如何在相机应用程序中添加裁剪功能

Question

我已经实现了从图库中挑选图像或拍照，并且我正在屏幕的 uiimage 视图中显示。但我想实现裁剪功能。

意味着，在我从手机拍照后，我需要裁剪，然后我需要显示在我的屏幕上。怎么办？？

这是我的代码：

var imagePicker: UIImagePickerController!

@IBOutlet weak var imagevView: UIImageView!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}



@IBAction func ChooseImage(_ sender: AnyObject) {

    imagePicker =  UIImagePickerController()
    imagePicker.delegate = self
    imagePicker.sourceType = .camera


    present(imagePicker, animated: true, completion: nil)

}


func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    imagePicker.dismiss(animated: true, completion: nil)
    imagevView.image = info[UIImagePickerControllerOriginalImage] as? UIImage

        }

谢谢

您可以在某种程度上使用imagePicker.allowsEditing = true 设置。如果您想要更高级的裁剪，比如@Kamlesh 建议的内容，您可能正在寻找。
