단추 누르기 직후 키보드 닫기

Question

UITextField에서 IP 주소를 입력 한 후 서버에 XMLRPC 호출을하는 "getResponse"단추가 있습니다. "getResponse"버튼과 같은 ID를 사용하면 먼저 키보드를 누른 후 서버에 전화를 건 경우 키보드를 종료합니다.

키보드가 켜져 있으면 서버를 호출하고 유효한 서버를 찾지 못하면 정보 또는 오류를 검색 한 다음 키보드를 종료합니다.

나는 그것의 아마 아마 쉬운 것을 알고있다. 그러나 나는 그것을 이해할 수 없다. 어떤 도움이라도 좋을 것입니다, 고마워요!

대신

[self serverInputReturn:self]; 

의 당신은의 UITextField하지 UIViewController에 전달해야

[self serverInputReturn:self.serverInput]; 

보십시오.

하면 더 많은 정보를 필요

self.serverInput.delegate = self;
