Example

To run the example project, clone the repo, and run pod install from the Example directory first.

I’m writing this since I couldn’t find a open source with complete basic source to start develop camera application from, and is based on GPUImage library inside.

This example contains the following features.

1) front camera preview / still capture / video capture

2) back camera preview / still capture / video capture

3) flipping camera

4) torch control

5) tap to focus

6) add/remove filter

7) face detection

8) pinch to zoom in/out

I’m going to add more features that every camera application must have.

Please don’t hesitate to contribute on this project. Any advice and suggestions will be greatly appreciated.

Functions

  • To take photo,
takePhoto({ image in
    let photoVC = PhotoViewController()
    photoVC.image = image
    self.present(photoVC, animated: true, completion: nil)
})
  • To take video,
// to start
startRecordingVideo()

// to finish
finishRecordingVideo()

// to handle success
extension ViewController: CameraPreviewControllerDelegate {
    func cameraPreview(_ controller: CameraPreviewController, didSaveVideoAt url: URL) {
        // which is file url in temporary directory
    }
    func cameraPreview(_ controller: CameraPreviewController, didFailSaveVideoWithError error: Error) {
    }
    ...
}
  • To change camera,
flipCamera()
switch cameraPosition {
    // do something
}
  • To control torch,
torchMode = .on
torchMode = .off
torchMode = .auto
  • To add, remove filters
add(filter: filter)
removeFilters()
  • To detect face,
// set true somewhere
isFaceDetectorEnabled = true

// handle result
func cameraPreview(_ controller: CameraPreviewController, detected faceFeatures: [CIFaceFeature]?, aperture: CGRect, orientation: UIDeviceOrientation) {
    guard let faces = faceFeatures, faces.count > 0 else {
        return
    }
    // do something
