确定是否使用React Native启用地理定位 [英] Determining if geolocation enabled with react native

问题描述

使用RN构建应用程序我使用以下方法来接收用户的位置:

Building an app with RN I use the following to receive user's location :

 navigator.geolocation.getCurrentPosition(
  (position) => {
   //do stuff with location
  },
  (error) => {
    //error or locaiton not allowed
  },
  {enableHighAccuracy: true, timeout: 20000, maximumAge: 1000}
);

哪个立即调用查询以使用户接受地理位置许可.我现在想要实现的是在提示用户单击按钮以接受那些权限之前，先有一个明确的屏幕.为了到达那里，我需要某种方式来检查他是否已经接受了这些权限.将其缓存在存储中将是一个糟糕的解决方案-如果用户更改设置的权限，则可能不同步.

Which immediately invokes the inquiry for user to accept geolocation permissions. What I'm trying to achieve now is to have an explicit screen before prompting user to click on a button to accept those permissions. In order to get there, I need some way to check if he has accepted those permissions before or not. Caching it in storage would be a bad solution - it might go out of sync if user changes permissions in settings.

如何在不触发权限警报的情况下检查用户是否已接受地理定位权限?

How can I check if user has accepted geolocation permissions without triggering the permission alert?

推荐答案

您可以使用此库 https ://github.com/yonahforst/react-native-permissions 检查用户是否已接受位置许可. 像这样:

You can use this library https://github.com/yonahforst/react-native-permissions to check if user has accepted location permission. Like this:

Permissions.getPermissionStatus('location')
  .then(response => {
    this.setState({ locationPermission: response })
  })
