NSLocationAlwaysUsageDescription string added in info.plist is not showing in permission popup ios

问题

<key>NSLocationAlwaysUsageDescription</key>
    <array>
        <string>Location is required to find out where you are</string>
    </array>
    <key>Privacy-Location Usage Description</key>
    <string>Location is required to find out where you are.</string>

I have added this in info.plist. Still the permission popup does not shows the string added,Instead it shows-- Allow "app" to access your location even when you are not using the app?

回答1:

Use CLLocationManager

• Add the following line in your Info.plist file (right clic -> Open as -> Source Code)

  <key>NSLocationAlwaysUsageDescription</key>
  <string>Your explanation</string>
  

• Add the CLLocationManagerDelegate to your swift file

  class ViewController: UIViewController, CLLocationManagerDelegate {...}
  

• In your viewDidLoad() function, write the following lines :

  var locationManager : CLLocationManager = CLLocationManager()
  locationManager.delegate = self
  locationManager.requestAlwaysAuthorization()
  

It should work ! Hope I helped you !
