ios - 离开ViewController时停止AVCaptureSession

我有带AVCaptureSession的ViewController。我可以轻松启动和停止AVCaptureSession:

var captureSession: AVCaptureSession?
captureSession = AVCaptureSession()

//start
captureSession?.startRunning()

//stop
captureSession?.stopRunning()

想知道当用户打开另一个ViewController时如何停止AVCaptureSession。

最佳答案

只需让viewWillDisappear方法为您处理即可。

override func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(animated)
    captureSession?.stopRunning()
}
