Why requestWhenInUseAuthorization doesn't prompt the user for access to the location?

Solution 1:

You probably need to update your plist file. Here's a tutorial how to do it, quick & dirty:

You need to do is to add one of the following keys to your Info.plist file:

NSLocationWhenInUseUsageDescription

NSLocationAlwaysUsageDescription

You also need to request authorization for the corresponding location method, WhenInUse or Background. Use one of these calls:

[self.locationManager requestWhenInUseAuthorization]
[self.locationManager requestAlwaysAuthorization]

There's also a post that I found helpful:

Location Services not working in iOS 8

This answer details how to update your plist file:

Add one of the following lines to your info.plist

<key>NSLocationWhenInUseUsageDescription</key>
<string>The spirit of stack overflow is coders helping coders</string>

<key>NSLocationAlwaysUsageDescription</key>
<string>I have learned more on stack overflow than anything else</string>

You'll probably want to customize and spell-check the strings of the dictionary entry that goes in the info.plist file before shipping the code.
