我有一个受 Windows 身份验证保护的 .mp4 视频（url）。我想使用 MPMoviePlayerController 播放。

我已经实现了一些代码，我确定我已经接近了！

所以，我正在尝试使用 NSURLConnection 来“解锁”mp4 url​​。它可以工作，但是当我尝试使用 initWithContentURL 访问相同的 url 时，它不起作用。（它不能“看到”我之前输入的信息。

所以，问题是；如何永久锁定文件夹/url，或者如何为 MPMoviePlayerController 提供 NSURLConnection 而不是 NSURL。

1-所以，这是我采取的步骤：

- (void)viewDidLoad{
    [super viewDidLoad];
    //[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL       URLWithString:@"http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"]]];
    [self tryConnection];
}

2--> 我正在尝试访问受保护的 URL（这是有效的）

- (void) tryConnection{
    NSURLRequest* request = [[NSURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://www.abcd.com/_develop/video/01.mp4"]];
    NSURLConnection* connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
                         //[request release];
                         //[connection release];
}

3-这是正确调用的 

- (BOOL)connection:(NSURLConnection*)conn  canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace*)protectionSpace {  
    if([[protectionSpace authenticationMethod] isEqualToString:NSURLAuthenticationMethodNTLM])  
        return YES;  

    // Explicitly reject ServerTrust. This is occasionally sent by IIS.  
    if([[protectionSpace authenticationMethod] isEqualToString:NSURLAuthenticationMethodServerTrust])  
        return NO;  

    return NO;  
}

4-这是正确调用的 

- (void)connection:(NSURLConnection*)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge*)challenge{
    NSLog(@"didReceiveAuthenticationChallenge");
        if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodNTLM])
            [[challenge sender] useCredential:[NSURLCredential  
                                          credentialWithUser:@"1234"  
                                          password:@"5678"  
                                          persistence:NSURLCredentialPersistenceNone] forAuthenticationChallenge:challenge]; 

}

4-这是正确调用的。从这里开始，太好了，因为我知道该 url 是 Unlock。那么...如何使用 MPMoviePlayer 播放它？

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response;{
    NSLog(@"received response via nsurlconnection");
    [self moviePlayerGO];
}

4-保持黑色... :(

-(void)moviePlayerGO{
    NSURL *movieURL = [NSURL URLWithString:@"http://www.abcd.com/_develop/video/01.mp4"];
    //NSURL *movieURL = [NSURL URLWithString:@"http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"];
    moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
    moviePlayer.controlStyle = MPMovieControlStyleFullscreen;
    moviePlayer.shouldAutoplay = YES;
    [[moviePlayer view] setFrame: CGRectMake(0.0, 0.0, 350.0, 250.0)]; // 2X the native resolution
    [self.view addSubview: [moviePlayer view]];
}
