使用 uiactivityViewcontroller 共享视频答案

【问题标题】：sharing video using uiactivityViewcontroller使用 uiactivityViewcontroller 共享视频

【问题描述】：

我正在开发一个应用程序，并希望使用 uiactivityviewcontroller 共享保存在我的文档目录中的图像视频和其他文件。图像和文件共享工作正常。图片分享代码

var textToShare : Any!
textToShare = UIImage(data:data)//data of an image

存储在文档目录中的其他文件的代码。

var textToShare : Any!
textToShare = url//url of file saved into document directory

但我不知道如何分享视频。在这之后我使用以下代码来使用activityviewcontroller。

let activityViewController = UIActivityViewController(activityItems: [textToShare], applicationActivities: nil)
    activityViewController.popoverPresentationController?.sourceView = self.view // so that iPads won't crash

    // exclude some activity types from the list (optional)
    activityViewController.excludedActivityTypes = [ UIActivityType.airDrop, UIActivityType.postToFacebook ]

    // present the view controller
    self.present(activityViewController, animated: true, completion: nil)

【解决方案1】：

首先获取视频文件路径

 let videoURL = NSURL(fileURLWithPath:localVideoPath)

然后将此路径传递给UIActivityViewController，如下所示

let activityItems = [videoURL, "Check this out!" ]
let activityController = UIActivityViewController(activityItems: activityItems, applicationActivities: nil)

activityController.popoverPresentationController?.sourceView = self.view
activityController.popoverPresentationController?.sourceRect = self.view.frame

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

更新了 Swift 4 的代码

    let localVideoPath = "your_video_path_here..."
    let videoURL = URL(fileURLWithPath: localVideoPath)

    let activityItems: [Any] = [videoURL, "Check this out!"]
    let activityController = UIActivityViewController(activityItems: activityItems, applicationActivities: nil)

    activityController.popoverPresentationController?.sourceView = view
    activityController.popoverPresentationController?.sourceRect = view.frame

    self.present(activityController, animated: true, completion: nil)

我已经有视频 url 但它没有存储在本地路径中。它被保存到图库中。我需要先导出它。你能解释一下如何导出视频吗？我已经尝试过了，但无法分享视频。
是的，可以使用画廊提供的路径。你在用 UIImagePickerController 吗？
不，现在我正在使用 phasset 获取存储到图库中的所有视频的 url。将来我想打开 UiImagePickerController 但现在我只有视频的 url，我想导出它。如果无法仅使用 url 导出它，请告诉我。我将更改我的代码以使用 UiImagePickerController。谢谢你:)
我已将代码更改为 uiImagePicker，您能告诉我现在如何分享吗？
你的方法适用于 uiimagepickercontroller 谢谢 :)

从本地文档目录路径分享视频

func shareVideo(videoPath : String){
        let localVideoPath = videoPath
        let videoURL = URL(fileURLWithPath: localVideoPath)

        let activityItems: [AnyObject] = [videoURL as AnyObject]
        let activityController = UIActivityViewController(activityItems: activityItems, applicationActivities: nil)

        activityController.popoverPresentationController?.sourceView = view
        activityController.popoverPresentationController?.sourceRect = view.frame

        self.present(activityController, animated: true, completion: nil)
    }

Swift 5.0 // 带有 FileManager 和文件名的方法

  let localVideoPath = "video_file_name.mp4" // NAME OF THE VIDEO FILE
                
    if let dir = try? FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false) {
                   
      let videoURL = URL(fileURLWithPath: dir.absoluteString).appendingPathComponent(localVideoPath)

      let activityItems: [Any] = [videoURL]
      let activityController = UIActivityViewController(activityItems: activityItems, applicationActivities: nil)

      activityController.popoverPresentationController?.sourceView = view
      activityController.popoverPresentationController?.sourceRect = view.frame
      self.present(activityController, animated: true, completion: nil)
   }

func shareUsingActivity() {

    let yourPath = ""
    let yourUrl = URL(fileURLWithPath: yourPath)
    let activity: [Any] = [yourUrl, "Your custom message here…"]
    let actController = UIActivityViewController(activity: activity, applicationActivities: nil)
    actController.popoverPresentationController?.sourceView = view
    actController.popoverPresentationController?.sourceRect = view.frame
    self.present(actController, animated: true, completion: nil)
}
