iPhone: CLLocation: Get current location

Published on June 27, 2013 by Kenny

Steps to basic geolocation:

1. Add CLLocation framework to Build Phases, Link Binary with Libraries

2. Set up instance variable in .h file:

Objective-C

1 2 3

CLLocationManager *locationManager;

3. Instantiate and set up location manager in the .m file:

Objective-C

1 2 3 4 5 6

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

4. Inside the button handler:

Objective-C

1 2 3

[locationManager startUpdatingLocation];

This tells the location manager to start updating.

5. This function gets called by the location manager. It is like a callback. The location manager will call this function every time the location is updated.

Objective-C

1 2 3 4 5 6 7

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

All this does in this case is dump the data to the debug window.
