带有Expo的React-Native振动事件检测器 [英] React-Native Shake Event Detector With Expo

问题描述

我在iOS手机上使用的是 Expo v2.3.8 和 Expo客户端v2.9.0 .

我正在尝试测试摇晃 addEventListener 事件，但总是以Expo Expo开发者菜单打开而告终.因此我关闭了Expo中的"shake"选项，但是这一次，当我摇晃手机时，会打开电话旧的Expo开发者菜单.

I'm trying to test shake addEventListener event but always end up Expo developer menu opens. So I closed the shake option in Expo but this time when I shake, the phone old Expo developer menu opens.

这是我的代码:

import RNShake from 'react-native-shake';

export default class Starting extends Component {
    static navigationOptions = {
      title: 'MyApp',
    };

    componentWillMount() {
      RNShake.addEventListener('shake', () => {
        this.props.navigation.push('Register');
      });
    }

    componentWillUnmount() {
      RNShake.removeEventListener('shake');
    }
   .
   . 
   .
}

我尝试打开生产模式.它没有工作.如何通过世博会测试摇奖活动?React Native Shake Detector- https://www.npmjs.com/package/react-native-摇动

I tried turn on production mode. It didnt work. How can I test shake event with Expo? React Native Shake Detector - https://www.npmjs.com/package/react-native-shake

推荐答案

react-native-shake 库需要链接本机代码，因此，如果不先将它从Expo弹出到Expokit，它将无法工作此处: https://docs.expo.io/versions/latest/expokit/eject/

The react-native-shake library requires linking native code, so it will not work without first ejecting from Expo to Expokit as explained here: https://docs.expo.io/versions/latest/expokit/eject/

在您的项目目录中，运行 expo弹出.这将下载所需的依赖项，并在ios和android目录下构建本机项目.然后按照库安装说明运行 react-native链接react-native-shake .

From your project directory, run expo eject. This will download the required dependencies and build native projects under the ios and android directories. Then run react-native link react-native-shake as per the library install instructions.
