3 개의 다른 JSON 연결을 수행하여 mapView에 마커가있는 세 개의 다른 MySQL 테이블을 채우려 고합니다.mapView에 마커를 표시하는 JSON 연결
이것은 지금 제가 수행 한 코드입니다. 연결을 테스트하기 위해 didReceiveData 메서드를 로깅하지만 컴파일러 커서가 해당 메서드에 도착하지 않으며 물론 모든 마커가지도에 표시됩니다.
내 코드를보고 내가 무엇을 놓치고 잘못했는지 알려주는 것이 좋습니다. 고맙습니다.

APP를 테스트하기위한 업데이트 된 코드.
테스트를 위해 코드를 업데이트 했으므로 이제는 두 개의 연결로만 작업하고 있습니다. 결과를 기록, 나는 배열 (first_connection에서) 제품 분류 및 (second_connection에서) categoria2이 (first_connection에서) 같은 JSON 파일에서 설치되었는지 감지 :

'initWithRequest'대신 'connectionWithRequest'를 사용할 수 있습니까? – user2071152
@ user2071152 고맙습니다. 지금 시도해 보겠습니다.하지만 문제가 아닌 것 같습니다. 처음에는 연결을 하나만 시도했지만 제대로 작동했습니다. – mvasco
@ user2071152 귀하의 제안은 컴파일러 오류를 발생시킵니다. – mvasco
