iOS流式背景音频

Question

以下是找到音频流的有效代码：

    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:stringURL]];
    [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
    connectionPlay = [[NSURLConnection alloc] initWithRequest:request delegate:self];
    NSError *playerError;
    player = [[AVAudioPlayer alloc] initWithData:streamData error:&playerError];
    player.numberOfLoops = 0;
    player.volume = 1.0f;
    [player prepareToPlay];

    if (playerError) {
        NSLog(@"audio player error: %@", [playerError localizedDescription]);
    }
    if (player == nil)
        NSLog(@"%@", [playerError description]);
    else
        [player play];

当我尝试使应用进入后台模式时，我会抓住机会玩。 我进入.plist并进入必填背景模式，项目0，应用播放音频。 这没有解决我的问题。

我开始放置这个：

[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback
                                       error:nil];
[[AVAudioSession sharedInstance] setActive:YES
                                     error:nil];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];

代替

- (void)applicationWillResignActive:(UIApplication *)application

- (void)applicationDidEnterBackground:(UIApplication *)application

和

在主ViewController的viewDidLoad内部。 以及在[player prepareToPlay]之后。

我不确定问题是否出在我设置的背景设置不正确或应用程序断开了连接。 基本上，我不确定我缺少什么。

我一直在看：

编辑：有人吗？

Answer 1

我不知道它是什么，但是我只是将所有代码转移到一个新项目中，添加了此代码

 - (void)applicationWillResignActive:(UIApplication *)application
{

    [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback
                                           error:nil];
    [[AVAudioSession sharedInstance] setActive:YES
                                         error:nil];
    [[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
    // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}

和plist设置，似乎可以在手机上使用，但不能在模拟器上使用。
