在调用webview完成加载委托时，你必须编写一些java脚本代码。

- (void)webViewDidFinishLoad:(UIWebView *)webView{
    NSURLRequest* request = [webView request];
    NSString *page = [request.URL lastPathComponent];
    if ([page isEqualToString:@"index.html"]){
        NSString *js = @"startVideo();";
        [myWebMain stringByEvaluatingJavaScriptFromString:js];
    }
}
And here's my javascript function:

<script>
function startVideo(){
var pElement3 = document.getElementById('myVideo');
pElement3.play();
}
</script>
And here's the html in case you're new to html video

<video id="myVideo" poster="index_poster.png" width="1024" height="768" xcontrols     autoplay="autoplay">
<source src="flow.m4v" type="video/mp4"/>
browser not supports the video
</video>
