Answer 1

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(playerItemBecameCurrent:)
                                             name:@"AVPlayerItemBecameCurrentNotification"
                                           object:nil];


- (void)playerItemBecameCurrent:(NSNotification*)notification 
{
        AVPlayerItem *playerItem = [notification object];
        if(playerItem == nil) return;

        // Break down the AVPlayerItem to get to the path
        AVURLAsset *asset = (AVURLAsset*)[playerItem asset];
        NSURL *url = [asset URL]; // this is URL you need
}

Answer 2

如果您只想获取 URL，请尝试以下代码：

NSString *currentURL = [webView stringByEvaluatingJavaScriptFromString:@"window.location"];

但是，如果您想获取所有事件，只需使用 webview 委托方法：

    - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
        NSString *URLString = [[request URL] absoluteString];
        //now you have the url;
       return YES;
   }
