I'm using UIWebView to play YouTube videos in an iPad.
How can I detect when a YouTube video is finished playing?
I see the play icon in the status bar and I tried to use MPMusicPlayerController notifications to detect playbackStateDidChange, but it didn't work.
Any ideas how to detect this event? Again, I'm talking about iPad not iPhone.
Thanks in advance.
Update:
If you use zero solution to detect the end of playing and also want the Youtube video to start automatically set the UIWebView to :
self.webView.mediaPlaybackRequiresUserAction = NO ;
I just want to clarify about the YouTube frame API:

No, there's no way to directly get web page event from UIWebView. But we can accomplish this by using Javascript.
These links may help:
Calling Objective-C from JavaScript in an iPhone UIWebView

YouTube iFrame API
updated with an example:
in UIWebView's delegate, i put:
#pragma - mark WebView Delegate
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if ( [[[request URL] scheme] isEqualToString:@"callback"] ) {
NSLog(@"get callback");
return NO;
}
return YES;
}
the web page is load when viewDidLoad:
[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"youtube" ofType:@"html" ]]]];
and in youtube.html i put:
<html>
<body>
<!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
<div id="player"></div>
<script>
// 2. This code loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "http://www.youtube.com/player_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 3. This function creates an <iframe> (and YouTube player)
// after the API code downloads.
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: 'u1zgFlCw8Aw',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
event.target.playVideo();
}
// 5. The API calls this function when the player's state changes.
// The function indicates that when playing a video (state=1),
// the player should play for six seconds and then stop.
var done = false;
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING && !done) {
setTimeout(stopVideo, 6000);
done = true;
}
if (event.data == YT.PlayerState.ENDED) {
window.location = "callback:anything"; //here's the key
};
}
function stopVideo() {
player.stopVideo();
}
</script>
</body>
</html>
you can see i add
if (event.data == YT.PlayerState.ENDED) {
window.location = "callback:anything";
};
to YouTube's iFrame API demo, and it catches the player end playing event and try to load a request with scheme "callback", then the UIWebView Delegate could catch it.
You can use this method to trigger any event using JavaScript;

please refere to:
https://developer.apple.com/library/ios/#documentation/AVFoundation/Reference/AVPlayerItem_Class/Reference/Reference.html
there is an notification available iOS 4.0 , which you can use to detect youtube video finish playing
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(youTubePlayed:) name:AVPlayerItemDidPlayToEndTimeNotification object:nil];
