schnelles Video in Dokumentenverzeichnis

Question

Ich brauche Video mit UIImagePicker in einem benutzerdefinierten Ordner in app Dokumentenverzeichnis

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) { 
    picker.dismissViewControllerAnimated(true, completion: nil) 
    if let fileURL = info[UIImagePickerControllerMediaURL] as? NSURL { 
     if let videoData = NSData(contentsOfURL: fileURL) { 
      //save file to doc dir or save NSData into Core Data binary field 

     } 
    } 
} 

alternativ gefangen speichern wir Videodaten in Core Data binärem Feld mit externen Speichern speichern können, aber nachdem ich kann nicht Spielen Sie das Video mit dem Media Player ab, da ich NSData nicht in NSURL konvertieren kann.

Answer 1

Versuchen Sie dies. Swift 2.2

var uniqueVideoID = "" 
    var videoURL: NSURL? = NSURL() 
    var uniqueID = "" 

    //Add this to ViewDidLoad 
    uniqueID = NSUUID().UUIDString 

      //Getting the path as URL and storing the data in myVideoVarData. 
     videoURL = info[UIImagePickerControllerMediaURL] as? NSURL 
     let myVideoVarData = NSData(contentsOfURL: videoURL!)! 

     //Now writeing the data to the temp diroctory. 
     let tempPath = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true) 
     let tempDocumentsDirectory: AnyObject = tempPath[0] 
      uniqueVideoID = uniqueID + "TEMPVIDEO.MOV" 
     let tempDataPath = tempDocumentsDirectory.stringByAppendingPathComponent(uniqueVideoID) 
      myVideoVarData.writeToFile(tempDataPath, atomically: false) 

     //Getting the time value of the movie. 
     let fileURL = NSURL(fileURLWithPath: tempDataPath) 
     let asset = AVAsset(URL: fileURL) 
     let duration : CMTime = asset.duration 


     //Now we remove the data from the temp Document Diroctory. 
     do{ 
     let fileManager = NSFileManager.defaultManager() 
     try fileManager.removeItemAtPath(tempDataPath) 
     } catch { 
      //Do nothing 
     } 

     // Cheacking to see if video is under the 18500 (:30 seconds). 
     if duration.value <= 18500 { 


     //Here we are writing the data to the Document Directory for use later on. 
     let docPaths = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true) 
     let documentsDirectory: AnyObject = docPaths[0] 
      uniqueVideoID = uniqueID + "VIDEO.MOV" 
     let docDataPath = documentsDirectory.stringByAppendingPathComponent(uniqueVideoID) 
      myVideoVarData.writeToFile(docDataPath, atomically: false) 
      print("docDataPath under picker ",docDataPath) 

     //This creates a thumbnail image. 
     let assetImageGenerate = AVAssetImageGenerator(asset: asset) 
      assetImageGenerate.appliesPreferredTrackTransform = true 
     let time = CMTimeMake(asset.duration.value/3, asset.duration.timescale) 

     //This adds the thumbnail to the imageview. 
     if let videoImage = try? assetImageGenerate.copyCGImageAtTime(time, actualTime: nil) { 
      videoThumbnailOutlet.image = UIImage(CGImage: videoImage) 
      } 
     }else{ 
      //Do nothing 
    } 

Jetzt spielen Sie das Video.

//Note: The _videoData_ is the same as the _uniqueID_ 
    var videoData = "" 


    func play(){ 

    let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true) 
    let documentsDirectory = paths[0] 

    let videoDataPath = documentsDirectory + "/" + videoData + "VIDEO.MOV" 

    let filePathURL = NSURL.fileURLWithPath(videoDataPath) 


    let player = AVPlayer(URL: filePathURL) 
    let playerController = AVPlayerViewController() 
     playerController.player = player 
    self.presentViewController(playerController, animated: true) { 
     player.play() 


    } 
    }
