问题 I'm using in my React Native App the navigator.geolocation.getCurrentPosition() function to get the location of my device but I have been reading that sometimes if the function notes that you have no good signal it could return the cached location. There is a way to avoid the returning cached location and return an error instead? 回答1: geolocation.getCurrentPosition(geo_success, [geo_error], [geo_options]); Use the option value in the function. You can use maximumAge maximumAge(ms) -positive

问题 Well , I have couple of topic related with this issue but still did not got the logic besides nobody provides a clear solution. Anyway, I will try to ask it again clearly and provide a screenshot (from a sample app) hope it would do the magic.
