视频播放想要全屏，使用shouldAutorotate方法禁止主界面，tabbar控制器横屏，导致push进入播放页面不能横屏的问题。。。

- (BOOL)shouldAutorotate {

    return NO;

}

- (UIInterfaceOrientationMask)supportedInterfaceOrientations {

    return UIInterfaceOrientationMaskAll;

}

后面解决方法：

- (void)fullScreenClick:(UIButton *)sender {

    sender.selected = !sender.selected;

    if (sender.isSelected) {

        _backButton.hidden = YES;

        [self forceOrientationLandscapeLeft];

    } else {

        _backButton.hidden = NO;

        [self forceOrientationPortrait];

    }

}

//MARK: -- 强制横屏

- (void)forceOrientationLandscapeLeft

{

    AppDelegate *appdelegate=(AppDelegate *)[UIApplication sharedApplication].delegate;

    appdelegate.isForcePortrait=NO;

    appdelegate.isForceLandscape=YES;

    [appdelegate application:[UIApplication sharedApplication] supportedInterfaceOrientationsForWindow:self.view.window];

    YNCNavigationViewController *navi = (YNCNavigationViewController *)self.navigationController;

    navi.interfaceOrientation = UIInterfaceOrientationMaskLandscape;

    navi.interfaceOrientationMask = UIInterfaceOrientationMaskLandscape;

    //设置屏幕的转向为横屏

    [[UIDevice currentDevice] setValue:@(UIDeviceOrientationLandscapeLeft) forKey:@"orientation"];

    //刷新

    [UIViewController attemptRotationToDeviceOrientation];

}

//MARK: -- 强制竖屏

- (void)forceOrientationPortrait

{

    AppDelegate *appdelegate=(AppDelegate *)[UIApplication sharedApplication].delegate;

    appdelegate.isForcePortrait=YES;

    appdelegate.isForceLandscape=NO;

    [appdelegate application:[UIApplication sharedApplication] supportedInterfaceOrientationsForWindow:self.view.window];

    YNCNavigationViewController *navi = (YNCNavigationViewController *)self.navigationController;

    navi.interfaceOrientation = UIInterfaceOrientationPortrait;

    navi.interfaceOrientationMask = UIInterfaceOrientationMaskPortrait;

    //设置屏幕的转向为竖屏

    [[UIDevice currentDevice] setValue:@(UIDeviceOrientationPortrait) forKey:@"orientation"];

    //刷新

    [UIViewController attemptRotationToDeviceOrientation];

}
