Xcode - 분할 컨트롤이 기본값으로 변경

Question

두 개의보기 컨트롤러가있는 xcode 응용 프로그램이 있습니다. 두 개의 단추가 있습니다 (첫 번째 단추는 alertview를 표시하는 단추이고 두 번째 단추는 두 개의 단추 사이에 이동하는 단추입니다. 보기). 두 번째보기에서 나는 4 개의 세그먼트가있는 세그먼트 컨트롤러가 있고 그 중 하나를 선택하면 첫 번째보기로 돌아가서 세그먼트 컨트롤러보기로 돌아갑니다. 세그먼트 컨트롤러는 첫 번째 세그먼트로 돌아갑니다 ... 어떻게 수정합니까? 이 ? 나는 당신의 질문을 이해한다면 여기

의 코드이며,이 당신의 대답 일 것이다.

@interface firstViewController : UIViewController{ 

    firstViewController *secondView; 
} 

//add this where you push to the secondView 

if(!secondView) 
    secondView = [[secondViewController alloc] init]; 
//This will init the second view only one time. So the position of your segments will retain its state. 
    [[self navigationController]pushViewController:photocontent animated:YES]
