如何在annotationView上设置按钮以在iPhone中执行操作？

Question

我想在 iphone 的 mapkit 的 commentView 中添加按钮，以便在单击该按钮时执行操作。单击该按钮后如何执行操作？我也无法使用以下代码在注释视图中添加按钮：

- (MKAnnotationView *)viewForAnnotation:(id <MKAnnotation>)annotation {
    MKPinAnnotationView *pinView = nil; 
    if(annotation != mapView.userLocation) 
    {
    static NSString *defaultPinID = @"com.invasivecode.pin";
        pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
        if ( pinView == nil )
            pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];

        pinView.pinColor = MKPinAnnotationColorRed; 
        pinView.canShowCallout = YES;
        pinView.animatesDrop = YES;

        UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
        [infoButton addTarget:self action:@selector(action:) forControlEvents:UIControlEventTouchUpInside];
        pinView.rightCalloutAccessoryView = infoButton;

    } 
    else {
        [mapView.userLocation setTitle:@"I am here"];
    }
    return pinView;
}

谁能告诉我如何将按钮添加到默认用户位置的蓝点注释视图中？提前致谢。

我曾经

- (void)mapView:(MKMapView *)eMapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control 

捕捉按钮按下的情况。

的按钮：

UIButton *detailButton = [UIButton buttonWithType: UIButtonTypeDetailDisclosure];
detailButton.frame = CGRectMake(0, 0, 44, 44);
detailButton.contentVerticalAlignment = UIControlContentVerticalAlignmentTop;
detailButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
annotationView.rightCalloutAccessoryView = detailButton;

我创建了这样

-(MKAnnotationView *)mapView:(MKMapView *)mv viewForAnnotation: (id<MKAnnotation>)annotation

只需看看我的代码示例：

- (MKAnnotationView *)mapView:(MKMapView *)mapView1 viewForAnnotation:(id <MKAnnotation>)annotation
{   
    if ([annotation isKindOfClass:[MKUserLocation class]])
        return nil;

    TagMark * tempMark = (TagMark *) annotation;

    MKPinAnnotationView *dropPin=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"venues"];

    dropPin.animatesDrop = YES;
    dropPin.canShowCallout = YES;

    UIButton *pinButton = [UIButton buttonWithType:UIButtonTypeCustom];
    pinButton.frame = CGRectMake(2, 2, 28, 29);
    [pinButton setImage:[UIImage imageNamed:@"ph.png"] forState:UIControlStateNormal];
    pinButton.tag = [[tempMark useID] intValue];
    [pinButton addTarget:self action:@selector(makeCall:) forControlEvents:UIControlEventTouchUpInside];

    dropPin.rightCalloutAccessoryView=pinButton; 

    return dropPin;
}

希望它能帮助您......

要在默认蓝点的annotationView中添加按钮，请使用委托方法并按以下方式添加按钮：

- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view {
if (!view.rightCalloutAccessoryView) {

    UIButton *detailButton = [UIButton buttonWithType: UIButtonTypeDetailDisclosure];
    view.rightCalloutAccessoryView = detailButton;

    detailButton.frame = CGRectMake(0, 0, 44, 44);
    detailButton.contentVerticalAlignment = UIControlContentVerticalAlignmentTop;
    detailButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;

 }
}
