# SwiftyCam
[![Version](https://img.shields.io/cocoapods/v/SwiftyCam.svg?style=flat)](http://cocoapods.org/pods/SwiftyCam)
[![License](https://img.shields.io/cocoapods/l/SwiftyCam.svg?style=flat)](http://cocoapods.org/pods/SwiftyCam)
[![Platform](https://img.shields.io/cocoapods/p/SwiftyCam.svg?style=flat)](http://cocoapods.org/pods/SwiftyCam)
## Overview
SwiftyCam is a a simple, clean iOS Camera framework for easy photo and video capture. SwiftyCam allows users to capture both photos and videos from the same session with very little configuration.
Configuring a Camera View Controller in AVFoundation can be tedious and time consuming. SwiftyCam is a drop in View Controller which gives complete control of the AVSession.
## Requirements
* iOS 8.0+
* Swift 3.0+
## License
SwiftyCam is available under the BSD license. See the LICENSE file for more info.
## Installation
### Cocoapods:
SwiftyCam is available through [CocoaPods](http://cocoapods.org). To install
it, simply add the following line to your Podfile:
```ruby
pod "SwiftyCam"
```
### Manual Installation:
Simply copy the contents of the Source folder into your project.
## Usage
Using SwiftyCam 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 Take Photos and Video</string>
<key>NSMicrophoneUsageDescription</key>
<string>To Record Audio With Video</string>
### Getting Started:
Add the import statement to the View Controller you ware working in:
import SwiftyCam
SwiftyCam is a drop-in convenience framework. To create a Camera instance, create a new UIViewController subclass. Replace the UIViewController subclass declaration with SwiftyCamViewController:
class MyCameraViewController : SwiftyCamViewController
That is all that is required to setup the AVSession for photo and video capture. SwiftyCam will prompt the user for permission to use the camera/microphone, and configure both the device inputs and outputs.
## Capture
### SwiftyCamButton:
SwiftyCam comes with a very convenient method of capturing media. SwiftyCamButton uses gesture recognizers to take either photos of videos.
A single tap of the SwiftyCam button triggers a photo capture.
A long press/tap and hold gesture initiates a video capture. Releasing the button ends the video recoring.
To use a SwiftyCamButton, simply create one and assign the delegate to your SwiftyCamViewController:
let captureButton = SwiftyCamButton(frame: buttonFrame)
captureButton.delegate = self
### Manual:
Capturing media with SwiftyCam is very simple. To capture a photo, simply call the takePhoto function:
takePhoto()
Capturing Video is just as easy. To begin recording video, call the startVideoRecording function:
startVideoRecording()
To end the capture of a video, call the endVideoRecordingFunction:
endVideoRecording()
###Delegate
In order to acquire the photos and videos taken by either the SwiftyCamButton or manually, you must implement the SwiftyCamViewControllerDelegate and set the delegate to your view controller instance:
class MyCameraViewController : SwiftyCamViewController, SwiftyCamViewControllerDelegate
and in your viewDidLoad, assign the cameraDelegate to self:
self.cameraDelegate = self
####Delegate methods:
**SwiftyCamDidTakePhoto(_ photo:UIImage)** - Return a UIImage captured from the AVSession
**SwiftyCamDidBeginRecordingVideo()** - Called when the capture session begins recording a video
**SwiftyCamDidFinishRecordingVideo()** - Called when the capture session has finished recording a video and has begun processing
**SwiftyCamDidFinishProcessingVideoAt(_ url: String)** - Called when the capture session finished processing the video returns the location on disk the video is stored. This will always be in the temorary folder of the device.
**SwiftyCamDidSwitchCameras(camera: SwiftyCamViewController.CameraSelection)** - Called when the user has initiated a switch in camera orientations.
**SwiftyCamDidFocusAtPoint(focusPoint: CGPoint)** - Returns the point on the preview where a tap to focus was initiated (Will only be called if *tapToFocus* is set to *true*)
**SwiftyCamDidChangeZoomLevel(zoomLevel: CGFloat)** - Returns the current zoom level of the preview layer after a pinch to zoom has been initiated. Will be called several times (Will only be called if *pinchToZoom* is set to *true*)
**SwiftyCamDidFailCameraPermissionSettings()** - Called during SwiftyCamViewController launch if the user has denied permission to access either the camera of microphone (Will only be called if *promptToAppPrivacySettings* is set to *false*)
## Flash
The flash(torch) can be enabled on the device by calling:
toggleFlash()
The flash will only be enabled if the current camera is the rear camera and will automatically if the camera switches or the View Controller is dismissed.
## Switching Camera
SwiftyCam supports capture from both the front and back cameras. To switch cameras, call the function:
switchCamera()
Tap-to-focus, pinch-to-zoom and camera flash are not supported when the front facing camera is selected. *Switching video while video is being recorded is not currently supported*
##Configuration
SwiftyCam has several options for configurating the functionality of the capture:
### Video Quality
Video quality can be set by the **videoQuality** property of SwiftyCamViewController. The choices available correspond to the matching **AVCaptureSessionPreset**:
* **.high** (AVCapturePresetHigh)
* **.medium** (AVCapturePresetMedium)
* **.low** (AVCapturePresetLow)
* **.resolution352x288** (AVCaptureSessionPreset352x288)
* **.resolution640x480** (AVCaptureSessionPreset640x480)
* **.resolution1280x720** (AVCaptureSessionPreset1280x720)
* **.resolution1920x1080** (AVCaptureSessionPreset1920x1080)
* **.resolution3840x2160** (AVCaptureSessionPreset3840x2160)
* **.iframe960x540** (AVCaptureSessionPresetiFrame960x540)
* **.iframe1280x720** (AVCaptureSessionPresetiFrame1280x720)
The default value is **.resolution1920x1080**
### Maximum Video Duration
If using a SwiftyCamButton, you can set a maximum video duration for the length of video. The video recording will me automatically stopped once the time limit has been reached and the delegate method **SwiftyCamDidFinishRecordingVideo** will be called. To set this value, simply change the **kMaximumVideoDuration** value:
kMaximumVideoDuration = 10.0
A value of **0.0** will allow for unlimited video recording via the SwiftyCamButton. The default value is **0.0**.
## Camera Zoom
SwiftyCam supports digital zoom of the camera session via pinch gestures. The gestures work similar to the default iOS app and will zoom to the maximum supported zoom level. Camera zoom is only supported on the rear facing camera. AVFoundation does not currently support front facing camera zoom. To disable this feature, change the **pinchToZoom** property:
pinchToZoom = false
By default, **pinchToZoom** is enabled.
## Camera Focus
SwiftyCam, by default, support tap to focus on the video preview. SwiftyCam will set the focus and exposure levels of the session to the tapped point. Autofocus and autoexposure will be resumed once SwiftyCam detects significant movement from the tapped point. To disable this feature, change the **tapToFocus** property:
tapToFocus = false
By default, **tapToFocus** is enabled. If you wish to show a on screen animation when a tap to focus is initiated, you can use the **SwiftyCamDidFocusAtPoint(focusPoint:)** to get the coordinates of tap and provide your own tap animation
## Privacy
When a user firsts launch SwiftyCamViewController, they will be prompted for permission for access to the cameras and microphones. By default, if a user declines access to the hardware, SwiftyCam will provide a prompt to the App privacy settings inside the iOS settings application. If you wish to change this behaviour, the **promptToAppPrivacySettings** property can be modified:
promptToAppPrivacySettings = false
Instead of prompting the user to the settings application, the delegate method **SwiftyCamDidFailCameraPermissionSettings** will be called and will have to be manually handled.
## Miscellaneous
Other properties:
* **isCameraFlashOn** - Bool
* **isVideoRecording** - Bool
* **isSessionRunning** - Bool
* **currentCamera** - CameraSelection
