using a webview to play videos from youtube in iph

I am trying to watch videos in my iphone app using the following code:

-(void) viewDidLoad{
[super viewDidLoad];

UIWebView *webView = [[UIWebView alloc]initWithFrame:self.view.frame];

    NSString *youTubeVideoHTML = @"<html><head>\
    <body style=\"margin:0\">\
    <embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" \
    width=\"%0.0f\" height=\"%0.0f\"></embed>\
    </body></html>";

    // Populate HTML with the URL and requested frame size
    NSString *html = [NSString stringWithFormat:youTubeVideoHTML,@"http://www.youtube.com/watch?v=ZiIcqZoQQwg" , 100, 100];

    // Load the html into the webview
    [webView loadHTMLString:html baseURL:nil];
    [self.view addSubview:webView];
}

Can anyone tell me what I am doing wrong? I've seen this in a couple examples but still I can't work it out!

It looks like your HTML string isn't properly formed.

Try this:

- (void)viewDidLoad {

    [super viewDidLoad];

    float width = 200.0f;
    float height = 200.0f;

    NSString *youTubeURL = @"http://www.youtube.com/watch?v=ZiIcqZoQQwg";

    UIWebView *webView = [UIWebView new];
    webView.frame = CGRectMake(60, 60, width, height);

    NSMutableString *html = [NSMutableString string];
    [html appendString:@"<html><head>"];
    [html appendString:@"<style type=\"text/css\">"];
    [html appendString:@"body {"];
    [html appendString:@"background-color: transparent;"];
    [html appendString:@"color: white;"];
    [html appendString:@"}"];
    [html appendString:@"</style>"];
    [html appendString:@"</head><body style=\"margin:0\">"];
    [html appendFormat:@"<embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\"", youTubeURL];
    [html appendFormat:@"width=\"%0.0f\" height=\"%0.0f\"></embed>", width, height];
    [html appendString:@"</body></html>"];

    [webView loadHTMLString:html baseURL:nil];

    [self.view addSubview:webView];

}

It's worth noting that this code will only work on a device, it won't work in the simulator.

UPDATE...

Due to changes made by YouTube, the method above is now incorrect. Use the method below instead.

- (void)viewDidLoad {

    [super viewDidLoad];

    float width = 200.0f;
    float height = 200.0f;

    NSString *youTubeToken = @"K95Q0VFyhA8";

    UIWebView *wv = [UIWebView new];
    webView.frame = CGRectMake(60, 60, width, height);

    NSMutableString *html = [NSMutableString string];
    [html appendString:@"<html>"];
    [html appendString:@"<head>"];
    [html appendString:@"<style type=\"text/css\">"];
    [html appendString:@"body {"];
    [html appendString:@"background-color: transparent;"];
    [html appendString:@"color: white;"];
    [html appendString:@"margin: 0;"];
    [html appendString:@"}"];
    [html appendString:@"</style>"];
    [html appendString:@"</head>"];
    [html appendString:@"<body>"];
    [html appendFormat:@"<iframe id=\"ytplayer\" type=\"text/html\" width=\"%0.0f\" height=\"%0.0f\" src=\"http://www.youtube.com/embed/%@\" frameborder=\"0\"/>", width, height, videoToken];
    [html appendString:@"</body>"];
    [html appendString:@"</html>"];

    [wv loadHTMLString:html baseURL:nil];

    [self.view addSubview:wv];

}

I have the same problem. I solved this by following method.

Replace the youtube Use http://www.youtube.com/v/XXXXXXX

instead of http://www.youtube.com/watch?v=XXXXXXX

try this simple one :

//get the youtube video token from youtube url //https://www.youtube.com/watch?v=youTubeToken

 NSString *youTubeToken = @"K95Q0VFyhA8";

//create webview..
    UIWebView *webView = [UIWebView new];
    webView.frame = CGRectMake(10, 10, 300, 300);

//load webview with the load request..
    [webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"https://www.youtube.com/embed/%@",youTubeToken]]]];
    [self.view addSubview:webView];
