推荐答案

你可以这样做，点击链接并使用你的操作表

You can do like this , catch a tap on link and use your actionsheet then

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType 
{
    NSURL *requestURL = [ request URL];

    if (navigationType == UIWebViewNavigationTypeLinkClicked)
    {
        // Call your custom actionsheet and use the requestURL to do what you want :)
        return NO;
    }

    return YES;
}


- (void)viewDidLoad
{
    [super viewDidLoad];


     webview.delegate=self;
     [webview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://google.com"]]];



}
