🌟 The most advanced Camera framework in Swift 🌟
CameraEngine is an iOS camera engine library that allows easy integration of special capture features and camera customization in your iOS app.
######Because users love to take pictures on the iPhone, billions of applications provide features related to the iPhone camera. For us iOS developers was available two methods to implement these features. The first is to use UIImagePickerController very limited interface side, and no manipulation hardware side. AVFoundation and offers plenty of opportunity for developers, this "low level" framework is hard to use.
That's why Camera Engine was born, it proposes to have much flexibility, and offers users advanced features.

Manually
- Download all the files in the CameraEngine subdirectory.
- Add the source files to your Xcode project.
- import CameraEngine
🚀 Quick start
First let's init the and start the camera session. You can call that in the viewDidLoad, or in the appDelegate.
override func viewDidLoad() {
super.viewDidLoad()
self.cameraEngine.startSession()
}
Next time to display the preview layer
override func viewDidLayoutSubviews() {
let layer = self.cameraEngine.previewLayer
layer.frame = self.view.bounds
self.view.layer.insertSublayer(layer, atIndex: 0)
self.view.layer.masksToBounds = true
}
Capture a photo
self.cameraEngine.capturePhoto { (image: UIImage?, error: NSError?) -> (Void) in
//get the picture tooked in the 👉 image
}
Capture a video
private func startRecording() {
guard let url = CameraEngineFileManager.documentPath("video.mp4") else {
return
}
self.cameraEngine.startRecordingVideo(url, blockCompletion: { (url, error) -> (Void) in
})
}
private func stopRecording() {
self.cameraEngine.stopRecordingVideo()
}
Generate animated image GIF
guard let url = CameraEngineFileManager.documentPath("animated.gif") else {
return
}
self.cameraEngine.createGif(url, frames: self.frames, delayTime: 0.1, completionGif: { (success, url) -> (Void) in
//Do some crazy stuff here
})
🔧 configurations
Camera Engine, allows you to set some parameters, such as management of flash, torch and focus. But also on the quality of the media, which also has an impact on the size of the output file.
Flash
self.cameraEngine.flashMode = .On
self.cameraEngine.flashMode = .Off
self.cameraEngine.flashMode = .Auto
Torch
self.cameraEngine.torchMode = .On
self.cameraEngine.torchMode = .Off
self.cameraEngine.torchMode = .Auto
Focus
| CameraEngine focus
--------------------------|------------------------------------------------------------ .Locked | means the lens is at a fixed position .AutoFocus | means setting this will cause the camera to focus once automatically, and then return back to Locked .ContinuousAutoFocus | means the camera will automatically refocus on the center of the frame when the scene changes
self.cameraEngine.cameraFocus = .Locked
self.cameraEngine.cameraFocus = .AutoFocus
self.cameraEngine.cameraFocus = .ContinuousAutoFocus
Camera presset Photo
self.cameraEngine.sessionPresset = .Low
self.cameraEngine.sessionPresset = .Medium
self.cameraEngine.sessionPresset = .High
...
Camera presset Video
self.cameraEngine.videoEncoderPresset = .Preset640x480
self.cameraEngine.videoEncoderPresset = .Preset960x540
self.cameraEngine.videoEncoderPresset = .Preset1280x720
self.cameraEngine.videoEncoderPresset = .Preset1920x1080
self.cameraEngine.videoEncoderPresset = .Preset3840x2160
👀 Object detection
CameraEngine can detect faces, qrcodes, or barcode. It will return all metadata on each frame, when it detects something. To exploit you whenever you want later.
Set the detection mode
self.cameraEngine.metadataDetection = .Face
self.cameraEngine.metadataDetection = .QRCode
self.cameraEngine.metadataDetection = .BareCode
self.cameraEngine.metadataDetection = .None //disable the detection
exploiting face detection
self.cameraEngine.blockCompletionFaceDetection = { faceObject in
let frameFace = (faceObject as AVMetadataObject).bounds
self.displayLayerDetection(frame: frameFace)
}
exploiting code detection (barecode and QRCode)
self.cameraEngine.blockCompletionCodeDetection = { codeObject in
let valueCode = codeObject.stringValue
let frameCode = (codeObject as AVMetadataObject).bounds
self.displayLayerDetection(frame: frameCode)
}
🚗💨 Example
You will find a sample project, which implements all the features of CameraEngine, with an interface that allows you to test and play with the settings.
To run the example projet, run cocoapod install
, because it uses the current prod version of CameraEngine.
