マップに完全に表示される注釈を作成しましたが、画像を表示するために leftCalloutAccessoryView を実装する方法がわかりません。

MapViewAnnotation.h

#import <Foundation/Foundation.h>

@interface MapViewAnnotation : NSObject <MKAnnotation>

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

@end

MapViewAnnotation.m

#import "MapViewAnnotation.h"

@implementation MapViewAnnotation
@synthesize coordinate, title, subtitle;

@end

GroundsViewController.h

#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>


@interface GroundsViewController : UIViewController <MKMapViewDelegate>
{
    MKMapView *mapView;
}

@property (strong, nonatomic) IBOutlet UISegmentedControl *segment;
