iOS RxAction (RxSwift Community)

iOS RxAction (RxSwift Community)

 

RxSwift를 사용하면서 모든 챕터를 다 알아두면 좋을 것 같아서 보게 되었음.

이거 좀 유용할 것 같다는 생각이 든달까?

 

RxSwift Communtiry에 Pinned도 되어있음

2022.01.19 기준

샘플 예시

 

아주 간단한 예시이고, RefreshControl에서도 사용할 수 있음

RxCommunity - Action 부분에서 Tests를 가보면 다른 예시도 볼 수 있으니까 궁금하면 확인해보기!!

        }

        button2.rx.bind(to: action2, input: "say Hello?")
        button3.rx.bind(to: action3, input: "Button3")
    }
