(BOOL) webView... not firing on all requests

I'm working on an iOS app using UIWebViews, and I'm running in to some interesting behavior.

I'm trying to load content from my website into an iOS app via a UIWebView, but I want to block certain calls made by the website (such as some of my analytics) to speed up the load within the WebView. If I connect the device to a proxy (I've been using Charles Proxy) I can see these requests going out, just as I would expect them to. However, for whatever reason, 

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

Is not capturing the requests I'm looking for. In fact, webView:(UIWebView *)... is only firing on about a third of the calls that I see going out over the proxy.

Does anyone know why that might be? Or have any idea what I can do to intercept all of the calls made by a UIWebView?

Thank you

You will not get delegate calls for all requests from the web view (for example, resource requests, such as JavaScript and images).

To have a precise control over all requests, you will need to implement a NSURLProtocol in which you can decide what request to allow and what to block.
