Question

这是BridgeAnnotation接口，它具有MKAnnotation的委托

@interface BridgeAnnotation : NSObject <MKAnnotation>
{

}
@property(nonatomic,retain) NSString *lat,*lon,*titlevalue,*subtitlevalue;
@property(nonatomic,assign) NSInteger  myindex;
@end

我在我的方法中将值设置为 myindex 变量，如下所示

  BridgeAnnotation *bridgeAnnotation = [[BridgeAnnotation alloc] init];
   [bridgeAnnotation setLat:[@"" stringByAppendingFormat:@"%f",theCoordinate.latitude]];
   [bridgeAnnotation setLon:[@"" stringByAppendingFormat:@"%f",theCoordinate.longitude]];
   [bridgeAnnotation setTitlevalue:[PMLObj ProductTitle]];
   [bridgeAnnotation setSubtitlevalue:[[PMLObj ProductPrice] stringByAppendingFormat:@"$"]];
    [bridgeAnnotation setMyindex:i];

   [self.mapView addAnnotation:bridgeAnnotation];

这是我的重复方法

- (MKAnnotationView *)mapView:(MKMapView *)theMapView viewForAnnotation:(id <MKAnnotation>)annotation
{
    if ([annotation isKindOfClass:[MKUserLocation class]])
        return nil;


        static NSString* BridgeAnnotationIdentifier = @"bridgeAnnotationIdentifier";
        MKPinAnnotationView* pinView = (MKPinAnnotationView *)
        [mapView dequeueReusableAnnotationViewWithIdentifier:BridgeAnnotationIdentifier];
        if (!pinView)
        {
            UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];


            NSLog(@"---%d",rightButton.tag);
            [rightButton addTarget:self
                            action:@selector(showDetails:)
                  forControlEvents:UIControlEventTouchUpInside];
            customPinView.rightCalloutAccessoryView = rightButton;

            return customPinView;
        }
        else
        {
            pinView.annotation = annotation;
        }
        return pinView;


}

在上面的方法中，我想访问BridgeAnnotation类的 myindex 。怎么可能？或者我必须使用其他方法??

任何人都可以帮助我吗？

如果要在点击上捕获注释，则应使用此委托

- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
{
  BridgeAnnotation *annotation = (BridgeAnnotation *)mapView.annotation;
  NSInteger *yourIndex = annotation.myindex;
}

请点击iphone中点击特定细节注释引脚的索引
