En tus

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation

agregue lo siguiente debajo de su MKAnnottionView

Answer 2

@interface Annotation : NSObject <MKAnnotation>
@property(nonatomic, assign) CLLocationCoordinate2D coordinate;
@property(nonatomic, copy) NSString *title;
@property(nonatomic, copy) NSString *subtitle;

Tuve que cambiar el título de asignar a copiar. :PAG
