使用React Native Expo监听位置服务的状态（非权限）

Question

假设用户使用的地图需要该位置处于活动状态，否则，该地图将被关闭。

是否可以使用Location.hasServicesEnabledAsync（）监听位置状态？

Answer 1

使用：

_getLocationAsync = async () => {
    let { status } = await 
Permissions.askAsync(Permissions.LOCATION);
    if (status !== 'granted') {
        alert('The request was denied');
    }else{
        try{
            let location = await Location.getCurrentPositionAsync({});
            // do something with location
         }catch(e){
            alert('We could not find your position. Please make sure your 
         location service provider is on');
            console.log('Error while trying to get location: ', e);
         }
    }
}
