Question

我想使用网络视图下载视频，但我没有得到如何下载它？我的视频链接是here

我正在使用的播放视频的示例代码是

-(void)embedYouTubeInWebView:(NSString*)url theWebView:(UIWebView *)aWebView {
    NSString* html = [NSString stringWithFormat:@"%@", url];
    [aWebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:html]]];
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    
   [self embedYouTubeInWebView:@"http://player.vimeo.com/video/32983838" theWebView:myWebView];
    // Do any additional setup after loading the view, typically from a nib.
}

有人可以帮我下载这个视频吗？

Answer 1

要下载文件，我使用以下代码。希望它也适合你。

- (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];
}


}

    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]; 
    }

如果我理解正确并且在上面的回应中，谷歌因版权侵权而关闭了几个“转换网站”：http://www.real.com/resources/youtube-to-mp3-converter还有其他网站可以下载视频内容（再次假设您已经过了根据版权指南）：这列出了五个网站，您可以在这些网站免费查找和下载在线视频。要确保视频合法下载，请查找有关视频的许可信息。通常情况下，具有“知识共享”许可的视频下载是合法的，但可能会限制您使用视频的方式。 http://www.real.com/resources/download-one-video
