POST하는 방법 서버에 여러 개의 이미지가 있습니까?

서버에 여러 개의 이미지를 POST하려고하는데 서버로가는 이미지가 하나뿐입니다. 여러 이미지를 저장하려고합니다. 내 코드가 내가 잘못한 곳을 말해 준다. 여러 이미지를 게시하는 예를 보았습니다.POST하는 방법 서버에 여러 개의 이미지가 있습니까?

Upload multiple images in one request

답을 확인 했습니까? – Mukesh

image_name = [NSString stringWithFormat : @ "% @ % d", @ "image", y]; NSLog (@ "이미지 이름 : % @", image_name); UIImage * imageFile = [arrImage objectAtIndex : y]; 여기에 쓸 내용 nsdata 형식의 이미지가 있습니까? – user7356913

다음을 사용하여 NSData를 UiImage로 변경할 수 있습니다. NSData * data = yourImageData; UIImage * image = [[UIImage alloc] initWithData : data]; – Mukesh

POST하는 방법 서버에 여러 개의 이미지가 있습니까?
