[iOS/Swift] 카메라로 동영상 촬영하기

먼저 영상 촬영과 저장을 위해 권한 설정을 해야한다.

import UIKit

class ViewController: UIViewController {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }
    
    @IBAction func videoButton(_ sender: UIButton) {
        let camera = UIImagePickerController()
        camera.delegate = self
        camera.sourceType = .camera
        camera.mediaTypes = UIImagePickerController.availableMediaTypes(for: .camera) ?? []
        self.present(camera, animated: true, completion: nil)
    }
}

extension ViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        
        //동영상 저장
        if let url = info[.mediaURL] as? URL, UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(url.path) {
                    UISaveVideoAtPathToSavedPhotosAlbum(url.path, self, #selector(savedVideo), nil)
                }
        picker.dismiss(animated: true, completion: nil)
    }
    
    @objc func savedVideo(_ videoPath: String, didFinishSavingWithError error: Error?, contextInfo: UnsafeMutableRawPointer?) {
                if let error = error {
                    print(error)
                    return
                }
                print("success")
            }
    
}
