在 Exponent react-native 框架中使用 ShoutemUI/TextInput 组件时出现字体加载错

Question

我正在尝试将 shoutem/ui 与指数一起使用，但使用 shoutem/ui 文本输入组件时遇到错误，我收到以下错误消息fontFamily Rubik is not a system font and has not been loaded through Exponent.Font.loadAsync

但是，我加载了博客文章中列出的所有自定义shoutem字体 https://blog.getexponent.com/using-react-native-ui-toolkits-with-exponent-3993434caf66#.iyiwjpwgu

使用 Exponent.Font.loadAsync 方法。

 fonts: [
          FontAwesome.font,
          {'space-mono': require('./assets/fonts/SpaceMono-Regular.ttf')},
          {'Rubik-Black': require('./node_modules/@shoutem/ui/fonts/Rubik-Black.ttf')},
          {'Rubik-BlackItalic': require('./node_modules/@shoutem/ui/fonts/Rubik-BlackItalic.ttf')},
          {'Rubik-Bold': require('./node_modules/@shoutem/ui/fonts/Rubik-Bold.ttf')},
          {'Rubik-BoldItalic': require('./node_modules/@shoutem/ui/fonts/Rubik-BoldItalic.ttf')},
          {'Rubik-Italic': require('./node_modules/@shoutem/ui/fonts/Rubik-Italic.ttf')},
          {'Rubik-Light': require('./node_modules/@shoutem/ui/fonts/Rubik-Light.ttf')},
          {'Rubik-LightItalic': require('./node_modules/@shoutem/ui/fonts/Rubik-LightItalic.ttf')},
          {'Rubik-Medium': require('./node_modules/@shoutem/ui/fonts/Rubik-Medium.ttf')},
          {'Rubik-MediumItalic': require('./node_modules/@shoutem/ui/fonts/Rubik-MediumItalic.ttf')},
          {'Rubik-Regular': require('./node_modules/@shoutem/ui/fonts/Rubik-Regular.ttf')},
          {'rubicon-icon-font': require('./node_modules/@shoutem/ui/fonts/rubicon-icon-font.ttf')},
        ],
      });

浏览代码，我找不到明显的修复程序 - 甚至无法找到样式设置为抛出错误的位置。

Answer 1

上面的代码似乎缺少一行。尝试将此行添加到数组列表中：

{'Rubik': require('./node_modules/@shoutem/ui/fonts/Rubik-Regular.ttf')}

Answer 2

从链接使用此代码

import React, { Component } from 'react';
import { StatusBar } from 'react-native';
import { Font, AppLoading } from 'expo';
import { View, Examples } from '@shoutem/ui';
export default class App extends React.Component {
  state = {
    fontsAreLoaded: false,
  };
  async componentWillMount() {
    await Font.loadAsync({
      'Rubik': require('./node_modules/@shoutem/ui/fonts/Rubik-Regular.ttf'),
      'Rubik-Black': require('./node_modules/@shoutem/ui/fonts/Rubik-Black.ttf'),
      'Rubik-BlackItalic': require('./node_modules/@shoutem/ui/fonts/Rubik-BlackItalic.ttf'),
      'Rubik-Bold': require('./node_modules/@shoutem/ui/fonts/Rubik-Bold.ttf'),
      'Rubik-BoldItalic': require('./node_modules/@shoutem/ui/fonts/Rubik-BoldItalic.ttf'),
      'Rubik-Italic': require('./node_modules/@shoutem/ui/fonts/Rubik-Italic.ttf'),
      'Rubik-Light': require('./node_modules/@shoutem/ui/fonts/Rubik-Light.ttf'),
      'Rubik-LightItalic': require('./node_modules/@shoutem/ui/fonts/Rubik-LightItalic.ttf'),
      'Rubik-Medium': require('./node_modules/@shoutem/ui/fonts/Rubik-Medium.ttf'),
      'Rubik-MediumItalic': require('./node_modules/@shoutem/ui/fonts/Rubik-MediumItalic.ttf'),
      'Rubik-Regular': require('./node_modules/@shoutem/ui/fonts/Rubik-Regular.ttf'),
      'rubicon-icon-font': require('./node_modules/@shoutem/ui/fonts/rubicon-icon-font.ttf'),
    });
    this.setState({ fontsAreLoaded: true });
  }
  render() {
    if (!this.state.fontsAreLoaded) {
      return <AppLoading />;
    }
    return (
      <View styleName="flexible">
        <Examples />
        <StatusBar barStyle="default" hidden={false} />
      </View>
    );
  }
}
