Camera Manager

This is a simple Swift class to provide all the configurations you need to create custom camera view in your app. It follows orientation change and updates UI accordingly, supports front and rear camera selection, pinch to zoom, tap to focus, different flash modes, inputs and outputs. Just drag, drop and use.

Now it's compatible with latest Swift syntax, so if you're using any Swift version prior to 4.0 make sure to use one of the previously tagged releases.

Installation with CocoaPods

The easiest way to install the CameraManager is with: CocoaPods

Podfile

If you want Swift 4.0 syntax use:

use_frameworks!

pod 'CameraManager', '~> 4.0'

If you want Swift 3.0 syntax use:

use_frameworks!

pod 'CameraManager', '~> 3.2'

If you want Swift 2.0 syntax use:

use_frameworks!

pod 'CameraManager', '~> 2.2'

If you want Swift 1.2 syntax use:

use_frameworks!

pod 'CameraManager', '~> 1.0.14'

Installation with Swift Package Manager

The Swift Package Manager is a tool for managing the distribution of Swift code.

Add CameraManager as a dependency in your Package.swift file:

import PackageDescription

let package = Package(
    dependencies: [
        .Package(url: "https://github.com/imaginary-cloud/CameraManager", majorVersion: 4, minor: 0)
    ]
)

Installation with Carthage

Carthage is another dependency management tool written in Swift.

Add the following line to your Cartfile:

If you want Swift 4.0 syntax use:

github "imaginary-cloud/CameraManager" >= 4.0

If you want Swift 3.0 syntax use:

github "imaginary-cloud/CameraManager" >= 3.2

If you want Swift 2.0 syntax use:

github "imaginary-cloud/CameraManager" >= 2.2

If you want Swift 1.2 syntax use:

github "imaginary-cloud/CameraManager" >= 1.0

And run carthage update to build the dynamic framework.

How to use

To use it you just add the preview layer to your desired view, you'll get back the state of the camera if it's unavailable, ready or the user denied access to it. Have in mind that in order to retain the AVCaptureSession you will need to retain cameraManager instance somewhere, ex. as an instance constant.

let cameraManager = CameraManager()
cameraManager.addPreviewLayerToView(self.cameraView)

You can set input device to front or back camera:

cameraManager.cameraDevice = .Front
cameraManager.cameraDevice = .Back

You can specify if the front camera image should be horizontally fliped:

cameraManager.shouldFlipFrontCameraImage = true

You can enable or disable gestures on camera preview:

cameraManager.shouldEnableTapToFocus = true
cameraManager.shouldEnablePinchToZoom = true

You can set output format to Image, video or video with audio:

cameraManager.cameraOutputMode = .StillImage
cameraManager.cameraOutputMode = .VideoWithMic
cameraManager.cameraOutputMode = .VideoOnly

You can set the quality:

cameraManager.cameraOutputQuality = .Low
cameraManager.cameraOutputQuality = .Medium
cameraManager.cameraOutputQuality = .High

You can specifiy the focus and exposure mode:

cameraManager.focusMode = .continuousAutoFocus 
cameraManager.exposureMode = .continuousAutoExposure 

You can change the flash mode (it will also set corresponding flash mode):

cameraManager.flashMode = .Off
cameraManager.flashMode = .On
cameraManager.flashMode = .Auto

To enable location services for storing in Camera Roll. Default is false:

cameraManager.shouldUseLocationServices = true

To check if the device supports flash call:

cameraManager.hasFlash

To change flash mode to the next available one you can use this handy function which will also return current value for you to update the UI accordingly:

cameraManager.changeFlashMode()

You can specify if you want to save the files to phone library:

cameraManager.writeFilesToPhoneLibrary = true

You can specify if you want to disable animations:

cameraManager.animateShutter = false
cameraManager.animateCameraDeviceChange = false

You can specify if you want the user to be asked about camera permissions automatically when you first try to use the camera or manually:

cameraManager.showAccessPermissionPopupAutomatically = false

You can even setUp your custom block to handle error messages: It can be customized to be presented on the Window root view controller, for example.

cameraManager.showErrorBlock = { (erTitle: String, erMessage: String) -> Void in
    var alertController = UIAlertController(title: erTitle, message: erMessage, preferredStyle: .Alert)
    alertController.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: { (alertAction) -> Void in
    }))

    let topController = UIApplication.sharedApplication().keyWindow?.rootViewController

    if (topController != nil) {
        topController?.presentViewController(alertController, animated: true, completion: { () -> Void in
            //
        })
    }

}

To shoot image all you need to do is call:

cameraManager.capturePictureWithCompletion({ (image, error) -> Void in
	self.myImage = image             
})

To record video you do:

cameraManager.startRecordingVideo()
cameraManager.stopVideoRecording({ (videoURL, error) -> Void in
	NSFileManager.defaultManager().copyItemAtURL(videoURL, toURL: self.myVideoURL, error: &error)
})

Support

Supports iOS 8 and above. Xcode 9.0 is required to build the latest code written in Swift 4.0.
