ios中单个页面强制横屏！

代码如下(实现右横屏),注意这个页面必须用present的方式推出.

(而且是必须present这个VC, 不能present被导航控制器管理的VC)

-(BOOL)shouldAutorotate

{

return NO;

}

-(UIInterfaceOrientationMask)supportedInterfaceOrientations

{

return UIInterfaceOrientationMaskLandscape;

}

-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation

{

return UIInterfaceOrientationLandscapeRight;

}

（根视图到A,A present B）代码添加在B中！
