I am using iBeacons, but am running into a small problem.
On first use the user needs to give permission, we then following is called:
_locationManager = [[CLLocationManager alloc] init];
_locationManager.delegate = self;
[_locationManager requestAlwaysAuthorization];
However, I expected the following delegate method to be called:
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status {
NSLog(#"Auth status changed: %i", status);
if(status > 3){
// Check if we have to start monitoring beacons
NSLog(#"Do we need to initialise after auth given?");
//[self initialiseLocations];
}
}
I am running iOS 8.0.2, so not sure if this is a bug
This answer might help... it solved it for me at least. Also this website was a good walkthrough for this issue as well.
It looks like you are calling the requestAlwaysAuthorization correctly, but do you call startUpdatingLocation anywhere? Also, double check that in your Info.plist you have the appropriate key and string value added (NSLocationAlwaysUsageDescription since you're using requestAlwaysAuthorization).

I have an app that I am trying to get the authorization for LocationManager to show up. I had it working for Always but then tried When In Use. Now I can't get either one to work
I have Placed
NSLocationWhenInUseUsageDescription string enable to play
in my Info.plist
In my app delegate I have put
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.locationManager = [[CLLocationManager alloc]init];
self.locationManager.delegate= self;
return YES;
}
- (void)locationManager:(CLLocationManager *)manager
didChangeAuthorizationStatus:(CLAuthorizationStatus)status{
if([CLLocationManager authorizationStatus]==kCLAuthorizationStatusAuthorized){
NSLog(#"ok");
}
if([CLLocationManager authorizationStatus]==kCLAuthorizationStatusAuthorizedAlways){
NSLog(#"Always");
}
if([CLLocationManager authorizationStatus]==kCLAuthorizationStatusAuthorizedWhenInUse){
NSLog(#"WhenInUse");
}
if([CLLocationManager authorizationStatus]==kCLAuthorizationStatusRestricted){
NSLog(#"restricted");
}
if([CLLocationManager authorizationStatus]==kCLAuthorizationStatusDenied){
NSLog(#"denid");
AlertView2 = [[UIAlertView alloc] initWithTitle:#"App Permission Denied"
message:#"Please go to Settings/Privacy/Location Services to enable Always for this app to function properly."
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[AlertView2 show];
}
if([CLLocationManager authorizationStatus]==kCLAuthorizationStatusNotDetermined){
NSLog(#"undetermined");
[self.locationManager requestWhenInUseAuthorization];
}
}
I'm not sure this is what I had originally but I have tried every possible configuration, although obviously not.
Can someone help me get this thing working. I would prefer WhenInUse but at this point I'll take anything
By the way I do get a call back of the NSLog undetermined in the last status but the included code is not called.
Thanks for any help.
A couple of thoughts:
I'd suggest setting the delegate before you request permission.
What is authorizationStatus before you request permission? You should check it before you bother to request permission, because if they already refused permission, you want to tell them to fix settings. A request for permission will not result in anything (including a change in status) if permission was previously denied.
Try This .....
locationManager = [[CLLocationManager alloc]init];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = 1000.0f;
[locationManager requestAlwaysAuthorization];
[locationManager requestWhenInUseAuthorization];
[locationManager startUpdatingLocation];
So I am officially an idiot.
I looked at my info.plist and there it was. I had copied and pasted the Alway Description and changed it to WhenInUse and the when it didn't work I deleted the original and kept the copy and changed it back to Always. However upon expanding the column to see the whole thing the was a -2 attached to the end so it wasn't formatted correctly so it didn't work. Once I removed the -2 it works wonderful. I have changed the original post to show how it works. Thanks for all your help and I will make sure I address the concern you brought up.
I am trying to get authorization from user before fetching his location. I am using this code for that:
self.locationManager = [[CLLocationManager alloc] init];
[self.locationManager setDelegate:self];
if ([self.locationManager respondsToSelector:#selector(requestAlwaysAuthorization)]) {
// iOS8+
// Sending a message to avoid compile time error
[self.locationManager requestAlwaysAuthorization];
}
[self showIndicatorView];
self.getCityService = [[GetCitiesService alloc] initServiceWithDelegate:self isLocalCall:NO];
[self.getCityService fetchCities];
I see the alert on screen but before I allow it or not, it disappear form screen and app is not authorized.
I want my code to stop until user gives permission.
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.
Hope it helps someone else.
EDIT: For more extensive information, have a look at: http://nevan.net/2014/09/core-location-manager-changes-in-ios-8/
You code looks really weird, since you seem to be calling the requestAlwaysAuthorization twice. Once on self.locationManager and once via the sendAction.
You code should look like:
self.locationManager = [[CLLocationManager alloc] init];
[self.locationManager setDelegate:self];
if ([self.locationManager respondsToSelector:#selector(requestAlwaysAuthorization)]) {
// iOS8+
// Sending a message to avoid compile time error
[self.locationManager requestAlwaysAuthorization];
}
Here's the code snippet. Below.
// Initialize the region with the Estimote iBeacon manually generated UUID of 16 bytes size.
NSUUID *estimoteUUID = [[NSUUID alloc] initWithUUIDString:[Repository getiBeaconRegionUUID]];
_beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:estimoteUUID
identifier:#"A"];
// Launch app when display is turned on and inside region.
_beaconRegion.notifyEntryStateOnDisplay = YES;
// Create a location manager
_locationManager = [[CLLocationManager alloc] init];
// Set delegate
_locationManager.delegate = self;
if ([CLLocationManager isMonitoringAvailableForClass:[CLBeaconRegion class]])
{
[_locationManager requestAlwaysAuthorization];
[_locationManager startMonitoringForRegion:_beaconRegion];
// Get status update right away for UI
[_locationManager requestStateForRegion:_beaconRegion];
}
else
NSLog(#"This device does not support monitoring beacon regions");
There is the NSLocationAlwaysUsageDescription added to the app. plist.
There was never the dialog with the text from the key above.
In Settings => Privacy => Location Services for the app. was turned off after the first app. run.
The delegate method
- (void)locationManager:(CLLocationManager *)manager
didDetermineState:(CLRegionState)state
forRegion:(CLRegion *)region
is never called.
In iOS 7 the same app. worked without the authorization request.
Share your experience.
i have face same problem when i migrate to ios8 from ios7.and i have done following way with the apple doc with explanation of mine.
Check What apple says Here :
APPLE DOC
from iOS 8, NSLocationWhenInUseUsageDescription or a NSLocationAlwaysUsageDescription key value in Info.plist file is required.but also you need to request permission from the user before you registering for location updates, either by calling [_locationManager requestWhenInUseAuthorization] or [_locationManager requestAlwaysAuthorization] choose any of above as per you requirement.
please note this info it will gonna help through out ios 8.
After I added NSLocationAlwaysUsageDescription key-value pair into InfoPlist.strings it showed the dialog and started to work.
Spent few days trying to solve this but unable to find any solutions that works. I have checked all the post on stackoverflow and tried all their solutions and nothing seems to be working for. I have also tried the apple test project for CLLocation which works fine for me. I used bits and pieces from the apple test project
https://developer.apple.com/library/ios/samplecode/LocateMe/Listings/README_md.html
But my code is not working at all. The DidupdateToLocation never gets called.
Here is my code (in viewDidLoad)
_locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
// This is the most important property to set for the manager. It ultimately determines how the manager will
// attempt to acquire location and thus, the amount of power that will be consumed.
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
// Once configured, the location manager must be "started"
//
// for iOS 8, specific user level permission is required,
// "when-in-use" authorization grants access to the user's location
//
// important: be sure to include NSLocationWhenInUseUsageDescription along with its
// explanation string in your Info.plist or startUpdatingLocation will not work.
//
if ([self.locationManager respondsToSelector:#selector(requestWhenInUseAuthorization)]) {
[self.locationManager requestWhenInUseAuthorization];
}
[self.locationManager startUpdatingLocation];
[self performSelector:#selector(stopUpdatingLocationWithMessage:)
withObject:#"Timed Out"
afterDelay:30];
I have checked to make sure locationServicesEnabled is enabled.
I have added NSLoationWhenInUseUsageDescription property to the info.plist file. Is there any other property I need to add or enable any services??
I cannot for the love of god figure out what i have done wrong. Can some one please help me with this.
You have to call the startUpdatingLocation after you received the didChangeAuthorizationStatus callback on iOS8.
//iOS 8 API change
if([self.locationManager respondsToSelector:#selector(requestWhenInUseAuthorization)]){
[self.locationManager requestWhenInUseAuthorization];
}else{
[self.locationManager startUpdatingLocation];
}
implement this delegate method:
-(void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
{
switch (status) {
case kCLAuthorizationStatusNotDetermined:
case kCLAuthorizationStatusRestricted:
case kCLAuthorizationStatusDenied:
{
// do some error handling
}
break;
default:{
[self.locationManager startUpdatingLocation];
}
break;
}
}
First, don't forget, with IOS 8 you need to do [locationManager requestWhenInUseAuthorization] plus [locationManager requestAlwaysAuthorization];
_locationManager = [CLLocationManager new];
if(SYSTEM_IS_OS_8_OR_LATER) {
[_locationManager requestWhenInUseAuthorization];
[_locationManager requestAlwaysAuthorization];
}
_locationManager.delegate = self;
_locationManager.desiredAccuracy = kCLLocationAccuracyBest;
//and the problem with your code : don't forget to start
_locationManager startUpdatingLocation];
and in your didUpdateLocations
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{
_currentLocation = [locations objectAtIndex:0];
//do your stuff with the location
}
Silly me. I added the keywords to the wrong plist file. I have got it working now. Thanks for your help guys.
I just spend an entire morning on this [in honestly I am relative new OOC], anyway the problem..
didUpdateLocation compiles and is never called
didUpdateLocations compiles and does work!!
Not the answer in this case it would seem, but it is in the question, an easy mistake to make. Using IOS 8.1.3 & Xcode 6.1.1
Simply add three properties in Info.plist.
To get the current location, if it is not calling didUpdateToLocation method
NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription
privacy - location usage description of type String.
Hi I am implementing Location services in my app. First I have to know my Coordinates to get the distance between some places that I have in a list and the device. Then if I go into a place I can make a check in, so, I need to get coordinates again, and the problem is here. Second time I try to get coordinates, the method -(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations is not called.. and I can not get new Coordinates.
My manager is located in a NSObject sublcass with this code:
(id)init {
if ( self = [super init] ) {
if ([CLLocationManager locationServicesEnabled])
{
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
[locationManager startUpdatingLocation];
}
}
return self;
}
-(void) checkLongLatitudeAgain {
[locationManager startUpdatingLocation];
}
#pragma mark Delegates de CLLocationManager
//
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{
NSLog(#"LON%f", manager.location.coordinate.longitude);
NSLog(#"LAT:%f", manager.location.coordinate.latitude);
NSTimeInterval howRecentNewLocation = [newLocationeventDate timeIntervalSinceNow];
if (manager.location.horizontalAccuracy <= 100.0 && howRecentNewLocation < -0.0 && howRecentNewLocation > -20.0){
//Usar coordenada
[self.delegate getLocationForCheckIn:manager.location];
[self stopUpdatingLocation:#"Fins"];
}
}
// ---------------------------------------------------------------------------------------------------------------------
-(void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error{
//
if ([error code] != kCLErrorLocationUnknown) {
[self stopUpdatingLocation:NSLocalizedString(#"Error", #"Error")];
}
//
}
// ---------------------------------------------------------------------------------------------------------------------
- (void)stopUpdatingLocation:(NSString *)state {
//Detenemos la lectura del GPS
[locationManager stopUpdatingLocation];
locationManager.delegate = nil;
NSLog(#"Stop gps");
//
}
I call the class when the list of places is open, and also when inside a place the user press checkIn button. Both times I do it with this code:
WPLocationManager *location = [[WPLocationManager alloc]init];
[location checkLongLatitudeAgain];
You are creating a new manager every time:
WPLocationManager *location = [[WPLocationManager alloc]init];
[location checkLongLatitudeAgain];
That new manager is not assigned to any delegate.
You need to use the previous manager you have created and assigned to your delegate, something like:
[locationManager checkLongLatitudeAgain];
You can check the documentation at http://developer.apple.com - https://developer.apple.com/library/ios/documentation/userexperience/conceptual/LocationAwarenessPG/CoreLocation/CoreLocation.html
In particular you can check the Starting the Standard Location Service and Starting the Significant-Change Location Service sections. You have to use the startMonitoringSignificantLocationChanges or startUpdatingLocation method of CLLocationManager, cache your location somewhere and update it only when a new location is received, otherwise like it is stated in the documentation: "If a location update has already been delivered, you can also get the most recent location data directly from the CLLocationManager object without waiting for a new event to be delivered".
i dont know why you are initiating your location manager again again, also even if you some how manage to solve current problem but it's not proper way of dealing with location manage based applications.I had been in trouble previously when i was working on location based app. the best approach for location based app is singleton.
apple forum discussion
you can find
this
and this very helpful.
just an advice, :)
Thanks.
In iOS8 for me I had to call [locationManager stopUpdatingLocation]; before calling [locationManager startUpdatingLocation] to start getting updates second time and it works for me.
