如何通过操纵快门按钮

Question

了解iPhone有自动设置定时拍照功能，自动拍摄照片。之后按下快门按钮启动。

我想要做类似的事情。所以如何在相机启动后以编程方式处理快门按钮。

- implement: UINavigationControllerDelegate, UIImagePickerControllerDelegate 

class ViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate { 

var imagePicker: UIImagePickerController! 


} 

//-- launch the camera 

    @IBAction func takePhoto(_ sender: UIButton) { 

     imagePicker = UIImagePickerController() 
     imagePicker.delegate = self 
     imagePicker.sourceType = .camera 
     present(imagePicker, animated: true, completion: nil) 
    } 

所以，相机推出后，如何通过编程处理的快门按钮类似点击它来拍照？

因此，相机启动后，如何以编程方式处理快门按钮，如点击它来拍照？

告诉UIImagePickerController到takePicture。
