如何在iPhone应用程序中从服务器播放videourl

实际上，我使用XMLParser从服务器获取一个URL。 我想在我的应用程序中播放这个videourl。
现在我用`MPMoviePlayerController，但它不工作。 请帮忙！

XMLParser.m

 -(id) loadXMLByURL:(NSString *)urlString { videoNames =[[NSMutableArray alloc]init]; videos = [[NSMutableArray alloc] init]; NSURL *url = [NSURL URLWithString:urlString]; NSData *data = [[NSData alloc] initWithContentsOfURL:url]; parser = [[NSXMLParser alloc] initWithData:data]; parser.delegate = self; [parser parse]; return self; } - (void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes: (NSDictionary *)attributeDict { if ([elementname isEqualToString:@"items"]) { } if ([elementname isEqualToString:@"video"]) { NSLog(@"video"); currentVideo = [Video alloc]; } } - (void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementname isEqualToString:@"video"]) { currentNodeContent2= [[currentNodeContent2 stringByReplacingOccurrencesOfString:@"+" withString:@" "] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; [videos addObject:currentVideo]; currentVideo.content2 = currentNodeContent2; } if ([elementname isEqualToString:@"name"]) { currentNodeContent2= [[currentNodeContent2 stringByReplacingOccurrencesOfString:@"+" withString:@" "] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; [videoNames addObject:currentVideo]; currentVideo.content2 = currentNodeContent2; NSLog(@"%@",currentNodeContent2); } } // in my class.m -(void)playButtonPressed1:(UIButton*)sender { UIButton *btn1 = (UIButton *)sender; Video *currentVideo= [[xmlParservideo videos] objectAtIndex:btn1.tag]; NSString *urlString=currentVideo.content; NSURL *playURL=[[NSURL alloc]initWithString:urlString]; self.player =[[MPMoviePlayerController alloc]initWithContentURL :playURL]; player.view.frame = CGRectMake(0,80,340,360); [self.view addSubview:player.view]; self.player.movieSourceType = MPMovieSourceTypeUnknown; [self.player prepareToPlay]; [self.player play]; }

它没有工作之前，videostring不是一个有效的url。 它指向一个不是video的swf flash文件。 而B只是input到Safari的url显示它不是一个有效的地址。

如果你要处理加载错误，我相信它会说它不是一个有效的URL。
