Ios 使用MPMOVIEWPLAYERCONTROLER播放受Windows身份验证保护的mp4视频（url）

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

- (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;  
}  

我已经实现了一些代码，我相信我快成功了

- (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;  
}  

因此，我尝试使用NSURLConnection“解锁”MP4URL。它可以工作，但是当我尝试使用initWithContentURL访问同一个url时，它不起作用。（它无法“看到”我以前输入的信息

- (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;  
}  

因此，问题是：如何永久锁定文件夹/url，或者如何为MPMoviePlayerController提供NSURL连接而不是NSURL

- (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;  
}  

1-因此，以下是我采取的步骤：

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

- (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;  
}  

2-->我正在尝试访问受保护的URL（此操作正常）

- (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;  
}  

3-这是正确的称呼

- (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-这是正确的称呼

- (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;  
}  

- (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，这很好，因为我知道url是解锁的。那么…如何使用MPMoviePlayer播放它

- (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;  
}  

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

4-保持黑色…：(

- (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;  
}

我也尝试过这个：（运气不好，很抱歉格式化）-（void）连接：（NSURLConnection*）连接didReceiverResponse：（nsurResponse*）响应；{NSURL*movieURL=[NSURL URLWithString:@；moviePlayer=[MPMoviePlayerController alloc]初始化WithContentUrl:connection.currentRequest.URL]；moviePlayer=[[MPMoviePlayerController alloc]init]；moviePlayer.controlStyle=MPMovieControlStyleFullscreen；moviePlayer.shouldAutoplay=YES；…[self.view addSubview:[moviePlayer视图]]；}最后一条评论：即使我试图直接从safari访问视频，它也不会出现！从一个没有身份验证的链接，它会出现，从一个请求（并提供）身份验证的链接，我得到一个带有“停止”的视频。
