How to Get Current Location Using Cllocationmanager in iOS

How can I get current location from user in iOS

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];

Get current location on iOS

From iOS 10 you need to add two keys to the info.plist as

NSLocationAlwaysUsageDescription key to your Info.plist file. (Xcode displays this key as "Privacy - Location Always Usage Description" in the Info.plist editor.)

And for iOS 11

Add the NSLocationWhenInUseUsageDescription key and the NSLocationAlwaysAndWhenInUseUsageDescription key to your Info.plist file. (Xcode displays these keys as "Privacy - Location When In Use Usage Description" and "Privacy - Location Always and When In Use Usage Description" in the Info.plist editor.)

Get User Current location using CLLocation in IOS

Check My code you can get address from current location

- (void)viewDidLoad {
CLGeocoder *ceo;

self.locationManager = [[CLLocationManager alloc]init];
self.locationManager.delegate = self;
[locationManager startUpdatingLocation];
}

-(void)viewDidAppear:(BOOL)animated{
ceo= [[CLGeocoder alloc]init];
[self.locationManager requestWhenInUseAuthorization];
if ([self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
    [self.locationManager requestWhenInUseAuthorization];
}
    CLLocationCoordinate2D coordinate;

coordinate.latitude=locationManager.location.coordinate.latitude;
coordinate.longitude=locationManager.location.coordinate.longitude;
//CLLocationCoordinate2D  ctrpoint;
//  ctrpoint.latitude = ;
//ctrpoint.longitude =f1;
//coordinate.latitude=23.6999;
//coordinate.longitude=75.000;
MKPointAnnotation *marker = [MKPointAnnotation new];
marker.coordinate = coordinate;
NSLog(@"%f",coordinate.latitude);
//[self.mapView addAnnotation:marker];

CLLocation *loc = [[CLLocation alloc]initWithLatitude:coordinate.latitude longitude:coordinate.longitude
                   ];
[ceo reverseGeocodeLocation:loc
          completionHandler:^(NSArray *placemarks, NSError *error) {
              CLPlacemark *placemark = [placemarks objectAtIndex:0];
              NSLog(@"placemark %@",placemark);
              //String to hold address
              NSString *locatedAt = [[placemark.addressDictionary valueForKey:@"FormattedAddressLines"] componentsJoinedByString:@", "];
              NSLog(@"addressDictionary %@", placemark.addressDictionary);

              NSLog(@"placemark %@",placemark.region);
              NSLog(@"placemark %@",placemark.country);  // Give Country Name
              NSLog(@"placemark %@",placemark.locality); // Extract the city name
              NSLog(@"location %@",placemark.name);
              NSLog(@"location %@",placemark.ocean);
              NSLog(@"location %@",placemark.postalCode);
              NSLog(@"location %@",placemark.subLocality);

              NSLog(@"location %@",placemark.location);
              //Print the location to console
              NSLog(@"I am currently at %@",locatedAt);

              _City.text=[placemark.addressDictionary objectForKey:@"City"];
              [locationManager stopUpdatingLocation];
          }

 ];
}

#pragma mark - CLLocationManagerDelegate

Please add this two method

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation

Hope This work

Thank you

How to get current longitude and latitude using CLLocationManager-Swift

IMHO, you are over complicating your code when the solution you are looking is pretty simple.

I have done it by using the following code:

First create an instance of CLLocationManager and Request Authorization

var locManager = CLLocationManager()
locManager.requestWhenInUseAuthorization()

then check if the user allowed authorization.

var currentLocation: CLLocation!

if 
   CLLocationManager.authorizationStatus() == .authorizedWhenInUse ||
   CLLocationManager.authorizationStatus() ==  .authorizedAlways
{         
    currentLocation = locManager.location        
}

to use it just do this

label1.text = "\(currentLocation.coordinate.longitude)"
label2.text = "\(currentLocation.coordinate.latitude)"

Your idea of setting them to the label.text is correct, however the only reason I can think of is that the user is not giving you permission and that is why your current Location data will be nil.

However you would need to debug and tell us that.
Also the CLLocationManagerDelegate is not necessary.

Hopefully this helps. Ask away if you have doubts.

How to get Current Location using SwiftUI, without ViewControllers?

You could create a StateObject of your LocationManager by implementing the ObservableObject protocol.

With the @Published attribute you can create a publisher object which notify the observers (your view, in this case) when something changes inside that object.

That's why in my LocationManager I added the @Published attribute to those var:

1. locationStatus: CLAuthorizationStatus? it contains the value received from didChangeAuthorization delegate method
2. lastLocation: CLLocation? it contains the last location calculated by the didUpdateLocations delegate method

LocationManager

import Foundation
import CoreLocation
import Combine

class LocationManager: NSObject, ObservableObject, CLLocationManagerDelegate {

    private let locationManager = CLLocationManager()
    @Published var locationStatus: CLAuthorizationStatus?
    @Published var lastLocation: CLLocation?

    override init() {
        super.init()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestWhenInUseAuthorization()
        locationManager.startUpdatingLocation()
    }

   
    
    var statusString: String {
        guard let status = locationStatus else {
            return "unknown"
        }
        
        switch status {
        case .notDetermined: return "notDetermined"
        case .authorizedWhenInUse: return "authorizedWhenInUse"
        case .authorizedAlways: return "authorizedAlways"
        case .restricted: return "restricted"
        case .denied: return "denied"
        default: return "unknown"
        }
    }

    func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        locationStatus = status
        print(#function, statusString)
    }
    
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        guard let location = locations.last else { return }
        lastLocation = location
        print(#function, location)
    }
}

View

In your view you need to create only an instance of LocationManager marked as @StateObject

import SwiftUI

struct MyView: View {
    
    @StateObject var locationManager = LocationManager()
    
    var userLatitude: String {
        return "\(locationManager.lastLocation?.coordinate.latitude ?? 0)"
    }
    
    var userLongitude: String {
        return "\(locationManager.lastLocation?.coordinate.longitude ?? 0)"
    }
    
    var body: some View {
        VStack {
            Text("location status: \(locationManager.statusString)")
            HStack {
                Text("latitude: \(userLatitude)")
                Text("longitude: \(userLongitude)")
            }
        }
    }
}

struct MyView_Previews: PreviewProvider {
    static var previews: some View {
        MyView()
    }
}

How to get current location in ios in simulator?

Create a GPX file by using following steps:

• Go in project--> Add new --> iOS -- > Resource and select GPX file

• Now you need to do small code in to GPX file as following:

---

<!--
        Provide one or more waypoints containing a latitude/longitude pair. If you provide one
        waypoint, Xcode will simulate that specific location. If you provide multiple waypoints,
        Xcode will simulate a route visitng each waypoint.
 -->
<wpt lat="37.331705" lon="-122.030237">  // here change lat long to your lat long
     <name>Cupertino</name> // here set name 

     <!--   
            Optionally provide a time element for each waypoint. Xcode will interpolate movement
            at a rate of speed based on the time elapsed between each waypoint. If you do not provide
            a time element, then Xcode will use a fixed rate of speed.

            Waypoints must be sorted by time in ascending order.
      -->
     <time>2014-09-24T14:55:37Z</time>
</wpt>

• Now go to edit schema

  

• And select run and do in Option menu select like following there is appear our GPX file select that and run and close:

That's it now you can get location of your added lat long in GPX file.

UPDATE

Following is a code for enable location:

• In info.plist you need set NSLocationWhenInUseUsageDescription and NSLocationWhenInUseUsageDescription about location services.

Now your .h class

#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
@interface ViewController : UIViewController<CLLocationManagerDelegate>
{

    __weak IBOutlet UILabel *lblLat;
    __weak IBOutlet UILabel *lblLong;
}
@property(strong,nonatomic) CLLocationManager *locationManager;
@end

.M class

- (void)viewDidLoad {
    [super viewDidLoad];

    self.locationManager = [[CLLocationManager alloc] init];
    [self.locationManager requestWhenInUseAuthorization];

    self.locationManager.delegate = self;
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;

    [self.locationManager startUpdatingLocation];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
    NSLog(@"didFailWithError: %@", error);
    UIAlertView *errorAlert = [[UIAlertView alloc]
                               initWithTitle:@"Error" message:@"Failed to Get Your Location" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [errorAlert show];
}

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
    NSLog(@"didUpdateToLocation: %@", newLocation);
    CLLocation *currentLocation = newLocation;

    if (currentLocation != nil) {
        lblLat.text = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.latitude];
        lblLong.text = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.longitude];
    }
}

How to get current location IOS device

I give you the solution step by step

STEP 1:

First we should get the
Google Map SDK

Drag the following bundles into your project (when prompted, select Copy items if needed):

Subspecs/Base/Frameworks/GoogleMapsBase.framework
Subspecs/Maps/Frameworks/GoogleMaps.framework
Subspecs/Maps/Frameworks/GoogleMapsCore.framework

Right-click GoogleMaps.framework in your project, and select Show In Finder.

Drag the GoogleMaps.bundle from the Resources folder into your project. When prompted, ensure Copy items into destination group's folder is not selected.

Select your project from the Project Navigator, and choose your application's target.

Open the Build Phases tab, and within Link Binary with Libraries, add the following frameworks:

GoogleMapsBase.framework
GoogleMaps.framework
GoogleMapsCore.framework
GoogleMapsM4B.framework (Premium Plan customers only)
Accelerate.framework
CoreData.framework
CoreGraphics.framework
CoreLocation.framework
CoreText.framework
GLKit.framework
ImageIO.framework
libc++.tbd
libz.tbd
OpenGLES.framework
QuartzCore.framework
SystemConfiguration.framework
UIKit.framework

STEP 2:

Get the API key

STEP 3:

Add the below things in your Plist    

  App Transport Security Settings   Dictionary 
  Allow Arbitrary Loads             Boolean          YES

  <key>NSLocationWhenInUseUsageDescription</key>
  <string>RehabTask requires location services to work</string>

  <key>NSLocationAlwaysUsageDescription</key>
  <string>RehabTask requires location services to work</string>        

            OR

   Privacy - Location When In Use Usage Description   string    RehabTask requires location services to work
   Privacy - Location Always Usage Description        string    RehabTask requires location services to work

Also you need to add

  <key>LSApplicationQueriesSchemes</key>
  <array>
     <string>googlechromes</string>
     <string>comgooglemaps</string>
  </array>

STEP 4: In appDelegate add below code

AppDelegate.m

@import GoogleMaps;
#import "AppDelegate.h"

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
   [GMSServices provideAPIKey:@"AIzaSyCrCEb7qVkURIjq6jsfkPkwgN62sfj6Ff0"];
   return YES;
}

STEP 5:

ViewController.h

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

@interface ViewController : UIViewController<CLLocationManagerDelegate,GMSMapViewDelegate>{
    CLLocation *currentLocation;
}

@property (strong, nonatomic) IBOutlet UIView *viewDirection;
@property (nonatomic, strong) CLLocationManager *locationManager;
@property (nonatomic, strong) GMSMapView *mapView;
@end

ViewController.m

#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
@synthesize viewDirection,locationManager,
@synthesize mapView;

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
    locationManager = [[CLLocationManager alloc]init];
    locationManager.delegate = self;
    locationManager.distanceFilter = 10;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    if([CLLocationManager locationServicesEnabled] == NO){
        NSLog(@"Your location service is not enabled, So go to Settings > Location Services");
    }
    else{
        NSLog(@"Your location service is enabled");
    }
    if ([locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
