How to Get Current Location from User 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];

SwiftUI: How to get the current location of user?

Yes, it's been deprecated in favour of using a property of the same name instead of a function, try it without the parentheses...

if manager.authorizationStatus == .authorizedWhenInUse {

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.)

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)]) {
       [locationManager requestWhenInUseAuthorization];
    }
    [locationManager startUpdatingLocation];
}

Not getting users current location in swift 4

The problem is your Info.plist. You need all three keys:

Sample Image

Fix that and the app will spring to life. I pasted your code into a project, set up the Info.plist as shown, and it worked fine.

You can actually omit "Always" starting in iOS 11, but you must have both "When In Use" and "Always and When In Use", even if you are planning to ask only for "Always".

The runtime was in fact telling you this all along in the Xcode console, but you apparently weren't looking at it. It says:

The app's Info.plist must contain both NSLocationAlwaysAndWhenInUseUsageDescription and NSLocationWhenInUseUsageDescription keys with string values explaining to the user how the app uses this data.

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 user current location in simulator in iphone sdk?

On iOS5 Simulator by default you it will show some location in USA. If you want to change that location, in iOS Simulator menu, go to Debug -> Location -> Custom Location.
There you can set the latitude and longitude and test the app accordingly. This works with mapkit and also with CLLocationManager.
