IOS开发-在UIViewController中锁定竖屏

转自：http://www.jianshu.com/p/6ebfc7294e13

因为APP中有视频播放，所以不能全局锁定，只能在一些实在不想横屏的Controller中进行锁定

代码如下：

    override func shouldAutorotate() -> Bool {        return false    }    override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {        return UIInterfaceOrientationMask.Portrait    }    override func preferredInterfaceOrientationForPresentation() -> UIInterfaceOrientation {        return UIInterfaceOrientation.Portrait    }
