定位精度

这个Cordova/Phonegap插件用于Android和iOS，通过从应用程序内触发本地对话框来请求启用/更改位置服务，避免用户需要离开您的应用程序手动更改位置设置。
您可以通过以下命令安装：

$ ionic cordova plugin add cordova-plugin-request-location-accuracy
$ npm install --save @ionic-native/location-accuracy

则必须导入app.module.ts LocationAccuracy
用法

import { LocationAccuracy } from '@ionic-native/location-accuracy';

constructor(private locationAccuracy: LocationAccuracy) { }

...

this.locationAccuracy.canRequest().then((canRequest: boolean) => {

  if(canRequest) {
    // the accuracy option will be ignored by iOS
    this.locationAccuracy.request(this.locationAccuracy.REQUEST_PRIORITY_HIGH_ACCURACY).then(
      () => console.log('Request successful'),
      error => console.log('Error requesting location permissions', error)
    );
  }

});
