【问题描述】：

嗯，我想在 MPMoviePlayer 中开始播放视频之前展示视频广告

这就是我正在做的：-

    moviePlayer = [MPMoviePlayerController new];

    moviePlayer.contentURL = [NSURL URLWithString:@"http://xyz/xyz.m3u8"];

    [moviePlayer playPrerollAdWithCompletionHandler:^(NSError *error) {
            // Check if error is non-nil during development
            [moviePlayer play];
        }];
    moviePlayer.view.frame=CGRectMake(0, 20, 300, self.view.frame.size.width);
    [self.view addSubview:moviePlayer.view];
    [self.view layoutIfNeeded];

在 Appdelegate.m 中

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.

    [MPMoviePlayerController preparePrerollAds];
    return YES;
}

但我还应该做些什么来展示广告视频或如何配置 iAD 以让应用了解将哪个特定视频作为广告播放。

目前该应用只是播放此网址“http://xyz/xyz.m3u8”的视频，但没有显示任何广告。

【解决方案1】：

在调用playPrerollAdWithCompletionHandler 之前，您需要先prepareToPlay 您的MPMoviePlayerController，然后在play 之前将您的MPMoviePlayerController 添加到您的view。此外，您可能在[MPMoviePlayerController preparePrerollAds] 有机会完全下载视频广告之前播放视频。检查我的例子：

#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) {
        [moviePlayer play];
    }];
}
