## 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,
```Swift
takePhoto({ image in
let photoVC = PhotoViewController()
photoVC.image = image
self.present(photoVC, animated: true, completion: nil)
})
```
- To take video,
```Swift
// 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,
```Swift
flipCamera()
switch cameraPosition {
// do something
}
```
- To control torch,
```Swift
torchMode = .on
torchMode = .off
torchMode = .auto
```
- To add, remove filters
```Swift
add(filter: filter)
removeFilters()
```
- To detect face,
```Swift
// 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
}
```
