设置数据

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType; {

        NSString *password = [self.webView stringByEvaluatingJavaScriptFromString: @"document.myForm.password.value"];

        [SFHFKeychainUtils storeUsername:username andPassword:password forServiceName:@"MyService" updateExisting:YES error:nil];

    }    

}

获取数据

- (void)webViewDidFinishLoad:(UIWebView *)webView{

    if ([requestURL.host isEqualToString:@"www.mydomain.com"]) …
