내 응용 프로그램에서 위치 모니터링을 사용하려고합니다. 내 위치를 설정하고 모니터 할 위치를 역으로 바꿀 수 있습니다. didUpdateToLocation
대리자 메서드가 제대로 작동하고 계속 업데이트되지만 didStartMonitoingForRegion
대리자는 호출되지 않으며 didExitRegion
이나 didEnterRegion
도 호출되지 않습니다.CLLocation Manager didStartMonitoringForRegion 대리자 메서드가 호출되지 않았습니다.
제안 사항?

휴대 전화에서 앱이 잘 작동하지만 가끔 지오 펜스 횡단을 놓칠 수 있습니다. 그러나 새로운 "울타리"를 설정하면 올바르게 업데이트를 호출하더라도 거의 didStartMonitoingForRegion에 대한 호출이 표시되지 않습니다. – mflac
