  是的，可以询问用户确认 .

  用户UIWebView委托方法：

  - (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType {
  self.URL = [request URL];
  if (navigationType == UIWebViewNavigationTypeLinkClicked)
  {
      AVURLAsset* asset;
  
      self.songURL = [NSString stringWithFormat:@"%@",self.URL];
  
      //Check for supported song formatted 
      if([self.songURL hasSuffix:@".mp3"] ||
         [self.songURL hasSuffix:@".wav"] ||
         [self.songURL hasSuffix:@".aiff"] ||
         [self.songURL hasSuffix:@".aac"] ||
         [self.songURL hasSuffix:@".m4a"] ||
         [self.songURL hasSuffix:@".m4p"] ||
         [self.songURL hasSuffix:@".caf"])
      {
  
          asset = [[AVURLAsset alloc]initWithURL:self.URL options:nil];
  
          if(asset != nil)
          {
              UIActionSheet *actSheet = [[UIActionSheet alloc]
                                         initWithTitle:@"Songs"
                                         delegate:self
                                         cancelButtonTitle:@"Cancel"
                                         destructiveButtonTitle:@"Download"
                                         otherButtonTitles:@"Listen Online", nil];
              [actSheet showInView:self.view];
          }
          [asset release];
          return NO;
  
      }
  }
  return YES;
  }
  

  在UIActionSheetDelegate方法上：

  -(void) actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
  {
    if(buttonIndex == 1)
    {
       [self.webView loadRequest:[NSURLRequest requestWithURL:self.URL]];
   }
  }
