个别页面支持横竖屏

AppDelegate

AppDelegate.h
添加属性allowAcrolls

@interface AppDelegate : UIResponder <UIApplicationDelegate>
@property (strong, nonatomic) UIWindow * window;
@property (nonatomic,assign)BOOL allowAcrolls;//控制横竖屏显示
@endm

AppDelegate.m

- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(nullable UIWindow *)window
{
    if (self.allowAcrolls == NO) {//若游戏为横屏，此处不变，若游戏为竖屏，此处将NO改为YES
        //横屏
        return UIInterfaceOrientationMaskLandscape;
    }else{
        //竖屏
        return UIInterfaceOrientationMaskPortrait;
    }
}

使用场景

添加观察者

 // 横竖屏切换通知
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleScreenOrientationChange:) name:UIApplicationDidChangeStatusBarOrientationNotification object:nil];

#pragma mark ––––––––––––––––– 横竖屏切换通知
/// 横竖屏切换通知
- (void)handleScreenOrientationChange:(NSNotification *)noti {
    if ([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortrait || [UIApplication sharedApplication].statusBarOrientation == UIDeviceOrientationPortraitUpsideDown) {
        // 更新竖屏UI
        [self updateVerticalSubviews];
    } else {
        // 更新横屏UI
        [self updateHorizontalSubviews];
    }
}

移除观察者

 [[NSNotificationCenter defaultCenter] removeObserver:self
                                                       name:UIApplicationDidChangeStatusBarOrientationNotification
                                                  object:nil];

改变方向

//设置真机方向
- (void)setDeviceOrientation:(BOOL)isHorizontal{
    /**
     typedef NS_OPTIONS(NSUInteger, UIInterfaceOrientationMask) {
         UIInterfaceOrientationMaskPortrait // 设备(屏幕)直立
         UIInterfaceOrientationMaskLandscapeLeft 屏幕向左横置
         UIInterfaceOrientationMaskLandscapeRight 屏幕向右橫置
         UIInterfaceOrientationMaskPortraitUpsideDown 未知
         UIInterfaceOrientationMaskLandscape = (UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight),
         UIInterfaceOrientationMaskAll = (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskPortraitUpsideDown),
         UIInterfaceOrientationMaskAllButUpsideDown = (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight),
     }
