Installation

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

pod 'FaceCropImageView'

To run the example project, clone the repo, and run pod install from the Example directory first.

Usage

Simple usage likes below.

let myImage = UIImage(named: "some-image")
imageView.setFaceImage(imageUrl)

You can also crop the image of the web through the image URL. (In this case, the Kingfisher library is used)

let imageUrl = URL(string: "https://some-url/image.jpg")
imageView.setFaceImage(with: imageUrl)

If you need to detect faces more specifically, use fast parameter. This parameter can determine the value of CIDectorAccuracy to CIDectorAccuracyLow or CIDectorAccuracyHigh.

imageView.setFaceImage(with: imageUrl, fast: false)

And it supports the completion closure.

imageView.setFaceImage(with: imageUrl, fast: false) { result in
    switch result {
    case .success(let features):
        // `feature` means detected face infomation.
        // `features.count == 0` means no face in the image.
        print(features)
    case .failure(let error):
        print(error)
    }
}
