requestAlwaysAuthorization not showing permission alert

Question

I'm trying to use some fancy iBeacons without success, kCLAuthorizationStatusNotDetermined all time. According to other questions it's a requirement to add those keys to info.plist (some questions says one, other says both). According to an article for iBeacons I need the Always option.

<key>NSLocationWhenInUseUsageDescription</key>
<string>Nothing to say</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>Permiso para acceder siempre</string>

At viewDidAppear:

self.locManager = [[CLLocationManager alloc]init];
self.locManager.delegate = self;
[self.locManager requestAlwaysAuthorization];
NSUUID* region1UUID = [[NSUUID alloc]initWithUUIDString:@""]; //ibeacon real UUID between "". Checked it's not nil.

self.beaconRegion = [[CLBeaconRegion alloc]
                                initWithProximityUUID:proximityUUID
                                identifier:@"myCoolString"];

self.beaconRegion.notifyEntryStateOnDisplay = YES;
self.beaconRegion.notifyOnEntry = YES;
self.beaconRegion.notifyOnExit = NO;
[self.locManager startMonitoringForRegion:self.beaconRegion];
[self.locManager startRangingBeaconsInRegion:self.beaconRegion];

Icon didn't appear at Settings/Privacy/Location until it was executed one of the two last methods. The Alert View to approve permissions never appears. If I perform a manual change at Location Settings and check it it will change status but at a few moments later Location at Settings will delete "Always" status for my app and will leave it blank again. Later I check with no luck

-(void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status {

Any ideas what is missing or wrong? Thank you

For iOS 11 developers, you should take a look at this post: Location Services not working in iOS 11.

TL;DR: you need ALL THREE location keys in the Info.plist:

<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>...</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>...</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>...</string>

Along with InfoPlist.strings translations in case of multilingual apps.
