사진 라이브러리 Swift에 비디오 저장 (Save video in Photo Library Swift)
내 사진 라이브러리에 비디오를 저장하는 방법을 알아내려고 합니다. 시작하려면 UIImagePickerController를 사용하여 비디오를 선택하고 선택한 후 UISaveVideoAtPathToSavedPhotosAlbum을 사용하여 라이브러리에 다시 저장하려고 했습니다. 별 의미는 없지만 동영상 저장이 어떻게 작동하는지 이해하려고 노력합니다.
다음 코드는 동영상을 저장하지 않으므로 작동하지 않습니다.
@IBAction func ChooseVideo(_ sender: Any) {
let imagePickerController = UIImagePickerController()
imagePickerController.delegate = self
imagePickerController.mediaTypes = ["public.movie"]
self.present(imagePickerController, animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
let videoURL = info[UIImagePickerController.InfoKey.mediaURL] as? URL
print(UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(videoURL!.path))
dismiss(animated: true, completion: {
UISaveVideoAtPathToSavedPhotosAlbum(videoURL!.path, self, #selector(self.video(_:didFinishSavingWithError:contextInfo:)), nil)
})
}
할 수 있기를 바랍니다. 동영상 저장에 대해 많은 정보를 찾지 못했기 때문에 도와주세요.
안녕하세요, MB
해결책:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any])
{
// *** store the video URL returned by UIImagePickerController *** //
let videoURL = info[UIImagePickerController.InfoKey.mediaURL] as! URL
// *** load video data from URL *** //
let videoData = NSData(contentsOf: videoURL)
// *** Get documents directory path *** //
let paths = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)[0]
// *** Append video file name *** //
print(paths)
let dataPath = paths.appending("/videoFileName.mp4")
// *** Write video file data to path *** //
videoData?.write(toFile: dataPath, atomically: false)
PHPhotoLibrary.shared().performChanges({
PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: URL(fileURLWithPath: dataPath))
}) { saved, error in
if saved {
let fetchOptions = PHFetchOptions()
fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
let fetchResult = PHAsset.fetchAssets(with: .video, options: fetchOptions).firstObject
// fetchResult is your latest video PHAsset
// To fetch latest image replace .video with .image
}
}
}

방법 1:
Use following func to save video to documents directory
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject])
{
// store the video URL returned by UIImagePickerController //
let videoURL = info[UIImagePickerControllerMediaURL] as! NSURL// *** load video data from URL *** // let videoData = NSData(contentsOfURL: videoURL) // *** Get documents directory path *** // let paths = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)[0] // *** Append video file name *** // let dataPath = documentsDirectory.stringByAppendingPathComponent("/videoFileName.mp4") // *** Write video file data to path *** // videoData?.writeToFile(dataPath, atomically: false)}
</code></pre></li>now save this video in photo gellary
PHPhotoLibrary.shared().performChanges({
PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: Your document directory file)
}) { saved, error in
if saved {
let fetchOptions = PHFetchOptions()
fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]let fetchResult = PHAsset.fetchAssets(with: .video, options: fetchOptions).firstObject // fetchResult is your latest video PHAsset // To fetch latest image replace .video with .image }}
</code></pre></li>
</ul>after it if you don't need then delete the image from document directory , I hope it will work for you ...:)
