Question

How can I get the current location from user in iOS

User · Accepted Answer

The answer of RedBlueThing worked quite well for me. Here is some sample code of how I did it.

Header

#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>

@interface yourController : UIViewController <CLLocationManagerDelegate> {
    CLLocationManager *locationManager;
}

@end

MainFile

In the init method

locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[locationManager startUpdatingLocation];

Callback function

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
    NSLog(@"OldLocation %f %f", oldLocation.coordinate.latitude, oldLocation.coordinate.longitude);
    NSLog(@"NewLocation %f %f", newLocation.coordinate.latitude, newLocation.coordinate.longitude);
}

iOS 6

In iOS 6 the delegate function was deprecated. The new delegate is

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations

Therefore to get the new position use

[locations lastObject]

iOS 8

In iOS 8 the permission should be explicitly asked before starting to update location

locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
    [self.locationManager requestWhenInUseAuthorization];

[locationManager startUpdatingLocation];

You also have to add a string for the NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription keys to the app's Info.plist. Otherwise calls to startUpdatingLocation will be ignored and your delegate will not receive any callback.

And at the end when you are done reading location call stopUpdating location at suitable place.

[locationManager stopUpdatingLocation];

For Swift 5  here s a quick short class to get the location   class MyLocationManager  NSObject  CLLocationManagerDelegate       let manager  CLLocationManager      override init             manager   CLLocationManager           super init           manager delegate   self         manager distanceFilter   kCLDistanceFilterNone         manager desiredAccuracy   kCLLocationAccuracyBest         manager requestWhenInUseAuthorization           manager startUpdatingLocation              func locationManager   manager  CLLocationManager  didUpdateLocations locations   CLLocation                do something with locations

You can use this service I wrote to handle everything for you     This service will request the permissions and handle dealing with the CLLocationManager so you don t have to   Use like this    LocationService getCurrentLocationOnSuccess    latitude  longitude  - gt     in       Do something with Latitude and Longitude         onFailure     error  - gt     in          See what went wrong       print error

In Swift  for iOS 8    Info plist First things first  You need to add your descriptive string in the info plist file for the keys NSLocationWhenInUseUsageDescription or NSLocationAlwaysUsageDescription depending on what kind of service you are requesting Code import Foundation import CoreLocation  class LocationManager  NSObject  CLLocationManagerDelegate            let manager  CLLocationManager     var locationManagerClosures     userLocation  CLLocation  - gt                     override init             self manager   CLLocationManager           super init           self manager delegate   self                  This is the main method for getting the users location and will pass back the usersLocation when it is available     func getlocationForUser userLocationClosure    userLocation  CLLocation  - gt                          self locationManagerClosures append userLocationClosure                     First need to check if the apple device has location services availabel   i e  Some iTouch s don t have this enabled          if CLLocationManager locationServicesEnabled                   Then check whether the user has granted you permission to get his location             if CLLocationManager authorizationStatus       NotDetermined                     Request permission                   Note  you can also ask for  requestWhenInUseAuthorization                 manager requestWhenInUseAuthorization                 else if CLLocationManager authorizationStatus       Restricted    CLLocationManager authorizationStatus       Denied                         Sorry for you  You can huff and puff but you are not getting any location               else if CLLocationManager authorizationStatus       AuthorizedWhenInUse                      This will trigger the locationManager didUpdateLocation delegate method to get called when the next available location of the user is available                 manager startUpdatingLocation                                                     MARK  CLLocationManager Delegate methods           objc func locationManager manager  CLLocationManager  didChangeAuthorizationStatus status  CLAuthorizationStatus            if status     AuthorizedAlways    status     AuthorizedWhenInUse               manager startUpdatingLocation                            func locationManager manager  CLLocationManager  didUpdateToLocation newLocation  CLLocation  fromLocation oldLocation  CLLocation              Because multiple methods might have called getlocationForUser  method there might me multiple methods that need the users location            These userLocation closures will have been stored in the locationManagerClosures array so now that we have the users location we can pass the users location into all of them and then reset the array          let tempClosures   self locationManagerClosures         for closure in tempClosures               closure userLocation  newLocation                    self locationManagerClosures               Usage self locationManager   LocationManager   self locationManager getlocationForUser    userLocation  CLLocation  - gt     in             print userLocation

You use the CoreLocation framework to access location information about your user   You will need to instantiate a CLLocationManager object and call the asynchronous startUpdatingLocation message   You will get callbacks with the user s location via the CLLocationManagerDelegate that you supply

The Xcode Documentation has a wealth of knowledge and sample apps - check the Location Awareness Programming Guide   The LocateMe sample project illustrates the effects of modifying the CLLocationManager s different accuracy settings

In iOS 6  the  -  void locationManager  CLLocationManager   manager didUpdateToLocation  CLLocation   newLocation fromLocation  CLLocation   oldLocation   is deprecated   Use following code instead   -  void locationManager  CLLocationManager   manager      didUpdateLocations  NSArray   locations       CLLocation  location    locations lastObject       NSLog   lat f - lon f   location coordinate latitude  location coordinate longitude       For iOS 6 8  the above method is still necessary  but you have to handle authorization    locationManager    CLLocationManager new    locationManager delegate   self   locationManager distanceFilter   kCLDistanceFilterNone   locationManager desiredAccuracy   kCLLocationAccuracyBest   if     UIDevice currentDevice  systemVersion  floatValue   gt   8 0  amp  amp       CLLocationManager authorizationStatus     kCLAuthorizationStatusAuthorizedWhenInUse        CLLocationManager authorizationStatus     kCLAuthorizationStatusAuthorizedAlways                Will open an confirm dialog to get user s approval        locationManager requestWhenInUseAuthorization            locationManager requestAlwaysAuthorization     else         locationManager startUpdatingLocation     Will update location immediately      This is the delegate method which handle user s authorization    pragma mark - CLLocationManagerDelegate -  void locationManager  CLLocationManager  manager didChangeAuthorizationStatus  CLAuthorizationStatus status       switch  status        case kCLAuthorizationStatusNotDetermined            NSLog   User still thinking            break      case kCLAuthorizationStatusDenied            NSLog   User hates you          break      case kCLAuthorizationStatusAuthorizedWhenInUse      case kCLAuthorizationStatusAuthorizedAlways              locationManager startUpdatingLocation     Will update location immediately       break      default          break

iOS 11 x Swift 4 0 Info plist needs these two properties   lt key gt NSLocationAlwaysAndWhenInUseUsageDescription lt  key gt   lt string gt We re watching you lt  string gt   lt key gt NSLocationWhenInUseUsageDescription lt  key gt   lt string gt Watch Out lt  string gt    And this code     making sure of course your a CLLocationManagerDelegate  let locationManager   CLLocationManager       MARK location Manager delegate code   more  func locationManager   manager  CLLocationManager  didChangeAuthorization status  CLAuthorizationStatus        switch status       case  notDetermined          print  User still thinking       case  denied          print  User hates you       case  authorizedWhenInUse              locationManager stopUpdatingLocation       case  authorizedAlways              locationManager startUpdatingLocation       case  restricted          print  User dislikes you           And of course this code too which you can put in viewDidLoad     locationManager delegate   self locationManager requestAlwaysAuthorization   locationManager distanceFilter   kCLDistanceFilterNone locationManager desiredAccuracy   kCLLocationAccuracyBest locationManager requestLocation     And these two for the requestLocation to get you going  aka save you having to get out of your seat     func locationManager   manager  CLLocationManager  didFailWithError error  Error        print error     func locationManager   manager  CLLocationManager  didUpdateLocations locations   CLLocation         print locations
