#P6 Location and Map Application

Description

Develop Map application to display map location based on the specified location.

Screens

Project Creation

• Create new Xcode project and select “Single View project” template under iOS->Application

• Add CoreLocation and MapKit Frameworks, which are necessary to handle Core location and Map functionalities.

• Open ViewController.xib file and add MapView UI object from the object library. Connect mapView object with the File Owner. The mapView is defined in the ViewController.h interface

Do method implementation

1) ViewController.h

#import <UIKit/UIKit.h>

#import <CoreLocation/CoreLocation.h>

#import <MapKit/MapKit.h>

@interface ViewController : UIViewController <CLLocationManagerDelegate> {

    CLLocationManager *locationManager;

    IBOutlet MKMapView *mapView;

}

@property (nonatomic, retain) CLLocationManager *locationManager;

@property (nonatomic, retain) IBOutlet MKMapView *mapView;

@end

2) ViewController.m

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

@synthesize locationManager, mapView;

- (void)viewDidLoad

{

    [super viewDidLoad];

      locationManager = [[CLLocationManager alloc] init];

   

    if ([CLLocationManager locationServicesEnabled]) {

        locationManager.delegate = self;

        [locationManager startUpdatingLocation];

    } else {

        NSLog(@"Location Service exception...");

    }

}

- (void)locationManager:(CLLocationManager *)manager

    didUpdateToLocation:(CLLocation *)newLocation

           fromLocation:(CLLocation *)oldLocation {

   

    NSLog(@"latitude=%f, longitude=%f",

          [newLocation coordinate].latitude,

          [newLocation coordinate].longitude);

   

    MKCoordinateRegion region = MKCoordinateRegionMake([newLocation coordinate], MKCoordinateSpanMake(.2, .2));

    [mapView setCenterCoordinate:[newLocation coordinate]];

    [mapView setRegion:region];

}

- (void)locationManager:(CLLocationManager *)manager

       didFailWithError:(NSError *)error{

    NSLog(@"Error");

}

- (void)didReceiveMemoryWarning

{

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

}

- (void)dealloc {

    [locationManager release];

    [super dealloc];

}

@end

Testing

• Send test location details using Simulator
