要求新的应用程序许可

Question

I added a feature in my app that requires the background location permission on ios. How do I re-request the location permission to allow 'Always' vs 'While Using'?

Clarification: My app already requests the 'While Using' permission level. With the new feature I need users to up the permission to be 'Always'. However, right now when installing the update over a pre-existing app, ios isn't promiting the higher level permission and the only way to change it is by going into the Settings app.

Answer 1

Add to the /platforms/ios/{project}/{project}-Info.plist file these lines:

<key>NSLocationAlwaysUsageDescription</key>
<string>[App Name] would like to access your location when running.</string>

For 'While Using' your key has to be: NSLocationWhenInUseUsageDescription .

Answer 2

The way I solved this was to check if the permission is not set to 'Always'. Then if it's not, explain to the user why it needs to be set to 'Always' and then linking them to their settings to change it.

As far as I can tell there is no real way to re-trigger asking for a higher permission on iOS.
