Question

我想在xcode中点击mapview注释上的右键后显示详细视图，但我无法显示视图，我的代码：

- (void)showDetails:(id)sender
{
  [self.navigationController setToolbarHidden:YES animated:NO];

[self.navigationController pushViewController:self.detailViewController animated:YES];

}



- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
static NSString* BridgeAnnotationIdentifier = @"bridgeAnnotationIdentifier";

MKPinAnnotationView* customPinView = [[[MKPinAnnotationView alloc]
                                       initWithAnnotation:annotation reuseIdentifier:BridgeAnnotationIdentifier] autorelease];
customPinView.pinColor = MKPinAnnotationColorPurple;
customPinView.animatesDrop = YES;
customPinView.canShowCallout = YES;

UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
NSLog(@"%@",rightButton);
[rightButton addTarget:self
                action:@selector(showDetails:)
      forControlEvents:UIControlEventTouchUpInside];
customPinView.rightCalloutAccessoryView = rightButton;
return customPinView;//[kml viewForAnnotation:annotation];
}

调用showDetails方法但不能将detailViewController推送到顶部，

[self.navigationController pushViewController:self.detailViewController animated:YES];

此代码应将详细信息视图推送到顶部并显示detailView但不满意，

任何帮助都会非常感激，我想做的是当有人在mapview上点击注释的右键时，我想要显示一个详细视图，提前感谢你..

Answer 1

不需要目标/操作，在点击标注附件视图时会调用一个委托方法：mapView:annotationView:calloutAccessoryControlTapped:

Answer 2

谢谢你的帮助，我可以通过改变我的showDetails方法来打开detailViewController

- (void)showDetails:(id)sender
    {
      detailViewController *dvController = [[detailViewController alloc] initWithNibName:nil bundle:nil];
      [self presentModalViewController:dvController animated:YES];
      [dvController release];
      dvController = nil;
    }

尝试在xcode中的mapview注释上点击右键时推送详细视图
