Add a circular cropping component for UIImagePicker?

Question

I Have a circular framed UIImageView and I need to add a circular framed cropping tool for the UIImagePickerController, after the image is selected

Answer 1

For Swift 2.2:

add delegate methods to your class:

class ViewController: UIViewController, UIImagePickerControllerDelegate, RSKImageCropViewControllerDelegate, UINavigationControllerDelegate 

define imagePicker

    var imagePicker : UIImagePickerController!

in viewDidLoad()

imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
self.presentViewController(imagePicker, animated: true, completion: nil)

And delegate methode :

func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!) {

    let image : UIImage = image
    picker.dismissViewControllerAnimated(false, completion: { () -> Void in
        var imageCropVC : RSKImageCropViewController!
        imageCropVC = RSKImageCropViewController(image: image, cropMode: RSKImageCropMode.Circle)
        imageCropVC.delegate = self
        self.navigationController?.pushViewController(imageCropVC, animated: true)  
    })  
}

Of course it need to do bridge for objective C class

Oh, link to RSKImageCrop
