MapView programe in iPhone

1. Create a new project (ViewBased application )

2. Import the MapKit in header file…

#import <MapKit/MapKit.h>

also add the MapKit.framework under resources folder from the existing frameworks.

3. In the same viewController’s header file call the <MKMapViewDelegate> and define the MKMapView *myMapView; synthesize and release the myMapView object into implementation file.

4. In a viewcontroller.xib file ..add the map view on UIView and connect it with corresponding object in file owner. Further see the code given below….

Header

#import <UIKit/UIKit.h>

#import <MapKit/MapKit.h>

@interface myMapViewController : UIViewController <MKMapViewDelegate> {

IBOutlet MKMapView* myMapView;

}

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

-(void)displayMYMap;

@end

Implementation

#import “myMapViewController.h”

@implementation myMapViewController

@synthesize myMapView;

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.

– (void)viewDidLoad {

[super viewDidLoad];

myMapView = [[MKMapView alloc] initWithFrame:self.view.bounds];

myMapView.delegate=self;

[self.view addSubview:myMapView];

[NSThread detachNewThreadSelector:@selector(displayMYMap) toTarget:self withObject:nil];

}

-(void)displayMYMap

{

MKCoordinateRegion region;

MKCoordinateSpan span;

span.latitudeDelta=0.2;

span.longitudeDelta=0.2;

CLLocationCoordinate2D location;

location.latitude = 22.569722 ;

location.longitude = 88.369722;

region.span=span;

region.center=location;

[myMapView setRegion:region animated:TRUE];

[myMapView regionThatFits:region];

}

– (void)didReceiveMemoryWarning {

// Releases the view if it doesn’t have a superview.

[super didReceiveMemoryWarning];

// Release any cached data, images, etc that aren’t in use.

}

– (void)dealloc {

[super dealloc];

[myMapView release];

}

@end
