Question

我正在尝试使用此代码使应用程序如此频繁地拍照

import UIKit

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
    var cameraIsOn = false

    let imagePicker = UIImagePickerController()
    var timeInterval = 15

    override func viewDidLoad() {
        super.viewDidLoad()

        imagePicker.delegate = self
        imagePicker.allowsEditing = false
        imagePicker.sourceType = .camera
    }

    @IBAction func PlayButton(_ sender: UIBarButtonItem) {
        present(imagePicker, animated: true) {
            self.cameraIsOn = true
            self.imagePicker.takePicture()
        }
    }

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
            imageView.image = image
        }

        imagePicker.dismiss(animated: true) {
            self.present(self.imagePicker, animated: true) {
                self.cameraIsOn = true

                if self.cameraIsOn {
                    DispatchQueue.main.asyncAfter(deadline: .now() + .seconds(self.timeInterval * 60), execute: {
                    self.imagePicker.takePicture()
                    })
                }
            }
        }
    }

    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        cameraIsOn = false
    }
}

拍照后。系统会显示“重新拍摄或使用照片屏幕”。

我正在尝试以编程方式按下“使用照片”按钮，以便我可以完成循环，直到有人按下取消。

不确定要查找的按钮（使用照片）操作！但可以通过编程方式调用/按下UIButton。试试这个

yourButton.sendActions（用于：.touchUpInside）

让您的问题更详细会更好。您的情况是什么？您到底想实现什么目标？
