react-native中expo的真机测试字体不加载的坑

native-base的字体问题Roboto_medium

把native-base中的Fonts文件夹放到项目的根目录.

import {Font,AppLoading} from 'expo';
import {Root} from 'native-base';



export default class App extends React.Component {
  constructor(){
    super();
    this.state={
      loading:true
    }
  }
  async componentWillMount() {
    await Expo.Font.loadAsync({
      'Roboto': require('./Fonts/Roboto.ttf'),
      'Roboto_medium': require('./Fonts/Roboto_medium.ttf'),
    });
    this.setState({
      loading:false
    });

  }


render() {
    if(this.state.loading){
      return (
        <Root>
          <AppLoading/>
        </Root>
      )
    }

    return ()
}
