leftCalloutAccessoryView image reference? - ios

Question

Hello i'm building a mapbased App when i'm tapping on the Accessory i perform a segue to a profile page which gives information about the pin location. Now i have a image in my LeftCalloutAccesoryView which a i want to show on the detail page. Now i'm curious if there is a method to get the image which a set on LeftCalloutAccesoryView. I add the images dynamically.
my accessorycontroltapped code:
-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view
calloutAccessoryControlTapped:(UIControl *)control
{
companytitle = view.annotation.title;
description = view.annotation.subtitle;
thumbprofileimage = view.image;
//thumbprofileimage = [(UIImageView *)view.leftCalloutAccessoryView setImage:pin.image];
//UIImageView *leftIconView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 30, 30)];
//leftIconView = [view.leftCalloutAccessoryView [[UIImageView alloc]];
//view.leftCalloutAccessoryView;
[self performSegueWithIdentifier:#"showPlattegrondDetails" sender:self];
}
my set pins code:
- (MKAnnotationView *)mapView:(MKMapView *)mpView viewForAnnotation:(id <MKAnnotation>)annotation {
static NSString *identifier = #"MyLocation";
if ([annotation isKindOfClass:[RouteAnnotation class]]) {
MKPinAnnotationView *annotationView =
(MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (annotationView == nil) {
annotationView = [[MKPinAnnotationView alloc]
initWithAnnotation:annotation
reuseIdentifier:identifier];
} else {
annotationView.annotation = annotation;
}
annotationView.enabled = YES;
annotationView.canShowCallout = YES;
leftIconView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 30, 30)];
[leftIconView setImage:pin.image];
annotationView.leftCalloutAccessoryView = leftIconView;
//annotationView.leftCalloutAccessoryView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 30, 30)];
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
annotationView.rightCalloutAccessoryView = rightButton;
return annotationView;
}
return nil;
}
Does someone have the solution of getting a reference to the image so i can send this image to the detail page?

Answer 1

You are already part way there with your mapView:annotationView:calloutAccessoryControlTapped: method.
Create a property to keep a reference to the image from the tapped callout:
#property (nonatomic, strong) UIImage *selectedCalloutImage;
And update the delegate method:
-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view
calloutAccessoryControlTapped:(UIControl *)control
{
companytitle = view.annotation.title;
description = view.annotation.subtitle;
thumbprofileimage = view.image;
//thumbprofileimage = [(UIImageView *)view.leftCalloutAccessoryView setImage:pin.image];
//UIImageView *leftIconView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 30, 30)];
//leftIconView = [view.leftCalloutAccessoryView [[UIImageView alloc]];
//view.leftCalloutAccessoryView;
// Keep a reference to the callout's image
self.selectedCalloutImage = [(UIImageView *)view.leftCalloutAccessoryView image];
[self performSegueWithIdentifier:#"showPlattegrondDetails" sender:self];
}
Then pass the image to the subsequent controller in the prepareForSegue:sender: method:
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:#"showPlattegrondDetails"])
{
DetailViewController *controller = segue.destinationViewController;
controller.image = self.selectedCalloutImage;
}
}
You can then display / use it however you like.
