[IOS/研究]UIWebView拦截[近期完成，待续]

拦截位置在于以下UIWebViewDelegate下的函数方法
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType;

• 点击拦截
  NSURL *requestURL = request.URL;
if (([[requestURL scheme] isEqualToString: @"http"] ||
[[requestURL scheme] isEqualToString: @"https"] ||
[[requestURL scheme] isEqualToString: @"mailto"]) &&
(navigationType == UIWebViewNavigationTypeLinkClicked))
{
NSLog(@"点击拦截");
return false;
}
