有多个引脚注释？ MapKit

Question

此刻我有1个针脚，当您点击该针脚时，它会显示信息。不过，我想要在不同位置使用1个以上的引脚。我将如何做到这一点？

这是我的代码。

Map.m

- (void)viewDidLoad 
{ 


    [super viewDidLoad]; 

    [mapview setMapType:MKMapTypeStandard]; 
    [mapview setZoomEnabled:YES]; 
    [mapview setScrollEnabled:YES]; 

    MKCoordinateRegion region = { {0.0, 0.0 }, {0.0, 0.0 } }; 
    region.center.latitude = 52.509078; 
    region.center.longitude = -1.884799; 
    region.span.longitudeDelta = 0.01f; 
    region.span.latitudeDelta = 0.01f; 
    [mapview setRegion:region animated:YES]; 

    NewClass *ann = [[NewClass alloc] init]; 
    ann.title = @"AVFC"; 
    ann.subtitle = @"Aston Villa Football Club"; 
    ann.coordinate = region.center; 
    [mapview addAnnotation:ann]; 

    // Do any additional setup after loading the view, typically from a nib. 
} 

NewClass.h

@interface NewClass : NSObject <MKAnnotation> { 


    CLLocationCoordinate2D coordinate; 
    NSString *title; 
    NSString *subtitle; 

    NSString *titleOne; 
    NSString *subtitleTwo; 

} 

@property (nonatomic, assign) CLLocationCoordinate2D coordinate; 
@property (nonatomic, copy) NSString *title; 
@property (nonatomic, copy) NSString *subtitle; 

@property (nonatomic, copy) NSString *titleOne; 
@property (nonatomic, copy) NSString *subtitleTwo; 
@end

创建您的注释（但很多你想要的）然后将它们添加到NSArray。您可以使用[mapview addAnnotations:annotationArray];

MKMapView Ref
