AVPlayer在模拟器上运行，但不在设备上运行

Question

  playerItem=[AVPlayerItem playerItemWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://www.radio.com.lk/y-fm/"]]];
  player=[AVPlayer playerWithPlayerItem:playerItem] ;
  [player play];

它正在使用模拟器，但在设备中，它不是。 在控制台中，我有以下错误：

CredStore - performQuery - 复制匹配的信息时出错。 错误= -25300，query = {class = inet; “m_Limit”=“m_LimitAll”; “r_Attributes”= 1; sync = syna; }

任何人都可以帮我一个线索吗？

Answer 1

请在您的应用代表中添加以下代码。 它可能会帮助你

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [[AVAudioSession sharedInstance] setActive:YES withOptions:AVAudioSessionSetActiveOptionNotifyOthersOnDeactivation error:&activationError];
    [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback withOptions:AVAudioSessionCategoryOptionAllowBluetooth error:&setCategoryError];
    [[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
}
