ios - 单击 iPhone 中的图像后，图像选择器 Controller 无法更改默认裁剪方 block 大小

Question

image showing the imagepickercontroller

如图所示，当我从相机拍照时，该方形位置不会改变或调整大小，但它可以在图库中工作。请帮助了解如何更改裁剪方 block 的位置以转到图像的所需部分。

下面给出了使用的代码

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    if let  image = info[UIImagePickerControllerOriginalImage] as? UIImage
    {
        print(image.size)
        let croppedImage = info[UIImagePickerControllerEditedImage] as? UIImage
        print(croppedImage ?? "")
        let cropRect = (info[UIImagePickerControllerCropRect]! as AnyObject).cgRectValue
        print(cropRect?.size ?? "")
        let _ = UIImage.cropImage(image: image, toRect: CGRect.init(x: 0, y: 0, w: self.imgProfile.bounds.width, h: self.imgProfile.bounds.width))
        print(image.size)
        self.imgProfile.image = croppedImage
        profileImgUpdated = true

    }
    self.dismiss(animated: true, completion: nil)
}

func openCamera(){
    self.imagePicker.sourceType = .camera
    self.imagePicker.allowsEditing = true
    self.imagePicker.delegate = self
    self.present(imagePicker, animated: true)
}

func openPhotoLibrary() {
    self.imagePicker.sourceType = .photoLibrary
    self.imagePicker.allowsEditing = true
    self.imagePicker.delegate = self
    self.present(imagePicker, animated: true)
}

在Swift 4.2中didFinishPickingMediaWithInfo信息:[String:Any]已被废弃，请尝试使用，

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any]) {
    if let editedImage = info[UIImagePickerController.InfoKey.editedImage] as? UIImage {
        self.imgProfile.image = editedImage
    } else if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
        self.imgProfile.image = image
    }
    self.dismiss(animated: true, completion: nil)
}

要启用编辑，

let picker = UIImagePickerController()
picker.allowsEditing = true
