ios - 使用playPrerollAdWithCompletionHandler方法通过MPMoviePlayerController实现iAd视频

Question

好吧，我想在MPMoviePlayer中开始播放视频之前展示一个视频广告

这就是我在做什么:-

    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];

并在Appdelegate.m中

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

    [MPMoviePlayerController preparePrerollAds];
    return YES;
}

但是，我应该做些什么才能显示广告视频，或者如何配置iAD以使该应用了解将哪个特定视频作为广告播放。

目前，该应用程序仅播放此网址“ http://xyz/xyz.m3u8”视频，但未展示任何广告。

在调用prepareToPlay之前，您需要先对MPMoviePlayerController进行playPrerollAdWithCompletionHandler编码，然后在对MPMoviePlayerController进行编码之前，将view添加到play中。另外，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];
    }];
}
