How to get current locaton's Lat & Long in IOS

You can use CoreLocation to get the longitude and latitude.

Include framework:

Click your project in navigator.

Click the plus button under "link binary with libraries"

Add Corelocation to your project.

Import the header file:

#import <CoreLocation/CoreLocation.h>

Declare CLLocationManager:

CLLocationManager *locationManager;

initialize locationManager:

- (void)viewDidLoad
{
    locationManager = [[CLLocationManager alloc] init];
    locationManager.distanceFilter = kCLDistanceFilterNone; 
    locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters;
    [locationManager startUpdatingLocation];
}

Then, use

float latitude = locationManager.location.coordinate.latitude;
float longitude = locationManager.location.coordinate.longitude;

You need to do two extra things to get location working:

1. Add a key to your Info.plist
2. Request authorization from the location manager asking it to start.

Any one or both of below keys needs to be added in Info.plist file.

1. NSLocationWhenInUseUsageDescription
2. NSLocationAlwaysUsageDescription

These are of String type and value can be any message description or empty.

Now you need to request authorisation for corresponding location method. Use any one of below calls :

1. [self.locationManager requestWhenInUseAuthorization]
2. [self.locationManager requestAlwaysAuthorization]
