Demo :

---

Installation :

CocoaPods :

pod 'MFCameraManager'

or download CustomCameraManagerClass directory and add it manually to your project

Setup :

Now in your view add a UIView to storyboard view controller or programmetically initiate an UIView which will be your camera preview. then follow steps to display the camera :

If you just need the camera session and capturing image you have to use CameraManager.swift class, as it has StillImageOutput.

but if you need the camera session to scan barcode beside capturing image you have to use ScanBarcodeCameraManager.swift class, as it has StillImageOutput.

initial step

Create a variable of which class you prefer (ScanBarcodeCameraManager.swift or CameraManager.swift) :

var cameraManager = CameraManager()

or

var cameraManager = ScanBarcodeCameraManager()

from now on below 4 steps are similar in each class you instantiated :

1 - on your viewDidLoad setup the camera with your UIView created to show the camera preview inside it, and your camera position which its default is back :

cameraManager.captureSetup(in: self.cameraView, with: .back)

2 - in viewWillApear delegate call this method :

cameraManager.startRunning()

3 - in viewDidDisapear delegate call below method :

cameraManager.stopRunning()

4 - to support landscape transitions add below code to viewWillTransition Delegate :

cameraManager.transitionCamera()

Features in CameraManager class

• to capture an image showing on camera :

self.cameraManager.getcroppedImage { (UIImage, error) in

          //your code here to handle with error or if error == nil , get the UIImage 
}

• to get the image inside a frame or CGRect , give the frame as a params to getcroppedImage function like below :

self.cameraManager.getcroppedImage(with: self.rectLayer.frame) {  (UIImage, error) in
         
       //your code here to handle with error or if error == nil , get the UIImage 
           
 }

Features in ScanBarcodeCameraManager class

• to get the scanned barcode and capture an image :

should conform to protocol ScanBarcodeCameraManagerDelegate and :

self.cameraManager.delegate = self

then implement the function to get the barcode objects and also the captured image :

func scanBarcodeCameraManagerDidRecognizeBarcode(barcode: Array<AVMetadataMachineReadableCodeObject>, image: UIImage?) {
        self.scanBarcodeCameraManager.stopRunning()
        print(barcode)
        // to whatever you like to the barcode objects and the image
        scanBarcodeCameraManager.startRunning()

    }

Extra features in all classess

• to enable torch mode use below code with level of torch mode default is 1 :

cameraManager.enableTorchMode(level: 1)
