Integrate iAd pre-roll video integration in my app? - swift

Question

I want to integrate an iAd Pre-Roll video Ad to my application. When I run this application, it gives me this error:
Domain=ADErrorDomain Code=0 "The operation couldn’t be completed. (ADErrorDomain error 0.)
I want to know if this code is correct or incorrect. Thanks for your help.
import UIKit
import MediaPlayer
import iAd
class ViewController: UIViewController {
var moviePlayer : MPMoviePlayerController!
override func viewDidLoad() {
super.viewDidLoad()
let url = NSBundle.mainBundle().URLForResource("intro", withExtension: "mp4")
moviePlayer = MPMoviePlayerController(contentURL: url)
moviePlayer!.view.frame = view.frame
moviePlayer!.prepareToPlay()
view.addSubview(moviePlayer!.view!)
moviePlayer.playPrerollAdWithCompletionHandler { (error) -> Void in
NSLog("\(error)")
self.moviePlayer.play()
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
This is one of my modified App Delegate function:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
MPMoviePlayerController.preparePrerollAds()
return true
}

You're trying to display your Pre-Roll Video Ad before your application has had any time to download it. Fire your moviePlayer.playPrerollAdWithCompletionHandler after a few seconds or move the video to a later point in your intro so your application has time to download the ad. Check my example:
import UIKit
import MediaPlayer
import iAd
class ViewController: UIViewController {
// Create our MPMoviePlayerController
var moviePlayer = MPMoviePlayerController()
override func viewDidLoad() {
super.viewDidLoad()
// Preload ad
MPMoviePlayerController.preparePrerollAds()
// Setup our MPMoviePlayerController
moviePlayer.view.frame = self.view.bounds
moviePlayer.setFullscreen(true, animated: true)
}
#IBAction func playVideoButton(sender: AnyObject) {
// Add our MPMoviePlayerController to our view
self.view.addSubview(moviePlayer.view)
// Path of video you want to play
let videoURL = NSBundle.mainBundle().URLForResource("videoName", withExtension:"MOV")
// Set the contents of our MPMoviePlayerController to our video path
moviePlayer.contentURL = videoURL
// Prepare our movie for playback
moviePlayer.prepareToPlay()
// Play our video with a prerolled ad
moviePlayer.playPrerollAdWithCompletionHandler { (error) -> Void in
if (error) != nil {
NSLog("\(error)")
}
self.moviePlayer.play()
}
}
Tapping the UIButton playVideoButton a few seconds after application launch will play the prerolled video advertisement and then the desired video.
Also, If you're testing on your device go to Settings>Developer>Fill Rate> and make sure it is set to 100%.
