如何使用弹出窗口行为全屏显示 ViewController？ Swift

Question

我需要全屏显示 VC，但可以在它弹出时向下滑动它，类似于它在 Apple Music 中的歌曲详细信息。

我已经尝试了 vc.modalPresentationStyle 中的所有选项，但要么全屏无法向下滑动关闭，要么有此功能但不能全屏

    vc.modalPresentationStyle = .overFullScreen
    vc.modalTransitionStyle = .coverVertical

Answer 1

你可以试试这个：

viewController.modalPresentationStyle = .fullScreen

Answer 2

设置modalPresentationStyle:

viewController.modalPresentationStyle = .formSheet

设置preferredContentSize:

viewController.preferredContentSize = CGSize(width: kScreenWidth, height: kScreenHeight)

Answer 3

所以，我只是全屏显示它并编写了函数，它允许平移关闭 vc，同时降低 alpha

func panToCloseGesture() {
        let panGesture = UIPanGestureRecognizer(target: self, action: #selector(handlePanGesture(_:)))
        view.addGestureRecognizer(panGesture)
    }
    
    @objc func handlePanGesture(_ sender: UIPanGestureRecognizer) {
        let percentThreshold:CGFloat = 0.3
        let translation = sender.translation(in: view)
        
        let newY = self.ensureRange(value: view.frame.minY + translation.y, minimum: 0, maximum: view.frame.maxY)
        let progress = self.progressAlongAxis(newY, view.bounds.height)
        
        view.frame.origin.y = newY
        if newY > 0 {
            self.rootView.alpha = 1 - (newY / 400)
        }
        
         if sender.state == .ended {
            let velocity = sender.velocity(in: view)
            if velocity.y >= 1000 || progress > percentThreshold {
                self.dismiss(animated: true, completion: nil)
            } else {
                UIView.animate(withDuration: 0.2, animations: {
                    self.rootView.alpha = 1
                    self.view.frame.origin.y = 0
                })
            }
        }
        sender.setTranslation(.zero, in: view)
    }
