单击 rightaccessoryview 后，我的程序将不会显示导航栏。它只显示视图，但不显示导航栏
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped: (UIControl *)control{
NSLog(@"Disclosure button pressed");
DetailView *tmpView = [[DetailView alloc]initWithNibName:@"DetailView" bundle:nil];
self.detailViewController = tmpView;
[self.navigationController pushViewController:self.detailViewController animated:YES];
//[self.view addSubview:detailViewController.view];
[tmpView release];
}
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped: (UIControl *)control{
NSLog(@"Disclosure button pressed");
DetailView *tmpView = [[DetailView alloc]initWithNibName:@"DetailView" bundle:nil];
self.detailViewController = tmpView;
[self.navigationController pushViewController:self.detailViewController animated:YES];
//[self.view addSubview:detailViewController.view];
[tmpView release];
}

您确定导航控制器存在于您单击地图注释的当前视图控制器中吗？确保 self.navigationController 不为零。
Are you sure the navigation controller exists in current view controller from where you click on the map annotation? Make sure self.navigationController is not nil.
