Pergunta

eu tenho um MKMapView Implementado com essas linhas de código -fonte (minha localização é uma bala azul, a outra é pinos roxos):

- (MKAnnotationView *)mapView:(MKMapView *)mapViewLocal viewForAnnotation:(id <MKAnnotation>)annotation {
    if (annotation == mapViewLocal.userLocation) {
        mapViewLocal.userLocation.title = @"Test";
        [mapViewLocal setRegion:MKCoordinateRegionMakeWithDistance(mapViewLocal.userLocation.coordinate, 1000, 1000) animated:YES];
        return nil;
    }

    MKPinAnnotationView *pinView = (MKPinAnnotationView*)[mapViewLocal dequeueReusableAnnotationViewWithIdentifier:@"Pin"];
        if(pinView == nil) {
            pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"Pin"] autorelease];
            pinView.pinColor = MKPinAnnotationColorPurple;
            pinView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
            pinView.animatesDrop = NO;
            pinView.canShowCallout = YES;
        } else {
            pinView.annotation = annotation;
        }
        return pinView;
    }

Os pinos roxos têm um botão de divulgação de detalhes, mas minha anotação não possui um. Como posso definir esse botão?

E esse é o método em que eu posso fazer algo um botão é pressionado:

-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control

Como eu poderia diferenciar entre minha localização e todos os outros, porque preciso de um manuseio diferente. Existe outro delegado ou eu tenho que fazer algum tipo de cláusula se?

Foi útil?

Solução

na tua didUpdateToLocation Escreva algo como

AddressAnnotation   *myAnnotation = [[AddressAnnotation alloc] initWithCoordinate:currentLocation];
                myAnnotation.title = @"You are here";
                [self.mapView addAnnotation:myAnnotation];

E depois

Algo como

- (MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation
{
           // try to dequeue an existing pin view first
        static NSString* annotationIdentifier = @"annotationIdentifier";

        NSString *titlestr = annotation.title;

        MKPinAnnotationView* pinView = (MKPinAnnotationView *)
        [mapView dequeueReusableAnnotationViewWithIdentifier:annotationIdentifier];
    MKPinAnnotationView* customPinView = [[[MKPinAnnotationView alloc]
                                           initWithAnnotation:annotation reuseIdentifier:nil] autorelease];
        if (!pinView)
        {
            // if an existing pin view was not available, create one
           // MKPinAnnotationView* customPinView = [[[MKPinAnnotationView alloc]
                                                   //initWithAnnotation:annotation reuseIdentifier:annotationIdentifier] autorelease];
            if([titlestr isEqualToString:@"You are here"])
            {
                customPinView.pinColor = MKPinAnnotationColorGreen;
                NSLog(@"customPinView.pinColor = MKPinAnnotationColorGreen;");
            }
            else{
                customPinView.pinColor = MKPinAnnotationColorPurple;
                customPinView.selected = TRUE;
                NSLog(@"customPinView.pinColor = MKPinAnnotationColorPurple;");
                UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
                [rightButton addTarget:self
                                action:@selector(ShowStoreDetail:)
                      forControlEvents:UIControlEventTouchUpInside];
                customPinView.rightCalloutAccessoryView = rightButton;
            }
            customPinView.animatesDrop = YES;
            customPinView.canShowCallout = YES;

            return customPinView;
        }
        else
        {
            pinView.annotation = annotation;



            if([titlestr isEqualToString:@"You are here"])
            {
                customPinView.pinColor = MKPinAnnotationColorPurple;
                NSLog(@"customPinView.pinColor = MKPinAnnotationColorGreen;");
            }
            else{
                customPinView.pinColor = MKPinAnnotationColorPurple;
                customPinView.selected = TRUE;
                NSLog(@"customPinView.pinColor = MKPinAnnotationColorPurple;");
                UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
                [rightButton addTarget:self
                                action:@selector(ShowStoreDetail:)
                      forControlEvents:UIControlEventTouchUpInside];
                customPinView.rightCalloutAccessoryView = rightButton;
            }


        }
        return pinView;

    return nil;
}
