CameraPreviewController

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.

front camera preview / still capture / video capture
back camera preview / still capture / video capture
flipping camera
torch control
tap to focus
add/remove filter
face detection
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
}
