Выноска Я нажимаю на карту и появляется ViewController2
Я не вижу вторую запись в Map и возьми меня к DetailViewController2,
Есть ли способ это исправить?

Решение
Этот метод:
- (void)mapView:(MKMapView *)mapView annotationView2:(MKAnnotationView *)view
calloutAccessoryControlTapped:(UIControl *)control
не будет вызван видом карты, потому что он не назван точно mapView:annotationView:calloutAccessoryControlTapped:,
Наименование метода annotationView2 не ассоциируется автоматически с вашей "второй" аннотацией. Методы делегата должны быть названы точно так, как определено протоколом (MKMapViewDelegate в этом случае).
Вы должны обработать все нажатия кнопки выноски в этом одном методе:
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view
calloutAccessoryControlTapped:(UIControl *)control
Там вы можете проверить класс аннотации и соответственно обработать (как вы уже делаете с BridgeAnnotation). Например:
if ([annotation1 isKindOfClass:[BridgeAnnotation class]])
{
//code for Bridge annotation...
}
else
if ([annotation1 isKindOfClass:[SFAnnotation class]])
{
//code for SF annotation...
}
else ...
