IOS 모방 경 동 주소 선택 기

프로젝트 는 주소 선택 기 가 필요 합 니 다. 동적 네트워크 나 로 컬 데이터 베이스 에서 다음 주 소 를 가 져 와 야 합 니 다. 그리고 우연히 경 동의 주소 선택 기 가 좋 은 것 을 보고 모방 하 였 습 니 다.디자인 모드 는 UItableView 의 데이터 원본 과 프 록 시 모드 를 모방 한 것 입 니 다. 그 중에서 데이터 원본 이 block 으로 되 돌아 갈 수 있 는 데이터 원본 은 네트워크 요청 이기 때문에 block 으로 되 돌 리 는 것 이 편리 합 니 다.코드 는 다음 과 같 습 니 다:
