ios中横屏和竖屏如何共存??

ios中可以设置是横屏还是竖屏。但如果你在xcode中同时选择了横屏和竖屏,当你旋转屏幕时,你的view就会同时就会跟着旋转。我现在的问题时,我的app要有两个view,一个是支持横屏的,但它不能选择,永远横屏。另外一个是竖屏的,永远是竖屏的,也不能再选择。两个view通过一个button关联,点一下,进入另一个。


没地方放压缩包,我就在这里写个简单吧,2个UIViewController,你自己新建一个工程就加两按钮就可以测试。
核心需要添加的方法如下:

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;
}

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;
}
