Stop AVCaptureSession when leaving ViewController

Question

I have ViewController with AVCaptureSession. I can start and stop AVCaptureSession easily :

var captureSession: AVCaptureSession?
captureSession = AVCaptureSession()

//start
captureSession?.startRunning() 

//stop
captureSession?.stopRunning()

A want to know how can I stop AVCaptureSession when user opens another ViewController.

In `viewWillDisappear` for example? – Larme May 23 '16 at 15:30 — Larme, May 23 '16 at 15:30

Just have the viewWillDisappear method handle that for you.

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