Building a control for the iOS camera

Now that we have built the CameraView object in the Xamarin.Forms PCL, we are going to build the CustomRenderer for iOS. Jump into the Camera.iOS project and add a new folder called Renderers, and then add a new file called CameraiOS.cs and implement the following private properties:

public sealed class CameraIOS : UIView 
    { 
        #region Private Properties 
 
        private readonly string _tag; 
 
        private readonly ILogger _log; 
 
        private readonly AVCaptureVideoPreviewLayer _previewLayer; 
 
        private readonly AVCaptureSession _captureSession; 
 
        private UIView _mainView; 
 
        private AVCaptureDeviceInput _input; 
 
        private AVCaptureStillImageOutput _output; 
 
        private AVCaptureConnection _captureConnection; 
 
        private AVCaptureDevice _device; 
 
         
        private bool _cameraBusy; 
 
        private bool _cameraAvailable; 
 
        private float _cameraButtonContainerWidth...
