What is AvatarCapture?

Writing a ground-up solution for taking profile pictures in iOS can be a pain and time consuming. AvatarCapture is a Swift based library inspired by ZCSAvatarCapture whose purpose is to make it as easy as possible to start your camera(front facing or rear), allow you to snap a photo or choose a photo from your Photos library.

Installation

Note: AvatarCapture has a minimum deployment target of iOS 10

Edit your PodFile:
pod 'AvatarCapture'

Then run pod install

Features

• Display an existing UIImage
• Start the iPhone camera for capture
• Swap cameras from front facing to rear and vice versa
• Choose a photo from the iPhone library

Plans

• allow more flexibility in where buttons are positioned
• add custom elements/subviews
• Change/choose shape of avatar profile

Getting Started

Getting started with AvatarCapture is super easy!

First, initialize the view controller(anywhere but viewDidLoad is common):

 let avatarCaptureController = AvatarCaptureController()
 avatarCaptureController.delegate = self
 avatarCaptureController.image = UIImage.init(named: "an_existing_image.png")
 avatarView.addSubview((avatarCaptureController?.view)!)

AvatarCaptureController subscribes to AvatarCaptureControllerDelegate and is required for retrieving the UIImage after selecting a photo

In this example, avatarView is a UIView defined in a storyboard. Whatever the width and height of this UIView is will determine the dimensions of the avatar.

Helper Methods

startCapture() - Begins capturing the output from your iPhone camera and displays the on screen buttons to interact with your camera
endCapture() - Stops the live preview of the iPhone camera. This method does not need to be explicitly called in most situations
swapCameras() - Swaps the live preview from the front to rear camera and vice versa. This method does not need to be explicitly called in most situations.
showImagePicker() - Displays the Photos library for choosing an image

How do I get my image?

Once you've subscribed to the AvatarCaptureControllerDelegate protocol, you can be notified when an image was selected and when the image selection was cancelled:

extension MyViewController: AvatarCaptureControllerDelegate {
    func imageSelected(image: UIImage) {
        print("image Selected")
    }
    
    func imageSelectionCancelled() {
        print("image selection cancelled")
    }
}

AvatarCapture In Action

Don't I look excited...?
