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"]]];
}
