Swift 2 - Share Video Using UIActivityViewController

Question

I am trying to share a video with a url using UIActivityViewController. If I try with the image, I have no problem.

Image Sharing:

let imageThump = NSURL(string: "https://example.com/image.png")
        let imageData = NSData(contentsOfURL: imageThump!) 
let objectsToShare = [comment!, imageData!]
            let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)

Share Video does not work. Why?

let videoShare = NSURL(string: "https://example.com/video.mp4")
        let videoData = NSData(contentsOfURL: videoShare!) 
let objectsToShare = [comment!, videoData!]
            let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)

Answer 1

THIS HOW YOU ARE THIS ...

  let urlData = NSData(contentsOfURL: NSURL(string:"https://example.com/video.mov)")!)

            if ((urlData) != nil){

                print(urlData)


                let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
                let docDirectory = paths[0]
                let filePath = "\(docDirectory)/tmpVideo.mov"
                urlData?.writeToFile(filePath, atomically: true)
                // file saved

                let videoLink = NSURL(fileURLWithPath: filePath)


                let objectsToShare = [videoLink] //comment!, imageData!, myWebsite!]
                let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)

                activityVC.setValue("Video", forKey: "subject")


                //New Excluded Activities Code
                if #available(iOS 9.0, *) {
                    activityVC.excludedActivityTypes = [UIActivityTypeAirDrop, UIActivityTypeAddToReadingList, UIActivityTypeAssignToContact, UIActivityTypeCopyToPasteboard, UIActivityTypeMail, UIActivityTypeMessage, UIActivityTypeOpenInIBooks, UIActivityTypePostToTencentWeibo, UIActivityTypePostToVimeo, UIActivityTypePostToWeibo, UIActivityTypePrint]
                } else {
                    // Fallback on earlier versions
                    activityVC.excludedActivityTypes = [UIActivityTypeAirDrop, UIActivityTypeAddToReadingList, UIActivityTypeAssignToContact, UIActivityTypeCopyToPasteboard, UIActivityTypeMail, UIActivityTypeMessage, UIActivityTypePostToTencentWeibo, UIActivityTypePostToVimeo, UIActivityTypePostToWeibo, UIActivityTypePrint ]
                }


                self.presentViewController(activityVC, animated: true, completion: nil)
            }

Remember that a video is usually a large file, so it will take some time to download and save it. Here I used part of the first answer, but added some GCD. You will get the best results.

, , :

    let url = NSURL(string:"https://example.com/video.mov)"

    //Show activity indicator

     DispatchQueue.global(qos: .background).async {
         if let urlData = NSData(contentsOf: url){
           let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]
              let filePath="\(documentsPath)/tempFile.mov"
              DispatchQueue.main.async {
                urlData.write(toFile: filePath, atomically: true)

                //Hide activity indicator

                let activityVC = UIActivityViewController(activityItems: [NSURL(fileURLWithPath: filePath)], applicationActivities: nil)
                activityVC.excludedActivityTypes = [.addToReadingList, .assignToContact]
                self.present(activityVC, animated: true, completion: nil)
              }
          }
      }

 let urlData = NSData(contentsOf: NSURL(string:"https://example.com/video.mov")! as URL)

    if ((urlData) != nil){

        print(urlData)


        let paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
        let docDirectory = paths[0]
        let filePath = "\(docDirectory)/tmpVideo.mov"
        urlData?.write(toFile: filePath, atomically: true)
        // file saved

        let videoLink = NSURL(fileURLWithPath: filePath)


        let objectsToShare = [videoLink] //comment!, imageData!, myWebsite!]
