Пользовательская камера на UIView, а не во весь экран

Question

Я делаю приложение, которое на определенной части приложения позволяет сделать снимок с камеры или выбрать из альбома, и это изображение будет показано на ViewController. Это довольно просто, но, что мне нужно, что я не могу это сделать: -I не хочу, чтобы камера открывалась во весь экран, я хочу, чтобы она открывала на ViewController, что пользователь находится в том же месте, где и будет изображение, внутри круга. Мне удалось сделать камеру не открытой во весь экран, но я не могу поместить этот вид в круг и обрезать фотографию в соответствии с кругом.

Вот мой код, он может работать, если вы создать стандартный проект, и я думаю, что поможет понять, что происходит:

Answer 1

С помощью приведенного ниже кода я получаю следующие результаты:

1. Единый вид с темно-синим фоном.
2. 2 зеленых круга (кнопки)
3. Нажатие на левый круг помещает в него «зрение» камеры.
4. Нажатие на кнопку «взять» (в нижней части круга слева) отключает метод «takePhotoAction».

Answer 2

Решено вопрос о «меньшего изображения» на PhotoView после съемки, обрезав его как квадрат и только после того, как установите образ PhotoView.

Решение вопроса «изображение вверх» немного изменилось после установки изображения на PhotoView путем «установки» кадра picker.view на x: 0, y: -50, PhotoView.width, PhotoView.height.

Вот fullcode:
