Save the video in the gallery and save the path to the video.

Question

I have an application in which the user can record video, this video is saved in the photo gallery, and I save the path to the video so that in the future the user can see the video inside the application again. The problem is that the method I use, I think that it gives me some kind of temporary path, and after a few days the video is still in the gallery, but the path is already invalid and makes the application crash. This is the code I'm using:

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
    let mediaType: String = info["UIImagePickerControllerMediaType"] as! String
    if mediaType == "public.movie" {
        let tempImageURL = info[UIImagePickerControllerMediaURL] as! NSURL!
        let pathString = tempImageURL.relativeString
        self.dismissViewControllerAnimated(true, completion: {})
        if picker.sourceType == UIImagePickerControllerSourceType.PhotoLibrary {
            self.videoPath = pathString
            // Save the path in the DB
        } else {
            VideoManager.saveVideo(tempImageURL, onComplete: { (path) -> Void in
                self.videoPath = path
                // Save the path in the DB
            })
            var fileManager: NSFileManager = NSFileManager()
            fileManager.removeItemAtPath(pathString!, error: nil)
        }
    }
}

And the code of the VideoManager.saveVideo method looks like this:

func saveVideo(videoURL: NSURL, onComplete:((path: String) -> Void)) {
    var assetsLibrary: ALAssetsLibrary = ALAssetsLibrary()
    assetsLibrary.writeVideoAtPathToSavedPhotosAlbum(videoURL, completionBlock: { (assetURL: NSURL!, error: NSError!) -> Void in
        var path: String = error == nil ? "\(assetURL)" : kEmptyString
        onComplete(path: path)
    })
}

I don't know what I'm doing wrong, I tried using the UISaveVideoAtPathToSavedPhotosAlbum method, but to no avail .. Any ideas?

For more information, when a video is selected from the gallery, the url I get is similar to the following:

file:///private/var/mobile/Containers/Data/Application/D2E8E31B-CEA0-43B0-8EF9-1820F6BDE4A9/tmp/trim.AD855155-AB78-4A16-9AA8-DF2B3F39824E.MOV

, URL:

file:///private/var/mobile/Containers/Data/Application/D2E8E31B-CEA0-43B0-8EF9-1820F6BDE4A9/tmp/capture/capturedvideo.MOV

VideoAtPathToSavedPhotosAlbum, URL-, :

assets-library://asset/asset.MOV?id=958507B5-1353-4DDC-BC07-D9CBC6126657&ext=MOV
