마커 이벤트 및 동작
컬렉션을 사용해 정리하기
내 환경설정을 기준으로 콘텐츠를 저장하고 분류하세요.
특정 고급 마커 속성이 설정되면 탭, 동작과 같은 마커 이벤트를 모니터링할 수 있습니다.
마커를 탭하면 마커 제목이나 스니펫과 같은 추가 정보를 볼 수 있습니다. 길게 누르기 동작을 사용하여 드래그 가능한 마커를 이동할 수도 있습니다.
마커 이벤트에 응답
뷰에 GMSMapViewDelegate
프로토콜을 추가하고 해당 콜백을 구현하여 마커 이벤트에 응답할 수 있습니다. 이 예시에서는 선택한 마커의 title
및 snippet
을 식별합니다.
Swift
// MARK: GMSMapViewDelegate
func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {
if let title = marker.title {
if let snippet = marker.snippet {
print("marker title: \(title): snippet: \(snippet)")
}
}
return true
}
Objective-C
// MARK: GMSMapViewDelegate
- (BOOL)mapView:(GMSMapView *)mapView didTapMarker:(GMSMarker *)marker {
if (marker.title && marker.snippet) {
NSLog(@"marker with title:%@ snippet: %@", marker.title, marker.snippet)
}
return YES;
}
지도 확대/축소 수준별로 마커 표시 여부 관리
GMSMarker
의 표시 여부를 관리하려면 GMSMapViewDelegate
프로토콜을 구현하고 GMSMarker.map
을 설정하는 조건을 추가합니다.
Swift
// MARK: GMSMapViewDelegate
func mapView(_ mapView: GMSMapView, didChange position: GMSCameraPosition) {
marker.map = position.zoom >= 14 ? mapView : nil
}
Objective-C
// MARK: GMSMapViewDelegate
- (void)mapView:(GMSMapView *)mapView didChangeCameraPosition:(GMSCameraPosition *)position {
marker.map = position.zoom >= 14 ? mapView : nil;
}
마커를 드래그할 수 있도록 설정
draggable
속성을 사용 설정하면 사용자가 길게 누르기 동작으로 지도에서 마커를 드래그할 수 있습니다. 마커를 드래그 가능하도록 설정하려면 GMSMarker.draggable
속성을 true로 설정합니다.
Swift
marker.draggable = true
Objective-C
marker.draggable = YES;
