Easy, and quick library for handling iOS camera.

Installation

You can download the latest framework files from our Release page.
P9CameraManager also available through CocoaPods. To install it simply add the following line to your Podfile.
pod ‘P9CameraManager’

Play

You can choose starting mode to capture photo or video.

Start preview to taking photo like this,

P9CameraManager.shared().startWithPreviewView(forPhoto: cameraView)

and, video.

P9CameraManager.shared().startWithPreviewView(forVideo: cameraView, enableAudio: false)

or, choose start for custom setting and preset you want.

P9CameraManager.shared().start(withPreviewView: cameraView, preset: AVCaptureSessionPreset3840x2160, enableVideo: true, enableAudio: false)

Now, Take a picture.

P9CameraManager.shared().captureStillImage { (status:P9CameraManagerStatus, image:UIImage?, fileUrl:URL?) in
    if let image = image {
        // do something you want.
    }
}

Another way to take a picture. It provide smaller image then captureStillImage but no shutter sound.

P9CameraManager.shared().capturePreviewImage { (status:P9CameraManagerStatus, image:UIImage?, fileUrl:URL?) in
    if let image = image {
        // do something you want.
    }
}

And, recoding video like this.

P9CameraManager.shared().recordVideo(toFileUrl: url)

Stop recording.

P9CameraManager.shared().stopRecordingVideo({ (status, image, fileUrl) in
    if let fileUrl = fileUrl {
        // do something you want.
    }
}

You can handle every all frame images by setting preview handler.

P9CameraManager.shared().setPreviewHandler { (sampleBuffer) in
    let request = VNCoreMLRequest(model: model) { (finishedRequest, error) in
        if let result = finishedRequest.results as? [VNClassificationObservation] {
            let descriptions = result.prefix(2).map { classification in
                return String(format: "%@ (%.2f)", classification.identifier, classification.confidence)
            }
            DispatchQueue.main.async {
                self.desciptionLabel.text = descriptions.joined(seprator: "n")
            }
        }
    }
    request.imageCropAndScaleOption = .centerCrop
    if let sampleBuffer = sampleBuffer, let imageBuffer = CMSampleBufferGetImageBuffer(sampleBuffer) {
        try? VNImageRequestHandler(cvPixelBuffer: imageBuffer, options: [:]).perform([request])
    }
}

Utility functions help you to reprocess image or video.
You can resizing media by given width, height with keep rate, custom resizing, crop center square and so on for captured image or video by utility function.

P9CameraManager.shared().captureStillImage { (status:P9CameraManagerStatus, image:UIImage?, fileUrl:URL?) in
    if let image = image {
        P9CameraManager.processingImage(image, type: .cropCenterSquare, referenceSize: .zero, completion: { (status, image, fileUrl) in
            if let image = image {
                // do something you want.
            }
        })
    }
}

P9CameraManager.shared().stopRecordingVideo({ (status, image, fileUrl) in
    if let fileUrl = fileUrl {
        P9CameraManager.processingVideo(fileUrl, toOutputFileUrl: outputFileUrl, type: .cropCenterSquare, referenceSize: .zero, preset: AVAssetExportPresetHighestQuality, completion: { (status, image, fileUrl) in
            if let fileUrl = fileUrl {
                // do something you want.
            }
        })
    }
}

Observe P9CameraManager event to deal with business logic.

NotificationCenter.default.addObserver(self, selector:#selector(cameraManagerReport), name:NSNotification.Name(rawValue: P9CameraManagerNotification), object:nil)

For example, you can get every frame of previewing image.

@objc func cameraManagerReport(notification:NSNotification) {
    guard let userInfo = notification.userInfo, let status = P9CameraManagerStatus(rawValue: userInfo[P9CameraManagerNotifyParameterKeyStatus] as? Int ?? 0) else {
        return
    }
    if status == .previewImageCaptured, let image = userInfo[P9CameraManagerNotifyParameterKeyImage] as? UIImage {
        // do something you want.
    }
}

You can do all things with changing camera device position, video orientation, preview mode.
