스 와이프를 수행 한 방향을 인식하고 내 뷰에서 어떤 객체를 보냈는지 알 필요가 있습니다. 지금 당장 해결 방법을 찾았지만 복잡하고 괴물처럼 보이므로 가장 간단한 해결책이 있을까요? 몇 마디 내 해결 방법 :UIButton 객체와 함께 스 와이프 방향을 인식합니다.
- 내 인식의 모든 UIButton 개체에 연결된 인식자를 첨부했습니다.
- 스 와이프를 수행하는 동안 어떤 버튼이 두드려 졌는지 표시하는 표시기가 있습니다.
- 이 표시기를 확인하고 정확한 결정을 내리기 위해 방향을 스 와이프해야합니다. 어떤 오브젝트와 방향으로 이동해야합니까?
감사합니다.

우리가 touchUpoutside로 등록한다면, 어떻게 uibutton에서 single press (touchUpInside)가 작동하는가? 어떤 방식 으로든 작업을 시도한 사람이 없습니다. @vignesh – Sanju
