一般的な吹き出しアクセサリを注釈領域に追加しようとしていますが、何らかの理由で表示されません。コードは次のとおりです。
- (void) setupMap:(PFObject*) venue {
...
OTNVenueAnnotation *annotation = [[OTNVenueAnnotation alloc] init];
annotation.coordinate = CLLocationCoordinate2DMake(location.latitude, location.longitude);
annotation.title = [[venue objectForKey:@"name"] uppercaseString];
annotation.venue = venue;
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
MKPinAnnotationView *customPinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"identifier"];
customPinView.leftCalloutAccessoryView = rightButton;
[self.mapView addAnnotation: annotation];
}
