在Swift 4.2中將照片保存到圖像

Question

我在顯示剛拍攝或選擇的照片時出現問題。

下面是左側的imagview和右側的licencePhoto按鈕的圖片。

當我單擊“拍照”時，它允許我拍照或從圖庫中選擇照片，如代碼所示：

@IBAction func seclectOrTakePhoto(_ sender: Any) {

    pickerController.delegate = self
    pickerController.allowsEditing = true

    let alertController = UIAlertController(title: "Add a Picture", message: "Choose From", preferredStyle: .actionSheet)

    let cameraAction = UIAlertAction(title: "Camera", style: .default) { (action) in
        self.pickerController.sourceType = .camera
        self.present(self.pickerController, animated: true, completion: nil)

    }

    let photosLibraryAction = UIAlertAction(title: "Photos Library", style: .default) { (action) in
        self.pickerController.sourceType = .photoLibrary
        self.present(self.pickerController, animated: true, completion: nil)

    }

    let savedPhotosAction = UIAlertAction(title: "Saved Photos Album", style: .default) { (action) in
        self.pickerController.sourceType = .savedPhotosAlbum
        self.present(self.pickerController, animated: true, completion: nil)

    }

    let cancelAction = UIAlertAction(title: "Cancel", style: .destructive, handler: nil)

    alertController.addAction(cameraAction)
    alertController.addAction(photosLibraryAction)
    alertController.addAction(savedPhotosAction)
    alertController.addAction(cancelAction)


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

}

但是，它不會將照片顯示到licensePhoto圖像上，並且在Firebase中，它正在上傳我在圖像視圖中顯示的照片，如下所示，而不是我剛剛用手機拍攝的照片。

我該如何實現？

編輯

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {

    self.licensePhoto.image = image
    self.dismiss(animated: true, completion: nil)


    // any time the photo changes, check the button status
    updateSignupButtonStatus()


}

在搜索並瀏覽了教程之后，我終於有了一些工作：

@objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage
    licensePhoto.contentMode = .scaleAspectFit
    licensePhoto.image = chosenImage
    pickerController.dismiss(animated: true, completion: nil)
}
