Ios 无法在web视图中播放单个视频

在我的应用程序中，我需要在

UIWebView

中播放单个视频，我可以在

UIWebView

中播放播放列表

获取视频的链接是：

这是我的密码：

- (void)viewDidLoad
{
    [super viewDidLoad];

    NSString *videoURL=[self getYTUrlStr:stringURL];
    NSURL *url=[NSURL URLWithString:videoURL];
    [self.web loadRequest:[NSURLRequest requestWithURL:url]];


    NSString *videoURL=[self getYTUrlStr:stringURL];
    - (NSString*)getYTUrlStr:(NSString*)url
    {
    if (url == nil)
        return nil;

    NSString *retVal = [url stringByReplacingOccurrencesOfString:@"watch?v=" withString:@"v/"];

    NSRange pos=[retVal rangeOfString:@"version"];
    if(pos.location == NSNotFound)
    {
        retVal = [retVal stringByAppendingString:@"?version=3&hl=en_EN"];
    }
    return retVal;
    }

---

需要修改链接如下

videoURL = [videoURL stringByReplacingOccurrencesOfString:@"http://www.youtube.com/v/" withString:@"http://www.youtube.com/embed/"];
videoURL=[videoURL stringByReplacingOccurrencesOfString:@"?version=3&hl=en_EN" withString:@"?feature=player_detailpag"];
videoURL = [videoURL stringByReplacingOccurrencesOfString:@"?version=3&f=user_uploads&app=youtube_gdata" withString:@"?feature=player_detailpage"];

然后将提供给实例方法的UIWebView实例方法loadRequest作为NSURLRequest
