我正在尝试与UIWebView中的已加载页面进行交互而不触摸屏幕。我尝试过mediaplaybackrequiresuseraction没有成功。我也尝试了here提供的方法，但显然它在ios 6中不起作用。我正在尝试加载this url并让播放器开始播放。有谁知道如何使这项工作ios 6？非常感谢任何帮助。
我的代码
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1];
NSString * storyLink = [[stories objectAtIndex: storyIndex] objectForKey: @"link"];
//storyLink is various form of http://link.brightcove.com/services/player/bcpid1683318714001?bckey=AQ~~,AAAAC59qSJk~,vyxcsD3OtBPHZ2UIrFX2-wdCLTYNyMNn&bclid=1644543007001&bctid=2238216269001 with different bctid=value
NSURL *kitcoURL = [NSURL URLWithString:storyLink];
NSURLRequest *requestURL = [NSURLRequest requestWithURL:kitcoURL];
[videoScreen setUserInteractionEnabled:YES];
[videoScreen setMediaPlaybackRequiresUserAction:NO];
[videoScreen loadRequest:requestURL];
}
//方法无法在ios6中工作
- (UIButton *)findButtonInView:(UIView *)view {
UIButton *button = nil;
if ([view isMemberOfClass:[UIButton class]]) {
return (UIButton *)view;
}
if (view.subviews && [view.subviews count] > 0) {
for (UIView *subview in view.subviews) {
button = [self findButtonInView:subview];
if (button) return button;
}
}
return button;
}
- (void)webViewDidFinishLoad:(UIWebView *)_webView {
UIButton *b = [self findButtonInView:_webView];
[b sendActionsForControlEvents:UIControlEventTouchUpInside];
}
EDIT // videoScreen是我的UIWebView
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *urlString = @"http://link.brightcove.com/services/player/bcpid1683318714001?bckey=AQ~~,AAAAC59qSJk~,vyxcsD3OtBPHZ2UIrFX2-wdCLTYNyMNn&bclid=1644543007001&bctid=2238216269001";
NSError *error;
NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"bckey=([^&]*)" options:0 error:&error];
NSTextCheckingResult *match = [regex firstMatchInString:urlString options:0 range:NSMakeRange(0, urlString.length)];
NSString *bckey = [urlString substringWithRange:[match rangeAtIndex:1]];
regex = [NSRegularExpression regularExpressionWithPattern:@"bctid=([0-9]*)" options:0 error:&error];
match = [regex firstMatchInString:urlString options:0 range:NSMakeRange(0, urlString.length)];
NSString *bctid = [urlString substringWithRange:[match rangeAtIndex:1]];
NSString *newUrlString = [NSString stringWithFormat:@"http://c.brightcove.com/services/viewer/htmlFederated?&playerKey=%@&videoID=%@", bckey, bctid];
[videoScreen loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:newUrlString]]];
}
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
if (!webView.isLoading)
{
[self checkForVideoReady];
}
}
// Checking player object for ready. If it ready - starting video. Otherwise waiting 1 second
- (void)checkForVideoReady
{
if (![[videoScreen stringByEvaluatingJavaScriptFromString:@"player.ready"] isEqualToString:@"true"])
{
[self performSelector:@selector(checkForVideoReady) withObject:nil afterDelay:1];
}
else
{
[videoScreen stringByEvaluatingJavaScriptFromString:@"player.videoPlayer.playButton.element.click();"];
}
}

如果你只想播放一首歌，那么＆amp;当webview加载时然后你需要在
中调用播放功能 `- (void)webViewDidFinishLoad:(UIWebView *)webView {
// Do whatever you want here
// play song
}`
但请确保您已将代理人分配给您的网页浏览
<UIWebView_object>.delegate = self;
这将自动播放歌曲＆amp;加载webview时
享受编程!!

基于HTML 5 Youtube视频查看按钮的方法。
我找到了解决问题的方法，它并不优雅，但却在工作。
您的链接
使用flash对象下载页面。据我所知，没有办法开始使用JS或UIWebView播放它
在研究请求后，我看到UIWebView查询了另一个网址：
第二个更有趣，因为我们可以访问player变量并使用JavaScript启动视频。
所以我们需要转换初始网址。好像我们在网址中只有两个重要参数 - bckey和bctid：
NSString *urlString = @"http://link.brightcove.com/services/player/bcpid1683318714001?bckey=AQ~~,AAAAC59qSJk~,vyxcsD3OtBPHZ2UIrFX2-wdCLTYNyMNn&bclid=1644543007001&bctid=2238216269001";
NSError *error;
NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"bckey=([^&]*)" options:0 error:&error];
NSTextCheckingResult *match = [regex firstMatchInString:urlString options:0 range:NSMakeRange(0, urlString.length)];
NSString *bckey = [urlString substringWithRange:[match rangeAtIndex:1]];
regex = [NSRegularExpression regularExpressionWithPattern:@"bctid=([0-9]*)" options:0 error:&error];
match = [regex firstMatchInString:urlString options:0 range:NSMakeRange(0, urlString.length)];
NSString *bctid = [urlString substringWithRange:[match rangeAtIndex:1]];
NSString *newUrlString = [NSString stringWithFormat:@"http://c.brightcove.com/services/viewer/htmlFederated?&playerKey=%@&videoID=%@", bckey, bctid];
并加载新网址
[_webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:newUrlString]]];
加载网址后，我们可以访问player个对象。此对象可以判断视频何时可以播放并开始播放
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
if (!webView.isLoading)
{
[self checkForVideoReady];
}
}
// Checking player object for ready. If it ready - starting video. Otherwise waiting 1 second
- (void)checkForVideoReady
{
if (![[_webView stringByEvaluatingJavaScriptFromString:@"player.ready"] isEqualToString:@"true"])
{
[self performSelector:@selector(checkForVideoReady) withObject:nil afterDelay:1];
}
else
{
[_webView stringByEvaluatingJavaScriptFromString:@"player.videoPlayer.playButton.element.click();"];
}
}
我知道这不优雅，也许有人会找到一种方法来改善它 随意评论。

您可以在网页视图中加载的网页的javascript中显示“自动播放”。
答案 3 :(得分：1)
- (void)videoThumb:(NSString *)urlString frame:(CGRect)frame {
NSString *embedHTML = @"\
<html><head>\
<style type=\"text/css\">\
body {\
background-color: transparent;
color: white;
}\
</style>\
</head><body style=\"margin:0\">\
<embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" \
width=\"%0.0f\" height=\"%0.0f\"></embed>\
</body></html>";
NSString *html = [NSString stringWithFormat:embedHTML, urlString, frame.size.width,frame.size.height];
[webView loadHTMLString:html baseURL:nil];
[self.view addSubview:webView];
[webView release];
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
//Include above function to your page and call it by passing the urlstring
//frame : this parameter needs the size of the thumb you want to use.
[self videoThumb:url:frame];
}
只需通过您想要播放的网址来调用videoThumb功能即可。
