Access to the iOS library library

After the user has given us permission to access his Camera Roll. We would like to capture data and upload it to our services from our application. Is there a way to access video data from a file? The only way to open the video file is to create AVAsset. But that is not enough for me.

I know

func requestExportSessionForVideo(_ asset: PHAsset!,
                      options options: PHVideoRequestOptions!,
                 exportPreset exportPreset: String!,
                resultHandler resultHandler: ((AVAssetExportSession!,
                    [NSObject : AnyObject]!) -> Void)!) -> PHImageRequestID

But in my case, I just want to upload a video to our service, which I do not want to do:

  • first copy the video by exporting to my local application data.
  • and then send this data to our service.
  • delete data.

This approach above uses a lot of extra space and time, and users with full 16-gigabyte iPhones do not work.

Ok, this is what I tried using using url

var anAcces = sourceURL?.startAccessingSecurityScopedResource

if !NSFileManager.defaultManager().fileExistsAtPath(sourceURL!.path!) {
    NSLog("not exist")
}

var aFileCoordinator = NSFileCoordinator(filePresenter:nil)
var anError: NSError?

aFileCoordinator.coordinateReadingItemAtURL(sourceURL!, options:.ForUploading, error:&anError, byAccessor:  { (newURL: NSURL!) -> Void in
    var data = NSData(contentsOfURL: newURL)
    })
if let unError = anError {
    NSLog("Error \(unError)")
}

sourceURL?.stopAccessingSecurityScopedResource

The following data is written here:

2015-02-08 16:20:01.947 Cameo[15706:2288691] not exist
