symbol stub 我试过NSZombie，但找不到任何东西。 我会感谢你的帮助。
当我在viewDidLoad（）中注释下面的行时，没有崩溃
localAudioTrack = peerConnectionFactory.audioTrack(withTrackId: uuid!) mediaStream = peerConnectionFactory.mediaStream(withStreamId: LOCAL_MEDIA_STREAM_ID) mediaStream.addAudioTrack(localAudioTrack)
这是这些variables的声明
private var mediaStream: RTCMediaStream! private var localAudioTrack: RTCAudioTrack! private var dataChannel: RTCDataChannel!
尝试使mediaStream和localAudioTrackvariables变弱。 这将创build弱指针，如果没有对象指向它们，它们将从堆栈中释放。 弱也会使它们一旦释放就成为零。
