How to use user’s location in your app?
there are two more settings
(1)click the project-> Build Phases -> link Binary With Libraries -> click “+” -> search for “location” -> click the CoreLocation.framework, import the library to your project
(2)find info.plist,and add two keys and values
the first key is :NSLocationWhenInUseUsageDescription, you can put whatever you want in the value field to explain your reason to request user location,such as"Because I want to know where you are”. this can help you to request user location when the app is running.
the second key is:NSLocationAlwaysUsageDescription,you can puts reasons in the value field such as”Because I always want to know your locations”,this can help you in any time to get the user location ,even the app is not running.
