我有一个圆形框架UIImageView并且我需要为UIImagePickerController添加一个圆形框架裁剪工具,在从照片库中选择图像之后。与Instagram的作物成分非常相似。如何添加此类组件?
更新
我找到了这个带有圆形裁剪工具的回购协议https://github.com/ruslanskorb/RSKImageCropper
但是,在用户从照片库中选择照片后,有人能指导我如何使用UIImagePickerController实现这个裁剪工具吗?

我在调试器中收到以下消息:

我的裁剪视图中的按钮被禁用,这意味着我无法选择它们。。调试器传递给我的是什么消息?
这是我的代码:

  @IBAction func chooseProfilePicture(sender: AnyObject) {

        var myPickerController = UIImagePickerController()
        myPickerController = UIImagePickerController()
        myPickerController.delegate = self;
        myPickerController.sourceType = UIImagePickerControllerSourceType.PhotoLibrary

        self.presentViewController(myPickerController, animated: true, completion: nil)
    }

    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {

        var image : UIImage = (info[UIImagePickerControllerOriginalImage] as? UIImage)!

        editProfilePictureImageView.image = image

        self.dismissViewControllerAnimated(false, completion: { () -> Void in

            var imageCropVC : RSKImageCropViewController!

            imageCropVC = RSKImageCropViewController(image: image, cropMode: RSKImageCropMode.Circle)

            imageCropVC.delegate = self

            self.navigationController?.pushViewController(imageCropVC, animated: true)

        })

    }

最佳答案

Example Demo
是的,您可以在RSKImageCropper中添加UIImagePickerController
定义imagePicker

var imagePicker : UIImagePickerController!

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

委托方式:
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject])
{

    var image : UIImage = (info[UIImagePickerControllerOriginalImage] as? UIImage)!

    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)

    })

}
