iOS项目（Swift4.2）采用形式，界面默认竖屏，如何设置某些特定界面横竖屏可切换或者强制横屏？

Question

问题描述

App使用TabbarController->NavigationController->ViewController架构，想整体界面默认竖屏，然后一些特定界面可支持横竖屏切换或者强制横屏。

问题出现的环境背景及自己尝试过哪些方法

相关代码

在自定义UINavigationController中

override var shouldAutorotate: Bool {
        return self.topViewController?.shouldAutorotate ?? false
    }

    override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
        return self.topViewController?.supportedInterfaceOrientations ?? .portrait
    }

    override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation {
        return self.topViewController?.preferredInterfaceOrientationForPresentation ?? .portrait
    }

自定义UITabBarController中：

override var shouldAutorotate: Bool {
        return self.selectedViewController?.shouldAutorotate ?? false
        
    }
    
    override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
        return self.selectedViewController?.supportedInterfaceOrientations ?? .portrait
    }
    
    override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation {
        return self.selectedViewController?.preferredInterfaceOrientationForPresentation ?? .portrait
    }

然后我现在的做法是，在只希望竖屏的VC中：

override var shouldAutorotate: Bool {
        return false
    }
    
    override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
        return .portrait
    }
    
    override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation {
        return .portrait
    }

在只希望横屏的VC中：

override var shouldAutorotate: Bool {
        return true
    }
    
    override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
        return [.landscapeRight, .landscapeLeft]
    }
    
    override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation {
        return .landscapeRight
    }

在横竖屏可切换的VC中：

override var shouldAutorotate: Bool {
        return true
    }
    
    override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
        return .allButUpsideDown
    }
    
    override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation {
        return .landscapeLeft
    }

项目的info.plist中都勾选了横竖屏。这样试下来出现了几个bug，其中一个是从竖屏界面push到可横竖屏切换的界面，然后在该界面横屏时侧滑返回，而后再在第一个界面上push，再次侧滑返回时侧滑返回的动画消失，转场效果很突兀。

有没有完美的解决方案啊？重谢！
