Detecting UIWebView finish to play youtube video on iPad

Question

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 ba

No, there's no way to directly get web page event from UIWebView. But we can accomplish this by using Javascript.

• First you use embed Javascript in your custom HTML, to detect video ending play event.
• Then you try to load a scheme-customized request using JavaScript, and UIWebView could catch the request.

These links may help:

1. Calling Objective-C from JavaScript in an iPhone UIWebView

2. Javascript callback in Objective-C

3. 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:

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;
