How to add an UIButton to placemark? ios objective c - ios

Question

How do I add a button to my placemarks and then get it to push onto a view controller?
- (void)viewDidLoad
{
[super viewDidLoad];
// Set "More" logo in navigation bar
self.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Navigation"]];
appDelegate=[[UIApplication sharedApplication] delegate];
// Set longatude and latitude to tyne and wear
CLLocationCoordinate2D center = CLLocationCoordinate2DMake(54.995184, -1.566699);
// Set span to cover area
MKCoordinateSpan span = MKCoordinateSpanMake(0.5, 0.5);
// Set region
MKCoordinateRegion regionToDisplay = MKCoordinateRegionMake(center, span);
[self.nearbyMapView setRegion: regionToDisplay];
for (int i = 0; i < [[appDelegate offersFeeds] count]; i++)
{
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
NSString *plotAddress = [[[appDelegate offersFeeds] objectAtIndex:i] valueForKey:#"addressline"];
NSString *plotTitle = [[[appDelegate offersFeeds] objectAtIndex:i] valueForKey:#"title"];
[geocoder geocodeAddressString:plotAddress completionHandler:^(NSArray *placemarks, NSError *error) {
if (placemarks && placemarks.count > 0)
{
CLPlacemark *topResult = [placemarks objectAtIndex:0];
MKPlacemark *placemark = [[MKPlacemark alloc]initWithPlacemark:topResult];
// Set title
MKPointAnnotation *pa = [[MKPointAnnotation alloc] init];
pa.coordinate = placemark.location.coordinate;
pa.title = plotTitle;
// Add placemark to map
[self.nearbyMapView addAnnotation:pa];
}
}];
}
}
I've had a look at MKAnotationView but struggling to understand how to get this working with CLPlacemark.

Add this before you add mapview to self.view
-(void)viewDidLoad
{
MKPointAnnotation *annotation = [[MKPointAnnotation alloc]init];
annotation.coordinate = yourCoordinate;
annotation.title = #"Title";
annotation.subtitle = #"SubTitle";
[mapView1 addAnnotation:annotation];
}
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
MKAnnotationView *pinView = nil;
static NSString *defaultPinID = #"identifier";
pinView = (MKAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
if ( pinView == nil )
{
pinView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID];
annotationView.enabled = YES;
pinView.canShowCallout = YES;
UIButton *btn = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
//Accessoryview for the annotation view in ios.
pinView.rightCalloutAccessoryView = btn;
}
else
{
pinView.annotation = annotation;
}
pinView.annotation = annotation;
return pinView;
}
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
//Put your button stuff here...
}
I hope it is useful to you
