Question

我无法想象为什么它不起作用.. 我想要更改引脚颜色，并使用此方法提供的其他一些东西，但它只是不起作用。也许我使用这种方法错了？示例是最好的，谢谢。

    [mapView setMapType: MKMapTypeStandard];
[mapView setZoomEnabled:YES];
[mapView setScrollEnabled:YES];
for (NSDictionary *dict in self.klubiArray3) {
double latid = [[dict valueForKey:@"LatiS"] doubleValue];
double longid =[[dict valueForKey:@"LongiS"] doubleValue];
MKCoordinateRegion region = {{0.0, 0.0}, {0.0, 0.0}};


region.span.latitudeDelta = 0.005;
region.span.longitudeDelta = 0.005;
region.center.latitude = latid;
region.center.longitude = longid;

[mapView setRegion:region animated:YES];

NewClass *ann = [[NewClass alloc] init];
ann.title = [dict valueForKey:@"AnnotM"];
ann.subtitle = [dict valueForKey:@"Adress"];;
ann.coordinate = region.center;

[mapView addAnnotation:ann ];
}
 }
#pragma mark MKMapViewDelegate
- (MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation
{
       NSLog(@"Controll comes here");

if (annotation == mapView.userLocation) 
    return nil;

MKPinAnnotationView *pin = (MKPinAnnotationView *) [mapView dequeueReusableAnnotationViewWithIdentifier: @"asdf"];

if (pin == nil)
    pin = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier: @"asdf"] ;
else
    pin.annotation = annotation;
pin.userInteractionEnabled = YES;
UIButton *disclosureButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; 
[disclosureButton setFrame:CGRectMake(0, 0, 30, 30)];

pin.rightCalloutAccessoryView = disclosureButton;
pin.pinColor = MKPinAnnotationColorPurple;
//pin.animatesDrop = YES;
[pin setEnabled:YES];
[pin setCanShowCallout:YES];
return pin;

 }

发现，我忘了在Interface Builder中连接我的地图委托。
