Push another view when click on rightCalloutAccessoryView - objective-c

Question

When I click on the right callout on the PIN, i want to move to a new view controller named DetailsThemes, however, when i do so:
-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
[self.navigationController pushViewController:self.detailsThemes animated:YES];
}
I got this error:
Property detailsThemes not found on object of type 'ViewController *';
did you mean to access ivar 'detailsThemes'?
Although, detailsThemes is an instance of DetailsThemes which is a UIViewController class, also, in my class I did invoke the DetailsThemes class with #class DetailsThemes; on the top of the file like this:
#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>
#class DetailsThemes;
#interface ViewController : UIViewController<MKMapViewDelegate>
{
DetailsThemes * detailsThemes;
}
#property (weak, nonatomic) IBOutlet MKMapView *mapView;
#end
EDIT:
-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
NSLog(#"calloutAccessoryControlTapped: %#",view.annotation);
[self.navigationController pushViewController:self.detailsThemes animated:YES];
}
- (MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation {
static NSString *identifier = #"ManageAnnotations";
MKPinAnnotationView *annotationView = (MKPinAnnotationView *) [map dequeueReusableAnnotationViewWithIdentifier:identifier];
if (annotationView == nil) {
annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
} else {
annotationView.annotation = annotation;
}
annotationView.enabled = YES;
[annotationView setAnimatesDrop:YES];
annotationView.canShowCallout = YES;
//annotationView.pinColor = ((ManageAnnotations *)annotation).pinColor;
annotationView.rightCalloutAccessoryView=[UIButton buttonWithType:UIButtonTypeInfoLight];
return annotationView;
}

In your ViewDidLoad method you have to allocate first your DetailsThemes and then use it in your call out. if you still not success then please post code of your callOutAccessoryView
