MKAnnotationView和MKPinAnnotationView的区别 代码示例

如果需要自定义大头针图片则创建MKAnnotationView

如果要使用苹果自带的大头针则创建MKPinAnnotationView  

代码：

#import "ViewController.h"

#import <MapKit/MapKit.h>

@interface ViewController () <MKMapViewDelegate>

{

   MKMapView *_mapView;

}

@end

@implementation ViewController

- (void)dealloc

{

    [_mapViewrelease];

    [superdealloc];

}

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

{

   self = [superinitWithNibName:nibNameOrNilbundle:nibBundleOrNil];

   if (self) {

        // Custom initialization

    }

    return self;

}

- (void)viewDidLoad

{

    [superviewDidLoad];

    _mapView = [[MKMapViewalloc]initWithFrame:CGRectMake(0,0,320,480)];

   _mapView.delegate =self;

    _mapView.mapType =MKMapTypeStandard;

    _mapView.showsUserLocation =YES;

    _mapView.userLocation.title =@"Me";

    _mapView.userLocation.subtitle =@"tips";

    _mapView.userTrackingMode =MKUserTrackingModeFollow;

    

   CLLocationCoordinate2D coordinate = {34.722148,113.74119};

    [self.viewaddSubview:_mapView];

    

    

    MKPointAnnotation *annotation = [[MKPointAnnotationalloc]init];

    annotation.coordinate = coordinate;

    annotation.title =@"自定标注";

    annotation.subtitle =@"is here";

    [_mapViewaddAnnotation:annotation];

    [annotationrelease];

    

    

}
