Javascript in UIWebView callback to C/Objective-C

Question

Is there a way to get a callback to objective-c when a certain event has been detected in a UIWebView? Can Javascript send a callback to Objective-C?

Answer 1

In your UIWebView delegate, provide an implementation for webView:ShouldStartLoadWithRequest:navigationType:

In your HTML or Javascript files, add functions that send URLs to a custom scheme (for readability purposes, the custom scheme isn't required). All the URLs sent will be passed to your Objective-C method implementation, and then you can do what you'd like.
