Pre-roll iAds video implementation

Check out my example for a working implementation of iAd video ads:

#import "ViewController.h"
@import iAd;
@import MediaPlayer;

@interface ViewController () {
    MPMoviePlayerController *moviePlayer;
}

@end

@implementation ViewController

-(void)viewDidLoad {
    [super viewDidLoad];

    // Preload ad
    [MPMoviePlayerController preparePrerollAds];

    // Create our MPMoviePlayerController
    moviePlayer =[[MPMoviePlayerController alloc]init];
    [moviePlayer.view setFrame: self.view.bounds];
    [moviePlayer setFullscreen:YES animated:YES];
}

-(IBAction)playButton:(id)sender {
    // Add MPMoviePlayerController to our view
    [self.view addSubview:moviePlayer.view];

    // Path of movie you want to play
    NSString *moviePath = [[NSBundle mainBundle] pathForResource:@"someVideo" ofType:@"MOV"];

    // Set the contents of our MPMoviePlayerController to our path
    [moviePlayer setContentURL:[NSURL fileURLWithPath:moviePath]];

    // Prepare our movie for playback
    [moviePlayer prepareToPlay];

    // Play our movie with a prerolled ad
    [moviePlayer playPrerollAdWithCompletionHandler:^(NSError *error) {
        if (error) {
            NSLog(@"%@",error);
        }
        [moviePlayer play];
    }];
}
