IOS9 Horizontal Screen Vertical screen setting

公司App里面有个需求，即所有界面都是竖屏，且不允许横屏切换，唯独有一个播放视频的界面允许横屏，大家都知道视频播放适配最大的播放屏幕那样是最好的。从网上多方查找资料，查到了这么一篇文章：

1. Ultimately, this needs to be handled as follows: first, make sure that the app itself should allow the switch to be turned on:
   

2. The Uitabbarcontroller in my app is the root view controller, so first create a Uitabbarcontroller subclass and set the Allow to turn screen:
   (These are placed in the root view controller, if your app root view is Uinavigationcontroller, just put it in there.)

#pragma mark 转屏方法重写-(UIInterfaceOrientationMask)supportedInterfaceOrientations{    return [self.viewControllers.firstObject supportedInterfaceOrientations];}-(BOOL)shouldAutorotate{    returnself.viewControllers.firstObject.shouldAutorotate;}

1. Then, in my Tabbarcontroller, each sub-controller is uinavigationcontroller for the interface push switch, so first create a uinavigationcontroller subclass, and set the Allow to turn the screen:

//self.topViewController是当前导航显示的UIViewController，这样就可以控制每个UIViewController所支持的方向啦！-(BOOL)shouldAutorotate{    return [self.topViewController shouldAutorotate];}- (UIInterfaceOrientationMask)supportedInterfaceOrientations {    return [self.topViewController supportedInterfaceOrientations];}

1. In the viewcontroller you want to switch the screen can be rewritten as such (allow left and right horizontal screen and vertical screen):

- (BOOL)shouldAutorotate {    return NO;}- (UIInterfaceOrientationMask)supportedInterfaceOrientations {    return UIInterfaceOrientationMaskPortrait;}

1. To the video playback interface to be set to horizontal screen (my video playback as long as the horizontal screen is good ^_^)

// 是否支持屏幕旋转- (BOOL)shouldAutorotate {    returnNO;}- (UIInterfaceOrientationMask)supportedInterfaceOrientations {    return UIInterfaceOrientationMaskLandscape;}-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {    return UIInterfaceOrientationLandscapeRight;}

Note: Jump to the player to use the modal, with push will error
[Self PRESENTVIEWCONTROLLER:PLAYERVC animated:yes completion:nil];
