comment enregistrer le fichier vidéo dans le répertoire du document

Je suis en train de capturer une vidéo en utilisant le code suivant:

UIImagePickerController *ipc = [[UIImagePickerController alloc] init];
ipc.sourceType =  UIImagePickerControllerSourceTypeCamera;
ipc.delegate = self;
//need to handle delegates methods 
//
ipc.allowsEditing = YES;
ipc.videoQuality = UIImagePickerControllerQualityTypeMedium;
ipc.videoMaximumDuration = 30.0f; // 30 seconds
//temporary duation of 30 seconds for testing

ipc.mediaTypes = [NSArray arrayWithObject:@"public.movie"];
// ipc.mediaTypes = [NSArray arrayWithObjects:@"public.movie", @"public.image", nil];
[self presentModalViewController:ipc animated:YES]; 
//this controller allows to record the videos

et je peux sauvegarder une vidéo enregistrée dans un album en utilisant le code suivant

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{ 
    // recover video URL
    NSURL *url = [info objectForKey:UIImagePickerControllerMediaURL];

    // check if video is compatible with album
    BOOL compatible = UIVideoAtPathIsCompatibleWithSavedPhotosAlbum([url path]);

    // save
    if (compatible){
        UISaveVideoAtPathToSavedPhotosAlbum([url path], self, @selector(video:didFinishSavingWithError:contextInfo:), NULL);
        NSLog(@"saved!!!! %@",[url path]);
    }
    [self dismissModalViewControllerAnimated:YES];
    [picker release];
}

mais je dois récupérer ce fichier de l'album et le stocker dans le répertoire du document?

L’enregistrement de la vidéo dans le répertoire des documents est le suivant:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

    NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
    NSData *videoData = [NSData dataWithContentsOfURL:videoURL];
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *tempPath = [documentsDirectory stringByAppendingFormat:@"/vid1.mp4"];
    BOOL success = [videoData writeToFile:tempPath atomically:NO];
    [picker dismissModalViewControllerAnimated:YES];
}

Voici le code Swift si quelqu'un en a besoin à l'avenir:

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {

    let videoURL = info[UIImagePickerControllerMediaURL] as! NSURL
    let videoData = NSData(contentsOfURL: videoURL)
    let paths = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)
    let documentsDirectory: AnyObject = paths[0]
    let dataPath = documentsDirectory.stringByAppendingPathComponent("/vid1.mp4")

    videoData?.writeToFile(dataPath, atomically: false)
    self.dismissViewControllerAnimated(true, completion: nil)

}

Peu de R & D, cela a fonctionné pour moi 

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

{

 NSURL *url = [info objectForKey:UIImagePickerControllerMediaURL];
  // Save video to app document directory

NSString *filePath = [url path];
NSString *pathExtension = [filePath pathExtension] ;
if ([pathExtension length] > 0)
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) ;
    NSString *documentsDirectory = [paths objectAtIndex:0];

    NSString *localFilePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@", [filePath lastPathComponent]]];

   // Method last path component is used here, so that each video saved will get different name.

    NSError *error = nil ;
    BOOL res = [[NSFileManager defaultManager] moveItemAtPath:filePath toPath:localFilePath error:&error] ;

    if (!res)
    {
        NSLog(@"%@", [error localizedDescription]) ;
    }
    else
    {
       NSLog(@"File saved at : %@",localFilePath);
    }
}

}

// Aussi, lorsque vous devez vérifier que la même vidéo existe déjà dans le répertoire du document d'application et que vous ne voulez pas en créer plusieurs copies, apportez les modifications ci-dessous. 

NSURL *url = [info objectForKey:UIImagePickerControllerMediaURL];
NSURL *videoAsset = [info objectForKey:UIImagePickerControllerReferenceURL];

__weak typeof(self) weakSelf = self;

ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library assetForURL:videoAsset resultBlock:^(ALAsset *asset)
{
    weakSelf.selectedFileName = [[asset defaultRepresentation] filename];
    NSLog(@"Video Filename %@",weakSelf.selectedFileName);

    // Save video to doc directory
    NSString *filePath = [url path];
    NSString *pathExtension = [filePath pathExtension] ;
    if ([pathExtension length] > 0)
    {
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) ;
        NSString *documentsDirectory = [paths objectAtIndex:0];

        NSString *localFilePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@", weakSelf.selectedFileName]];

        //check if same video is having its copy in app directory.
        //so that multiple entries of same file should not happen.

        BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:localFilePath];

        if (!fileExists)
        {
            NSError *error = nil ;

            BOOL res = [[NSFileManager defaultManager] moveItemAtPath:filePath toPath:localFilePath error:&error] ;

            if (!res)
            {
                NSLog(@"%@", [error localizedDescription]) ;
            }
            else
            {
                NSLog(@"File saved at : %@",localFilePath);
                weakSelf.filePathURL = [NSURL URLWithString:localFilePath];
            }
        }
        else
        {
            NSLog(@"File exist at : %@",localFilePath);
            weakSelf.filePathURL = [NSURL URLWithString:localFilePath];
        }

    }
}

}

// Où faibleSelf.selectedFileName et faibleSelf.filePathURL sont respectivement les propriétés de type NSString et NSURL de ma classe.

Nous pouvons utiliser la méthode moveItemAtPath:toPath:error: de NSFileManager pour déplacer le fichier vidéo dans le répertoire de documents de notre application. C'est plus efficace.

Nous devrions également obtenir l'extension du fichier vidéo et l'utiliser comme extension de notre nom de fichier vidéo local.

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    [self dismissViewControllerAnimated:YES completion:nil] ;

    if ([info[UIImagePickerControllerMediaType] isEqualToString:(NSString *)kUTTypeMovie]) {
        // video
        NSURL *url = [info[UIImagePickerControllerMediaType] ;
        NSString *filePath = [url path] ;
        NSString *pathExtension = [filePath pathExtension] ;
        if ([pathExtension length] > 0) {
            NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) ;
            NSString *documentsDirectory = [paths objectAtIndex:0] ;
            NSString *localFilePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"temp.%@", pathExtension]] ;
            NSError *error = nil ;
            BOOL res = [[NSFileManager defaultManager] moveItemAtPath:filePath toPath:localFilePath error:&error] ;
            if (!res) {
                NSLog(@"%@", [error localizedDescription]) ;
            }
        }
    }
}

Ça marche pour moi.
