如何使用mapKit框架自定义图标？

我正在使用MapKit框架来加载我的应用程序的谷歌地图，我放置在地图4“模拟”像这样的地方：

- (void)viewDidLoad { [super viewDidLoad]; mapView.delegate = self; mapView.showsUserLocation = YES; MKUserLocation *userLocation = mapView.userLocation; MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance (userLocation.location.coordinate,500,500); [mapView setRegion:region animated:NO]; //Simulated annotations on the map CLLocationCoordinate2D poi1Coord , poi2Coord , poi3Coord , poi4Coord; //poi1 coordinates poi1Coord.latitude = 37.78754; poi1Coord.longitude = -122.40718; //poi2 coordinates poi2Coord.latitude = 37.78615; poi2Coord.longitude = -122.41040; //poi3 coordinates poi3Coord.latitude = 37.78472; poi3Coord.longitude = -122.40516; //poi4 coordinates poi4Coord.latitude = 37.78866; poi4Coord.longitude = -122.40623; MKPointAnnotation *poi1 = [[MKPointAnnotation alloc] init]; MKPointAnnotation *poi2 = [[MKPointAnnotation alloc] init]; MKPointAnnotation *poi3 = [[MKPointAnnotation alloc] init]; MKPointAnnotation *poi4 = [[MKPointAnnotation alloc] init]; poi1.coordinate = poi1Coord; poi2.coordinate = poi2Coord; poi3.coordinate = poi3Coord; poi4.coordinate = poi4Coord; poi1.title = @"McDonald's"; poi1.subtitle = @"Best burgers in town"; poi2.title = @"Apple store"; poi2.subtitle = @"Iphone on sales.."; poi3.title = @"Microsoft"; poi3.subtitle = @"Microsoft's headquarters"; poi4.title = @"Post office"; poi4.subtitle = @"You got mail!"; [mapView addAnnotation:poi1]; [mapView addAnnotation:poi2]; [mapView addAnnotation:poi3]; [mapView addAnnotation:poi4]; 

}

代码非常简单。 我想要做的是，而不是使用我的谷歌地图上的典型的红色别针，使用我自己的图像来显示不同的地方。 有没有一个简单/直接的方法来做到这一点，因为我从我已经find的样本中感到困惑。

您可以使用以下代码更改注释图像，

 - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation { if ([[annotation title] isEqualToString:@"Current Location"]) { return nil; } MKAnnotationView *annView = [[MKAnnotationView alloc ] initWithAnnotation:annotation reuseIdentifier:@"currentloc"]; if ([[annotation title] isEqualToString:@"McDonald's"]) annView.image = [ UIImage imageNamed:@"mcdonalds.png" ]; else if ([[annotation title] isEqualToString:@"Apple store"]) annView.image = [ UIImage imageNamed:@"applestore.png" ]; else annView.image = [ UIImage imageNamed:@"marker.png" ]; UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; [infoButton addTarget:self action:@selector(showDetailsView) forControlEvents:UIControlEventTouchUpInside]; annView.rightCalloutAccessoryView = infoButton; annView.canShowCallout = YES; return annView; } 

其中“marker.png”是你的图片文件。
