ios swift play video uploaded from cloudkit - ios

Question

I am trying to play a video downloaded from cloudkit. I use the same query method that I use for downloading image:
publicData.performQuery(query, inZoneWithID: nil) { results, error in
if error == nil { // There is no error
for cafe in results! {
let newCafe = Cafe()
newCafe.address = cafe["address"] as? String
newCafe.name = cafe["name"] as? String
newCafe.email = cafe["email"] as? String
newCafe.description = cafe["description"] as? String
newCafe.location = cafe["location"] as? CLLocation
newCafe.cafeImage = cafe["cafeImage"] as? CKAsset
newCafe.offer_wifi = cafe["offer_wifi"] as? Bool
newCafe.smoking_area = cafe["smoking_area"] as? Bool
newCafe.cafeVideo = cafe["video"] as? CKAsset // <== I want to use this
self.cafes.append(newCafe)
let defaults: NSUserDefaults = NSUserDefaults.standardUserDefaults()
defaults.setInteger(self.cafes.count, forKey: "PreviousCafeCount")
dispatch_async(dispatch_get_main_queue(), { () -> Void in
self.tableView.reloadData()
Spinner.sharedLoader.hideLoading()
})
inside the cafeDetailViewController, I create a button that trigger playing a video using AVPlayer. AVKit and AVFoundation are already imported.
#IBAction func playVideo(sender: AnyObject) {
if let file = cafeDetail.cafeVideo {
let player = AVPlayer(URL: file.fileURL)
let playerController = AVPlayerViewController()
playerController.player = player
self.addChildViewController(playerController)
self.view.addSubview(playerController.view)
playerController.view.frame = self.view.frame
player.play()
}
}
However the result is this:
follow up question: how can I implement model association in swift? Similar to has_many and belongs_to association in rails. I don't think downloading the whole video beforehand is a good solution.

From what I can see, you need to save the video to a local file and then play that file. This is modified from something I wrote to mess around with CloudKit.
import UIKit
import CloudKit
import AVKit
import AVFoundation
class CloudKitTestViewController: UIViewController {
let publicDatabase = CKContainer.defaultContainer().publicCloudDatabase
var videoURL: NSURL!
#IBAction func load(sender: AnyObject) {
let predicate = NSPredicate(format: "videoName = %#", "nameOfVideoGoesHere")
activityIndicator.startAnimating()
let query = CKQuery(recordType: "Videos", predicate: predicate)
publicDatabase.performQuery(query, inZoneWithID: nil) { (results, error) in
if error != nil {
dispatch_async(dispatch_get_main_queue()) {
self.notifyUser("Cloud Access Error",
message: error!.localizedDescription)
}
} else {
if results!.count > 0 {
let record = results![0]
dispatch_async(dispatch_get_main_queue()) {
!)
let video = record.objectForKey("videoVideo") as! CKAsset
self.videoURL = video.fileURL
let videoData = NSData(contentsOfURL: self.videoURL!)
let documentsPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0]
let destinationPath = NSURL(fileURLWithPath: documentsPath).URLByAppendingPathComponent("filename.mov", isDirectory: false)
NSFileManager.defaultManager().createFileAtPath(destinationPath.path!, contents:videoData, attributes:nil)
self.videoURL = destinationPath
print(self.videoURL)
}
} else {
dispatch_async(dispatch_get_main_queue()) {
self.notifyUser("No Match Found",
message: "No record matching the address was found")
}
}
}
dispatch_async(dispatch_get_main_queue(), {
self.activityIndicator.stopAnimating()
})
}
}
override func prepareForSegue(segue: UIStoryboardSegue,
sender: AnyObject?) {
let destination = segue.destinationViewController as!
AVPlayerViewController
let url = videoURL
print(videoURL)
destination.player = AVPlayer(URL: url!)
}
}
