iphone에서 화면에 대한 회전을 시키기 위한 간단한 코드는..

[[UIDevice currentDevice] setOrientation:orientation] 이다.

하지만, 이 코드는 non-public API 사용으로 인한 리젝 사유가 되므로 사용할 수 없기 때문에 아래와 같이 회전 관련 메서드를 만들어주어야 한다.

//화면 회전 처리

-(void)SetDeviceOrientation:(UIInterfaceOrientation)orientation
{
	
	//가로보기 강제
	if(orientation==UIInterfaceOrientationPortrait)
	{
		orientation=UIInterfaceOrientationLandscapeRight;
	}
	//세로보기 강제
	else if(orientation==UIInterfaceOrientationLandscapeRight)
	{
		orientation=UIInterfaceOrientationPortrait;			
	}	
	
	
	int radian=0;
	CGRect viewFrame = CGRectMake(0.0f, 0.0f, 320.0f, 480.0f);
	
	[UIView beginAnimations:nil context:nil];
	[UIView setAnimationDuration: 0.2];
	
	if(orientation==UIInterfaceOrientationLandscapeLeft
	   || orientation==UIInterfaceOrientationLandscapeRight)
	{
		viewFrame = CGRectMake(0.0f, 0.0f, 480.0f, 320.0f);
		
	}	
	if(orientation==UIInterfaceOrientationPortrait)
	{
		radian=0;
	}
	else if(orientation==UIInterfaceOrientationPortraitUpsideDown)
	{
		radian=180;
	}
	else if(orientation==UIInterfaceOrientationLandscapeRight)
	{
		radian=90;
	}
	else if(orientation==UIInterfaceOrientationLandscapeLeft)
	{
		radian=270;
	}
	
	//뷰 회전 시키기
	CGAffineTransform transform =
	CGAffineTransformMakeRotation(degreesToRadian(radian));
	
	self.view.transform=transform;
	self.view.bounds=viewFrame;
	
	[UIView commitAnimations];
}
