我正在尝试在不触摸屏幕的情况下与 UIWebView 中加载的页面进行交互。我试过 mediaplaybackrequiresuseraction 但没有成功。我也试过提供的方法here , 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。有谁知道如何使这个工作 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];
}
//方法在ios6中无效
- (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];
}
编辑 //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();"];
}
}
最佳答案
如果你只想播放一首歌,当 webview 加载时。然后你需要在
`- (void)webViewDidFinishLoad:(UIWebView *)webView {
// Do whatever you want here
// play song
}`
但请确保您已像这样将委托(delegate)分配给您的 WebView
<UIWebView_object>.delegate = self;
这将在 webview 加载时自动播放歌曲
享受编程吧!
