有人能帮我下载这个视频吗？

要下载一个文件，我使用了以下代码。希望它也能对你有用

    Try this here your video is playing..

 - (void)viewDidLoad
{
  [super viewDidLoad];
  UIWebView*  webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 380)]; 
    webView.delegate=self;
   [webView setOpaque:NO];
    webView.backgroundColor=[UIColor clearColor];
    CGRect screen = [[UIScreen mainScreen] bounds];
    CGFloat width = CGRectGetWidth(screen);
    CGFloat height = CGRectGetHeight(screen);
   UIActivityIndicatorView * activityIndicator = [[UIActivityIndicatorView alloc]        initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
    activityIndicator.frame=CGRectMake((width/2) - 10,(height/2) - 54, 20, 20);
    activityIndicator.center=self.view.center;
    [activityIndicator hidesWhenStopped];

   [self  playVideo];
}
  -(void) playVideo
    {
     NSURL *url = [NSURL URLWithString:@"http://player.vimeo.com/video/32983838"];
            NSURLRequest *request = [NSURLRequest requestWithURL:url];
            [self.webView loadRequest:request];
            [activityIndicator startAnimating];
            [webView addSubview:activityIndicator];
    }

    /*   WebViewDidStartLoad   */
    - (void)webViewDidStartLoad:(UIWebView *)webView
    {
       [activityIndicator startAnimating];
        [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES]; 
    }

    /*   WebViewDidFinishLoad   */
    - (void)webViewDidFinishLoad:(UIWebView *)webView
    {
         [activityIndicator stopAnimating];
        [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO]; 
    }
    /*   WebViewdidFailLoadWithError   */
    - (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
    {
        [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO]; 
    }

- (IBAction)getFileFromFtpServer:(UIView *)sender
{

  NSString *stringURL = @"http://player.vimeo.com/video/32983838";
NSURL  *url = [NSURL URLWithString:stringURL];
NSData *urlData = [NSData dataWithContentsOfURL:url];
if ( urlData )
{
  NSArray       *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
  NSString  *documentsDirectory = [paths objectAtIndex:0];  

  NSString  *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"filename.mpeg4"];
  [urlData writeToFile:filePath atomically:YES];
}


}

如果我理解正确并回应上述内容，谷歌因侵犯版权而关闭了几个“转换器网站”：还有其他网站可以下载视频内容（同样，假设你遵守版权准则）：这列出了五个你可以免费查找和下载在线视频的网站。要确保下载视频是合法的，请查找有关该视频的许可信息。通常，具有“Creative Commons”许可证的视频下载是合法的，但可能对如何使用视频有限制

Youtube最近限制了任何外部来源的视频下载。您将不被允许从任何软件或应用程序下载任何YouTube视频。你只能在UIWebView中查看它们。你检查过链接吗？这不是youtube链接是的，我检查过。。。但它只是播放视频，对吗？是的，我想下载这样的视频，但我不知道如何下载？我告诉过你，这是不允许的。。我在安卓手机上有一个下载youtube视频的应用程序，但从10天开始。它停止工作了。。我搜索了一下，发现现在已经不允许了。这只是为了播放一段视频，我需要下载NSSTRING VideoPath；NSURL*URLDIVEO=[NSURL URLWithString:@“URLDIVEODATA=[NSData DATA WITHCONTENTSOFURL:URLDIVEO]；if（URLDIVEODATA{NSArray*pathVideo=NSSearchPathForDirectoriesIndomain（NSDocumentDirectory，NSUserDomainMask，YES）；NSString*documentsDirectory=[pathVideo ObjectIndex:0]；VideoPath=[NSSTRINGWITHFORMAT:@%/%@，“DocumentsDirectority，@”youtubeVideo“]；[urlVideoData writeToFile:filePath原子：是]；}[webView加载请求：[NSURLRequest requestWithURL:[NSURL URLrequestWithString:VideoPath]]；尝试此操作您的视频将被下载filePath替换为VideoPath，如[urlVideoData writeToFile:VideoPath原子：是]；请给我正确的答案我没有听到您想要说的话
