AVPlayerはシミュレータ上で動作しますが、デバイス上にはありません

Question

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

これはシミュレータ上で動作していますが、デバイス内で動作しています。コンソールでは、 は、私は次のエラーを持っている：

CredStore - performQuery - Error copying matching creds. Error=-25300, query={ class = inet; "m_Limit" = "m_LimitAll"; "r_Attributes" = 1; sync = syna; }

誰もが手掛かりで私を助けることができますか？

    [[AVAudioSession sharedInstance] setActive:YES withOptions:AVAudioSessionSetActiveOptionNotifyOthersOnDeactivation error:&activationError]; 
    [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback withOptions:AVAudioSessionCategoryOptionAllowBluetooth error:&setCategoryError];
