figcaption, Newsletter, header, hgroup,
menu, nav, output, ruby, section, summary,
time, mark, audio, video {
  font-family: 'Montserrat', san-serif !important;
}`

这是一个示例组件（我在这里删除了一些样式以提高可读性），它应该使用字体但不会在移动设备上加载它：

import React from 'react'
import styled from 'styled-components'
import Img from 'gatsby-image'
import {Row, Col} from 'react-bootstrap';

// other styles

const Headline = styled.h4`
  padding-top: 80px;
  color: ${props => props.theme.colors.base}; 
  font-size: 33px; 
  @media (max-width: 475px) {
    font-size: 1.6875rem; 
    padding-top: 0px;
  }
`

// other styles

const MainCardBlock = (props) => {
  return (
      <MainCard>
        <Col sm={6} className={'main-image-block'}>
          <Image fluid={props.mainCard.cardImage.fluid} backgroundColor={'#eeeeee'} />
        </Col>
        <TextContainer sm={6}>
          <Headline>{props.mainCard.headline}</Headline>
          <Excerpt dangerouslySetInnerHTML={{
                __html: props.mainCard.textBlock.childMarkdownRemark.html,
              }}
          mainCard/>
        </TextContainer>
      </MainCard>
    )
}

export default MainCardBlock

目前，加载 'san-serif' 而不是 'Montserrat'。我期待 <h4 class="MainCardBlock__Headline-sc-6x7ja9-2 eLajVr">Quality. Value.</h4>* 使用 'Montserrat' 但它使用 'san-serif'.

*<Headline>{props.mainCard.headline}</Headline>

这是它当前的编译方式：

            @font-face {
                font-family: 'Montserrat';
                src: local('Montserrat'),url(/static/MontserratRegular-cf004f9f3076d2c5af3d93c4740e9a9c.eot), src:local('Montserrat'),url(/static/MontserratRegular-a53070e1dc5d0a6703a83f9a8d1a81d5.otf) format('embedded-opentype'), src:local('Montserrat'),url(/static/MontserratRegular-a34a420be1193527133f0a7c11ef1113.woff2) format('woff2'), src:local('Montserrat'),url(/static/MontserratRegular-4fff79a005c63b70ee3334d23fd147bc.woff) format('woff'), src:local('Montserrat'),url(/static/MontserratRegular-b26b6d576dafd8c4a9d9415d69ca175c.ttf) format('truetype');
                font-weight: normal;
                font-style: normal;
            }

            @font-face {
                font-family: 'Montserrat';
                src: local('Montserrat'),url(/static/MontserratBold-5fbc4fa26dc4dbd1759d01f72999e029.eot), src:local('Montserrat'),url(/static/MontserratBold-373b1bb1af0fd36999b5027121559d3e.otf) format('embedded-opentype'), src:local('Montserrat'),url(/static/MontserratBold-58fe2032a07491d722704318e649acba.woff2) format('woff2'), src:local('Montserrat'),url(/static/MontserratBold-2c6fd139d7caa7583c6342a4a21fe4b3.woff) format('woff'), src:local('Montserrat'),url(/static/MontserratBold-e7b037f6d6fe39b886ecae436be231e5.ttf) format('truetype');
                font-weight: bold;
                font-style: normal;
            }

快速理论：Sans-serif 在 css 的 body 元素上拼写错误，h4 继承自该元素。由于拼写错误，css 的整行是否可能在 iOS 上被忽略？（尝试sans-serif）
