ios - 将披露按钮添加到 MKPointAnnotation

Question

为了在 Storyboard iOS 项目中创建 map 注释，我使用了:

    CLLocationCoordinate2D annotationCoord3;

        annotationCoord3.latitude = 34.233129;
        annotationCoord3.longitude = -118.998644;

        MKPointAnnotation *annotationPoint3 = [[MKPointAnnotation alloc] init];
        annotationPoint3.coordinate = annotationCoord3;
        annotationPoint3.title = @"Another Spot";
        annotationPoint3.subtitle = @"More than a Fluke";
        [_mapView addAnnotation:annotationPoint3];

效果很好，但我想添加一个披露按钮，这样我就可以将序列推送到新的 View Controller 并显示图像。这可能吗？

提前致谢，

将您的类声明为 MKMapViewDelegate。然后，添加

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


    MKAnnotationView *annotationView = [mapView dequeueReusableAnnotationViewWithIdentifier:@"String"];
    if(!annotationView) {   
        annotationView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"String"];
        annotationView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
    }

    annotationView.enabled = YES;
    annotationView.canShowCallout = YES;

    return annotationView;
}

然后你添加:

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control {
    // Go to edit view
    ViewController *detailViewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
   [self.navigationController pushViewController:detailViewController animated:YES];

}

... ViewController 可以是您定义的任何内容(我使用 nib 文件...)
