License

FilterCam is available under the MIT license. See the LICENSE file for more info.

Installation

Carthage:

Add this to Cartfile

github "nkmrh/FilterCam"
$ carthage update FilterCam

Cocoapods:

FilterCam is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "FilterCam"

Manual Installation:

Simply copy the contents of the FilterCam folder into your project.

Usage

Using FilterCam is very simple.

Prerequisites:

As of iOS 10, Apple requires the additon of the NSCameraUsageDescription and NSMicrophoneUsageDescription strings to the info.plist of your application. Example:

<key>NSCameraUsageDescription</key>
    <string>To record video</string>
<key>NSMicrophoneUsageDescription</key>
    <string>To record audio with video</string>

Getting Started:

If you install FilterCam from Cocoapods, be sure to import the module into your View Controller:

import FilterCam

FilterCam is a drop-in convenience framework. To create a Camera instance, create a new UIViewController subclass. Replace the UIViewController subclass declaration with FilterCamViewController:

class MyCameraViewController : FilterCamViewController

That is all that is required to setup the AVSession for photo and video capture. FilterCam will prompt the user for permission to use the camera/microphone, and configure both the device inputs and outputs.

Capture

Capturing Video is just as easy. To begin recording video, call the startRecording function:

startRecording()

To end the capture of a video, call the stopRecording function:

stopRecording()

Delegate

You must implement the FilterCamViewControllerDelegate and set the cameraDelegate to your view controller instance:

class MyCameraViewController : FilterCamViewController, FilterCamViewControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
        cameraDelegate = self
    }
    ...
}

Delegate methods:


func filterCamDidStartRecording(_ filterCam: FilterCamViewController) {
    // Called when startRecording() is called
}

func filterCamDidFinishRecording(_ filterCame: FilterCamViewController) {
    // Called when stopRecording() is called
}

func filterCam(_ filterCam: FilterCamViewController, didFinishWriting outputURL: URL) {
    // Called when stopRecording() is called and the video is finished processing
    // Returns a URL in the temporary directory where video is stored
}

func filterCam(_ filterCam: FilterCamViewController, didFocusAtPoint tapPoint: CGPoint) {
    // Called when a user initiates a tap gesture on the preview layer
    // Returns a CGPoint of the tap location on the preview layer
}

func filterCam(_ filterCam: FilterCamViewController, didFailToRecord error: Error) {
    // Called when recorder fail to record
}

Torch

The torch can be enabled by changing the torchLevel property:

torchLevel = 1

Torch level specifies the value between 0.0 and 1.0.

Switching Camera

By default, FilterCam will launch to the rear facing camera. This can be changed by changing the defaultCamera property in viewDidLoad:

devicePosition = .front

Configuration

Apply filter

You can apply custom filters by specifying an array of filters in the filters property:

filters = [CIFilter(name: "CIPhotoEffectInstant")!, CIFilter(name: "CIPhotoEffectNoir")!]

filters property type is an array of CIFilter. It is applied sequentially from the first filter.

Preview view

If you want to specify the preview frame, you can use custom initializer:

MyCameraViewController(previewViewRect: CGRect)

Video Quality

Video quality can be set by the videoQuality property of FilterCamViewController. The choices available AVCaptureSessionPreset.
