Question

I have a UIWebView that loads a local HTML file from the resources folder.
Now, this HTML file has Javascript inside it.

My question is, is there a way to pass an XCode variable to the HTML file that gets loaded inside the UIWebView which I can pass to the Javascript function in the HTML.

Thanks a lot for any help or suggestion.

You can construct a Javascript string then pass into -stringByEvaluatingJavaScriptFromString:, e.g.

NSInteger u = get_integer_from_user();
NSString* script = [NSString stringWithFormat:@"call_your_function(%d);", u];
[webView stringByEvaluatingJavaScriptFromString:script];
