Solution with backward compatibility which doesn't produce Xcode warnings:

SEL requestSelector = NSSelectorFromString(@"requestWhenInUseAuthorization");
if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined &&
  [self.locationManager respondsToSelector:requestSelector]) {
((void (*)(id, SEL))[self.locationManager methodForSelector:requestSelector])(self.locationManager, requestSelector);
  [self.locationManager startUpdatingLocation];
} else {
  [self.locationManager startUpdatingLocation];
}

Setup NSLocationWhenInUseUsageDescription key in your Info.plist.

For iOS version 11.0+ : Setup NSLocationAlwaysAndWhenInUseUsageDescription key in your Info.plist. along with other 2 keys.

Don t forget to add NSLocationWhenInUseUsageDescription in MyApp-Info plist and give it a string          self locationManager     CLLocationManager alloc  init           self locationManager delegate   self             Check for iOS 8  Without this guard the code will crash with  unknown selector  on iOS 7          if   self locationManager respondsToSelector  selector requestWhenInUseAuthorization                   self locationManager requestWhenInUseAuthorization                      self locationManager startUpdatingLocation            Location Manager Delegate Methods         -  void locationManager  CLLocationManager   manager didUpdateLocations  NSArray   locations               NSLog         locations lastObject

In iOS 8 you need to do two extra things to get location working  Add a key to your Info plist and request authorization from the location manager asking it to start  info plist    lt key gt NSLocationUsageDescription lt  key gt   lt string gt I need location lt  string gt   lt key gt NSLocationAlwaysUsageDescription lt  key gt   lt string gt I need location lt  string gt   lt key gt NSLocationWhenInUseUsageDescription lt  key gt   lt string gt I need location lt  string gt    Add this to your code  if  IS OS 8 OR LATER         locationmanager requestWhenInUseAuthorization         locationmanager requestAlwaysAuthorization

To ensure that this is backwards compatible with iOS 7  you should check whether the user is running iOS 8 or iOS 7  For example    define IS OS 8 OR LATER     UIDevice currentDevice  systemVersion  floatValue   gt   8 0     In ViewDidLoad if IS OS 8 OR LATER        self locationManager requestAlwaysAuthorization       self locationManager startUpdatingLocation

Before  locationManager startUpdatingLocation    add an iOS8 location services request   if  locationManager respondsToSelector  selector requestAlwaysAuthorization         locationManager requestAlwaysAuthorization     Edit your app s Info plist and add key NSLocationAlwaysUsageDescription with the string value that will be displayed to the user  for example  We do our best to preserve your battery life    If your app needs location services only while the app is open  replace   requestAlwaysAuthorization with requestWhenInUseAuthorization and  NSLocationAlwaysUsageDescription with NSLocationWhenInUseUsageDescription

To Access User Location in iOS 8 you will have to add   NSLocationAlwaysUsageDescription in the Info plist    This will ask the user for the permission to get their current location

For those using Xamarin  I had to add the key NSLocationWhenInUseUsageDescription to the info plist manually since it was not available in the dropdowns in either Xamarin 5 5 3 Build 6 or XCode 6 1 - only  NSLocationUsageDescription was in the list  and that caused the CLLocationManager to continue to fail silently

I was pulling my hair out with the same problem  Xcode gives you the error      Trying to start MapKit location updates without prompting for   location authorization  Must call - CLLocationManager   requestWhenInUseAuthorization  or - CLLocationManager   requestAlwaysAuthorization  first    But even if you implement one of the above methods  it won t prompt the user unless there is an entry in the info plist for NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription   Add the following lines to your info plist where the string values represent the reason you you need to access the users location    lt key gt NSLocationWhenInUseUsageDescription lt  key gt   lt string gt This application requires location services to work lt  string gt    lt key gt NSLocationAlwaysUsageDescription lt  key gt   lt string gt This application requires location services to work lt  string gt    I think these entries may have been missing since I started this project in Xcode 5  I m guessing Xcode 6 might add default entries for these keys but have not confirmed    You can find more information on these two Settings here

I ended up solving my own problem  Apparently in iOS 8 SDK  requestAlwaysAuthorization  for background location  or requestWhenInUseAuthorization  location only when foreground  call on CLLocationManager is needed before starting location updates  There also needs to be NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription key in Info plist with a message to be displayed in the prompt  Adding these solved my problem   For more extensive information  have a look at  Core-Location-Manager-Changes-in-ios-8

According to the Apple docs    https   developer apple com documentation corelocation requesting permission to use location services https   developer apple com documentation corelocation cllocationmanager 1620562-requestwheninuseauthorization   As of iOS 8  the presence of a NSLocationWhenInUseUsageDescription or a NSLocationAlwaysUsageDescription key value in your app s Info plist file is required  It s then also necessary to request permission from the user prior to registering for location updates  either by calling  self myLocationManager requestWhenInUseAuthorization  or  self myLocationManager requestAlwaysAuthorization  depending on your need  The string you entered into the Info plist will then be displayed in the ensuing dialog   If the user grants permission  it s business as usual  If they deny permission  then the delegate is not informed of location updates

I was working on an app that was upgraded to iOS nbsp 8 and location services stopped working  You ll probably get and error in the Debug area like so   Trying to start MapKit location updates without prompting for location authorization  Must call - CLLocationManager requestWhenInUseAuthorization  or - CLLocationManager requestAlwaysAuthorization  first   I did the least intrusive procedure  First add NSLocationAlwaysUsageDescription entry to your info plist     Notice I didn t fill out the value for this key  This still works  and I m not concerned because this is a in house app  Also  there is already a title asking to use location services  so I didn t want to do anything redundant   Next I created a conditional for iOS 8   if   self locationManager respondsToSelector  selector requestAlwaysAuthorization            locationManager requestAlwaysAuthorization       After this the locationManager didChangeAuthorizationStatus  method is call   -  void locationManager  CLLocationManager   manager didChangeAuthorizationStatus    CLAuthorizationStatus status        self gotoCurrenLocation       And now everything works fine  As always  check out the documentation

I add those key in InfoPlist strings in iOS 8 4  iPad mini 2  It works too  I don t set any key  like NSLocationWhenInUseUsageDescription  in my Info plist     InfoPlist strings    NSLocationWhenInUseUsageDescription     I need GPS information           Base on this thread  it said  as in iOS 7  can be localized in the InfoPlist strings  In my test  those keys can be configured directly in the file InfoPlist strings      So the first thing you need to do is to add one or both of the   following keys to your Info plist file          NSLocationWhenInUseUsageDescription   NSLocationAlwaysUsageDescription         Both of these keys take a string which is a description of why you   need location services  You can enter a string like    Location is   required to find out where you are    which  as in iOS 7  can be   localized in the InfoPlist strings file      UPDATE   I think  IOS s method is better  Add key to Info plist with empty value and add localized strings to InfoPlist strings

Add key NSLocationWhenInUseUsageDescription or NSLocationAlwaysUsageDescription  background GPS use  with string asking to use GPS on each info plist from each target  Ask for permission by running    self initLocationManager locationManager     Where initLocationManager is      asks for GPS authorization on iOS 8 - void  initLocationManager  CLLocationManager    locationManager       locationManager     CLLocationManager alloc init        if  locationManager respondsToSelector  selector requestAlwaysAuthorization             locationManager requestAlwaysAuthorization       Remember that if the keys are not on each info plist for each target the app will not ask the user  The if provides compatibility with iOS 7 and the respondsToSelector  method guarantees future compatibility rather than just solving the issue for iOS 7 and 8

The problem for me was that the class that was the CLLocationManagerDelegate was private  which prevented all the delegate methods from being called  Guess it s not a very common situation but thought I d mention it in case t helps anyone

User · Answer

One common error for Swift developers   First make sure you add a value to the plist for either NSLocationWhenInUseUsageDescription or NSLocationAlwaysUsageDescription   If you are still not seeing a window pop up asking for authorization  look to see if you are putting the line var locationManager   CLLocationManager   in your View Controller s viewDidLoad method  If you do  then even if you call locationManager requestWhenInUseAuthorization    nothing will show up  This is because after viewDidLoad executes  the locationManager variable is deallocated  cleared out    The solution is to locate the line var locationManager   CLLocationManager   at the top of the class method
