我试过 NSZombie 但找不到任何东西。我将感谢您的帮助。
当我在 viewDidLoad() 中评论以下行时，没有崩溃
localAudioTrack = peerConnectionFactory.audioTrack(withTrackId: uuid!)
mediaStream = peerConnectionFactory.mediaStream(withStreamId: LOCAL_MEDIA_STREAM_ID)
mediaStream.addAudioTrack(localAudioTrack)
这里是这些变量的声明
private var mediaStream: RTCMediaStream!
private var localAudioTrack: RTCAudioTrack!
private var dataChannel: RTCDataChannel!
最佳答案
尝试使 mediaStream 和 localAudioTrack 变量变弱。这将创建指向它们的弱指针，如果没有对象再引用它们，它们就会从堆栈中释放。同样 weak 将使它们一旦被释放就可能变为 nil。
关于ios - 在 WebRTC 库中关闭 View Controller 时因 EXC_BAD_ACCESS 错误而崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47650092/
