iPhone 이벤트가 약 회전하고 있습니까?

Question

내 응용 프로그램에서 내보기 회전 전에 일부 처리를하고 싶습니다. 회전이 발생하기 바로 전에 발생하는 이벤트가 있습니까?

감사합니다, 회전하는 동안 트리거의 UIViewController의 이벤트의 숫자가 있습니다 앨런

체크 아웃의 UIViewController의 이러한 방법 :

http://developer.apple.com/library/ios/#documentation/uikit/reference/UIViewController_Class/Reference/Reference.html

// Notifies when rotation begins, reaches halfway point and ends. 
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration; 


- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation; 

// Faster one-part variant, called from within a rotating animation block, for additional animations during rotation. 
// A subclass may override this method, or the two-part variants below, but not both. 
- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0); 

// Slower two-part variant, called from within a rotating animation block, for additional animations during rotation. 
// A subclass may override these methods, or the one-part variant above, but not both. 
- (void)willAnimateFirstHalfOfRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration; 
- (void)didAnimateFirstHalfOfRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation; // The rotating header and footer views are offscreen. 
- (void)willAnimateSecondHalfOfRotationFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation duration:(NSTimeInterval)duration; // A this point, our view orientation is set to the new orientation.

. 회전하기 전에 다음 두 트리거 :

- (void) willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation 

"단지 사용자 인터페이스가 회전을 시작하기 전에 뷰 컨트롤러로 전송."

- (void) willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration 

"한 단계 사용자 인터페이스 회전을 수행하기 전에보기 컨트롤러로 보냈습니다."
