가로 모드에서 서명 상자가 올바르게 표시되지 않습니다.

Question

사용자가 이름에 서명 할 수있는 이미지 프레임 (흰색 상자)을 만드는보기 컨트롤러가 있습니다. ipad의 세로 모드에서는 정상적으로 작동하지만 가로 모드에서 로그인하면 화면 왼쪽 하단에 상자가 나타납니다. 중앙처럼 보이지 않아야합니다.

아래 코드를 사용했지만 도움이나 제안을 보내 주시면 감사하겠습니다.

AppDelegate *appDelegate = 
[[UIApplication sharedApplication] delegate]; 

// //create a frame for our signature capture based on whats remaining 
imageFrame      = CGRectMake(appDelegate.window.center.x, 
               appDelegate.window.center.y, 
               appDelegate.window.size.width, 
               appDelegate.window.bounds.size.width/1.5);
