MKLocalSearch を追加したところ、ピンが正しく表示されています。唯一の問題は、名前だけが必要な場合、ピンのタイトルに名前と住所の両方が含まれていることです。どうすればこれを変更できますか。これが私が使用しているコードです-
- (void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated
{
MKLocalSearchRequest *request = [[MKLocalSearchRequest alloc] init];
request.naturalLanguageQuery = @"School";
request.region = mapView.region;
MKLocalSearch *localSearch = [[MKLocalSearch alloc] initWithRequest:request];
[localSearch startWithCompletionHandler:^(MKLocalSearchResponse *response, NSError *error) {
NSMutableArray *annotations = [NSMutableArray array];
[response.mapItems enumerateObjectsUsingBlock:^(MKMapItem *item, NSUInteger idx, BOOL *stop) {
// if we already have an annotation for this MKMapItem,
// just return because you don't have to add it again
for (id<MKAnnotation>annotation in mapView.annotations)
{
if (annotation.coordinate.latitude == item.placemark.coordinate.latitude &&
annotation.coordinate.longitude == item.placemark.coordinate.longitude)
{
return;
}
}
// otherwise, add it to our list of new annotations
// ideally, I'd suggest a custom annotation or MKPinAnnotation, but I want to keep this example simple
[annotations addObject:item.placemark];
}];
[mapView addAnnotations:annotations];
}];
}
