Here's a simplified version of @jasonjwwilliams answer.

#define JAVASCRIPT_TEST_VARIBLE @"window.IOSVariable"
#define JAVASCRIPT_TEST_FUNCTION @"IOSFunction"
#define LOAD_COMPLETED @"loaded"

// Put this in your init method
// In Javascript, first define the function, then attach it as a listener.
_javascriptListener = [NSString stringWithFormat:
    @"function %@() {\
         %@ = '%@';\
    };\
    window.addEventListener(\"load\", %@, false);",
        JAVASCRIPT_TEST_FUNCTION, JAVASCRIPT_TEST_VARIBLE, LOAD_COMPLETED, JAVASCRIPT_TEST_FUNCTION];

// Then use this:

- (void)webViewDidFinishLoad:(UIWebView *)webView;
{
    // Only want to attach the listener and function once.
    if (_javascriptListener) {
        [_webView stringByEvaluatingJavaScriptFromString:_javascriptListener];
        _javascriptListener = nil;
    }

    if ([[webView stringByEvaluatingJavaScriptFromString:JAVASCRIPT_TEST_VARIBLE] isEqualToString:LOAD_COMPLETED]) {
        NSLog(@"UIWebView object has fully loaded.");
    }
}
