如何在iPad中全屏显示UIVideoEditorViewController

Question

我已经使用UIVideoEditorViewController裁剪选定的视频。问题是，在iPad中，editorController必须以弹出样式呈现。当我在iPad上运行它时，编辑器视图在左角弹出，而不是全屏。有没有办法让popover视图全屏显示？谢谢

    if UIVideoEditorController.canEditVideoAtPath(tmp) {
        editVideoViewController = self.storyboard?.instantiateViewControllerWithIdentifier("editorVC") as! EditorViewController
        editVideoViewController.delegate = self
        editVideoViewController.videoPath = tmp
        editVideoViewController.videoMaximumDuration = 30
        editVideoViewController.videoQuality = .TypeHigh
        editVideoViewController.modalPresentationStyle = UIModalPresentationStyle.Popover

        editVideoViewController.popoverPresentationController?.sourceView = editVideoViewController.view

        self.presentViewController(editVideoViewController, animated: true, completion: nil)

    }

没有办法全屏显示UIVideoEditorController。您可以将其放入某个container控制器中。然后使用屏幕边界配置这个容器控制器preferredContentSize。你将得到几乎全屏大小的弹出窗口。

let containerVC = UIViewController()
containerVC.preferredContentSize = UIScreen.main.bounds.size
containerVC.modalPresentationStyle = .popover
let ppc = containerVC.popoverPresentationController
ppc?.delegate = self
ppc?.sourceView = containerVC.view
ppc?.sourceRect = UIScreen.main.bounds
ppc?.permittedArrowDirections = .init(rawValue: 0 )
ppc?.canOverlapSourceViewRect = true

let videoController = UIVideoEditorController()

containerVC.addChild(videoController)
containerVC.view.addSubview(videoController.view)
videoController.didMove(toParent: containerVC)

self.present(containerVC, animated: true)
