Api-V2를 사용하여 Google지도를 새로 고침 하시겠습니까?

Question

Google지도에 Google Api 버전 2를 사용하고 있습니다. Google지도를 새로 고치고 싶습니다. API 버전 2를 사용하여 새로 고칠 수 있습니까? api-v2에서 VisualRefresh 옵션을 사용할 수 있습니까? 난 단지 자바 코드 또는 가능한에서 자바 스크립트 경우를 사용하여 몇 가지 아이디어를 제안하십시오 (무효화)하지만보기에 적용하여 시도

내 코드는?

Answer 1

this library처럼 보입니다. 코드보고에서, 업데이트를 강제로처럼 보이는, 당신은 전화를 할 것입니다 : 다시 클러스터해야보기에서 모든 것을

clusterer.forceUpdate()

합니다.
