Perni iOS MapKit personalizzati

Question

Come si visualizzano le immagini anziché i pin sulla mappa. Finora posso aggiungere solo i pin alla spina. Un codice di esempio del .m sarebbe estremamente utile dal momento che sono ancora nuovo alla programmazione iOS.

Answer 1

#pragma mark - 
#pragma mark MKMapView delegate 
- (MKAnnotationView *)mapView:(MKMapView *)mapview viewForAnnotation:(id <MKAnnotation>)annotation 
{ 
    if ([annotation isKindOfClass:[MKUserLocation class]]) 
     return nil; 
    static NSString* AnnotationIdentifier = @"AnnotationIdentifier"; 
    MKAnnotationView *annotationView = [mapView dequeueReusableAnnotationViewWithIdentifier:AnnotationIdentifier]; 
    if(annotationView) 
     return annotationView; 
    else 
    { 
     MKAnnotationView *annotationView = [[[MKAnnotationView alloc] initWithAnnotation:annotation 
                     reuseIdentifier:AnnotationIdentifier] autorelease]; 
     annotationView.canShowCallout = YES; 
     annotationView.image = [UIImage imageNamed:@"someImage.png"]; 
     UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; 
     [rightButton addTarget:self action:@selector(writeSomething:) forControlEvents:UIControlEventTouchUpInside]; 
     [rightButton setTitle:annotation.title forState:UIControlStateNormal]; 
     annotationView.rightCalloutAccessoryView = rightButton; 
     annotationView.canShowCallout = YES; 
     annotationView.draggable = YES; 
     return annotationView; 
    } 
    return nil; 
} 

EDIT:

potevo spiegare a tutti voi per il MKAnnotationView, ma penso che si trova la documentazione fornita da Apple per essere una spiegazione molto meglio che da qualsiasi altra fonte. Controlla la sezione panoramica nel link.

Answer 2

Vai organizzatore di Xcode e poi andare alla documentazione e di ricerca weathermap si vede ad esempio per la mappa con l'inclusione di immagini a annotazione.
