Question

我正在尝试在swift 3中为iOS 10.1设置自定义相机。

我一直收到

下面的错误消息

“[MC]系统组容器 systemgroup.com.apple.configurationprofiles路径是 /private/var/containers/Shared/SystemGroup/systemgroup.com.apple.configurationprofiles 从公共有效用户设置中读取。 “

我尝试将“隐私 - 相机使用说明”添加到info.plist和麦克风中，但仍有问题。

有时当我从代码中断开我的iPhone时，会发出授权相机的消息，就好像它被“卡住”和“停止”一样？

有没有人知道如何使用AVCaptureStillImageOutput？它在iOS 10以后已被弃用，我想让我的应用程序在未来有点防弹。

解决了这个问题！

以下正确代码：

    override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    // setting up the camera session
    captureSession = AVCaptureSession()
    captureSession?.sessionPreset = AVCaptureSessionPreset1920x1080
    let deviceDiscoverySession = AVCaptureDeviceDiscoverySession(deviceTypes: [AVCaptureDeviceType.builtInDuoCamera, AVCaptureDeviceType.builtInTelephotoCamera,AVCaptureDeviceType.builtInWideAngleCamera], mediaType: AVMediaTypeVideo, position: AVCaptureDevicePosition.front)
    for device in (deviceDiscoverySession?.devices)! {
        if device.position == AVCaptureDevicePosition.front{
            do {
                let input = try AVCaptureDeviceInput(device: device)
                if (captureSession?.canAddInput(input))!{
                    captureSession?.addInput(input)
                    stillImageOutput = AVCaptureStillImageOutput()
                    stillImageOutput?.outputSettings = [AVVideoCodecKey:AVVideoCodecJPEG]
                if (captureSession?.canAddOutput(stillImageOutput))! {
                    captureSession?.addOutput(stillImageOutput)
                    previewLayer = AVCaptureVideoPreviewLayer(session: captureSession)
                    previewLayer?.videoGravity = AVLayerVideoGravityResizeAspect
                    previewLayer?.connection.videoOrientation = AVCaptureVideoOrientation.portrait
                    cameraView.layer.addSublayer(previewLayer!)
                    captureSession?.startRunning()
                    }
                }
            } catch{
                print("Error Occured when trying get camera")
            }
        }
    }
}

AVCaptureSession Swift 3糟糕的exec问题？
