iOS UIWebView URL拦截 about technotes

WebViewProxy.
Proxy requests for a web views, easily and without mucking around with NSURLProtocol.

Works on iOS and OSX.

Responses to intercepted requests may be served either synchronously or asynchronously - this stands in contrast to the UIWebViewDelegate method -(NSCachedURLResponse *)cachedResponseForRequest:url:host:path:, which may only intercept requests and serve responses synchronously (making it impossible to e.g. proxy requests through to the network without blocking on the network request).

If you like WebViewProxy you should also check out WebViewJavascriptBridge.
