SwiftCommon project includes something that can be reused in the future.
It's easy to use this cropper, you implement the protocol SCImageCropperDelegate first and then push or present the cropper view controller.
Implement the SCImageCropperDelegate to handle the results:
protocol SCImageCropperDelegate {
func imageCropper(cropper: SCImageCropperViewController, didFinishCroppedWithImage resultImage: UIImage)
func imageCropperDidCancel(cropper: SCImageCropperViewController)
}
Push or present the cropper view controller after getting a image:
let cropperVC = SCImageCropperViewController(image: image, cropSize: CGSize(width: self.view.frame.size.width, height: self.view.frame.size.width))
cropperVC.delegate = self
self.navigationController?.pushViewController(cropperVC, animated: true)
