本文介绍如何在iOS应用中实现特定视图控制器的方向锁定功能。针对PortraitViewController和LandscapeViewController两类场景，提供了iOS5及iOS6两个版本的代码实现，确保应用在期望的方向下运行。

1,PortraitViewController 不旋转，保持竖屏

//iOS 5
- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
	return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}
//iOS 6
- (BOOL)shouldAutorotate
{
	return NO;
}
- (NSUInteger)supportedInterfaceOrientations
{
	return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
	return UIInterfaceOrientationPortrait;
}

2.LandscapeViewController 始终保持横屏

//iOS 5
- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
	return (toInterfaceOrientation == self.preferredInterfaceOrientationForPresentation);
}
//iOS 6
- (BOOL) shouldAutorotate
{
	return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
	return UIInterfaceOrientationMaskLandscapeRight;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
	return UIInterfaceOrientationLandscapeRight;
}
