[IOS地图开发系类]3、地图视图MKMapview

  在第二部的基础上，我们给视图添加给MKMapview，具体代码如下：

@interface ViewController ()<CLLocationManagerDelegate>
@property (nonatomic,retain)MKMapView* mapView;
@property (nonatomic,retain)CLLocationManager* locationManager;
@property (nonatomic,retain)CLLocation* location;
@property (nonatomic, retain) CLGeocoder *myGeocoder;

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
	// Do any additional setup after loading the view, typically from a nib.
    MKMapView* map = [[MKMapView alloc] initWithFrame:self.view.frame];
    map.mapType = MKMapTypeStandard;
    map.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
    [self.view addSubview:map];
    [map release];
    self.mapView = map;    
    
    
    
    UIButton *addBt = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    addBt.frame = CGRectMake(0, 00, 320, 50);
    [addBt setTitle:@"locationMe" forState:UIControlStateNormal];
   
    [ addBt addTarget:self action:@selector(handleLocationMe:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview: addBt];
    
    
    
    if ([CLLocationManager locationServicesEnabled]){
        self.locationManager = [[CLLocationManager alloc] init];
        self.locationManager.delegate = self;
        self.locationManager.purpose =
        @"To provide functionality based on user's current location.";
        [self.locationManager startUpdatingLocation];
    } else {
        /* Location services are not enabled.
         Take appropriate action: for instance, prompt the user to enable location services */
        NSLog(@"Location services are not enabled");
    }
    
    self.myGeocoder = [[CLGeocoder alloc] init];
    
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

-(IBAction)handleLocationMe:(id)sender
{    
    [self.myGeocoder
     reverseGeocodeLocation:self.location completionHandler:^(NSArray *placemarks, NSError *error) {
         if (error == nil &&[placemarks count] > 0){
        CLPlacemark *placemark = [placemarks objectAtIndex:0];
        /* We received the results */
        NSLog(@"Country = %@", placemark.country);
        NSLog(@"Postal Code = %@", placemark.postalCode);
        NSLog(@"Locality = %@", placemark.locality);
             NSLog(@"dic = %@", placemark.addressDictionary );
        NSLog(@"dic FormattedAddressLines= %@", [placemark.addressDictionary objectForKey:@"FormattedAddressLines"]);
             NSLog(@"dic Name = %@", [placemark.addressDictionary objectForKey:@"Name"]);
             NSLog(@"dic State = %@", [placemark.addressDictionary objectForKey:@"State"]);
             NSLog(@"dic Street = %@", [placemark.addressDictionary objectForKey:@"Street"]);
             NSLog(@"dic SubLocality= %@", [placemark.addressDictionary objectForKey:@"SubLocality"]);
             NSLog(@"dic SubThoroughfare= %@", [placemark.addressDictionary objectForKey:@"SubThoroughfare"]);
             NSLog(@"dic Thoroughfare = %@", [placemark.addressDictionary objectForKey:@"Thoroughfare"]);

        
    }
     else if (error == nil &&
              [placemarks count] == 0){
         NSLog(@"No results were returned.");
     }
     else if (error != nil){
         NSLog(@"An error occurred = %@", error);
     }
     }];
}

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
    /* We received the new location */
    NSLog(@"Latitude = %f", newLocation.coordinate.latitude);
    NSLog(@"Longitude = %f", newLocation.coordinate.longitude);
    self.location = newLocation;
    
    
}
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error{
    /* Failed to receive user's location */
}


- (void)dealloc
{
    self.mapView = nil;
    self.location = nil;
    self.locationManager = nil;
    self.myGeocoder = nil;
    [super dealloc];
}

@end

运行后，结果如下：
