Receive message from JavaScript WebView in Objective-C

Question

I have a WebView with a JavaScript function loadStuff , that makes some ajax calls.

In my AppDelegate, I've managed to to use WebView's stringByEvaluatingJavaScriptFromString to execute loadStuff.

Now my problem is I want to execute some Objective-C code once the JavaScript ajax stuff is done. How can my JavaScript notify back the native code?

如果您有权访问AJAX成功处理程序，则可以强制Webview从中打开一些伪造的url，然后从委托的shouldStartLoadWithRequest中进行处理。
