iPhone 视频录制：“cameraCaptureMode 1 不可用，因为 mediaTypes 确实包含 public.movie”

解决 iPhone 视频录制中的 cameraCaptureMode 1 不可用问题

swift
import UIKit
import AVFoundation
class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 检查设备是否支持摄像头
        guard UIImagePickerController.isSourceTypeAvailable(.camera) else {
            print("设备不支持摄像头")
            return
        }
        
        // 创建 UIImagePickerController 实例
        let imagePickerController = UIImagePickerController()
        
        // 配置 mediaTypes 属性，仅包含 public.movie
        imagePickerController.mediaTypes = [kUTTypeMovie as String]
        
        // 配置 cameraCaptureMode 为 1
        imagePickerController.cameraCaptureMode = .video
        
        // 设置代理
        imagePickerController.delegate = self
        
        // 弹出摄像头界面
        present(imagePickerController, animated: true, completion: nil)
    }
}
extension ViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {
    // 实现相应的代理方法
    // ...
