这对我很有效

let vc = self.storyboard?.instantiateViewController(withIdentifier: "storyboardID_cameraview1") as! CameraViewController
  
vc.modalPresentationStyle = .fullScreen
    
self.present(vc, animated: true, completion: nil)`

以上的答案和建议是正确的，下面是另一个版本，和有效的方法使用编程。

创建一个UIView扩展

创建一个方法()

//#1
extension UIViewController {

//#2
func presentLocal(_ viewControllerToPresent: UIViewController, animated flag: 
Bool, completion: (() -> Void)? = nil) {

//Reusing below 2 lines :-)
viewControllerToPresent.modalPresentationStyle = .overCurrentContext
self.present(viewControllerToPresent, animated: flag, completion: completion)

  }
}

调用如下所示

let vc = MyViewController()
let nc = UINavigationController(rootViewController: vc)
sourceView.presentLocal(nc, animated: true, completion: nil)

OR

let vc = MyViewController()
sourceView.presentLocal(vc, animated: true, completion: nil)

这很容易做到 打开你的故事板作为源代码，搜索kind="presentation"，在所有带有kind= presentation的segue标签中添加一个额外的属性modalPresentationStyle="fullScreen"

我通过使用方法swizzling(Swift 4.2)实现了它:

创建UIViewController扩展，如下所示

extension UIViewController {

    @objc private func swizzled_presentstyle(_ viewControllerToPresent: UIViewController, animated: Bool, completion: (() -> Void)?) {

        if #available(iOS 13.0, *) {
            if viewControllerToPresent.modalPresentationStyle == .automatic || viewControllerToPresent.modalPresentationStyle == .pageSheet {
                viewControllerToPresent.modalPresentationStyle = .fullScreen
            }
        }

        self.swizzled_presentstyle(viewControllerToPresent, animated: animated, completion: completion)
    }

     static func setPresentationStyle_fullScreen() {

        let instance: UIViewController = UIViewController()
        let aClass: AnyClass! = object_getClass(instance)

        let originalSelector = #selector(UIViewController.present(_:animated:completion:))
        let swizzledSelector = #selector(UIViewController.swizzled_presentstyle(_:animated:completion:))

        let originalMethod = class_getInstanceMethod(aClass, originalSelector)
        let swizzledMethod = class_getInstanceMethod(aClass, swizzledSelector)
        if let originalMethod = originalMethod, let swizzledMethod = swizzledMethod {
        method_exchangeImplementations(originalMethod, swizzledMethod)
        }
    }
}

在AppDelegate中，在application:didFinishLaunchingWithOptions中:调用swizzling代码通过调用:

UIViewController.setPresentationStyle_fullScreen()

class MyViewController: UIViewController {

    convenience init() {
        self.init(nibName:nil, bundle:nil)
        self.modalPresentationStyle = .fullScreen
    }

    override func viewDidLoad() {
        super.viewDidLoad()
    }
}

而不是调用self。modalPresentationStyle = . fullscreen对于每个视图控制器，你可以子类化UIViewController并在任何地方使用MyViewController。

let Obj = MtViewController()
Obj.modalPresentationStyle = .overFullScreen
self.present(Obj, animated: true, completion: nil)

//如果你想禁用滑动来消除它，添加行

Obj.isModalInPresentation = true
