Answer 1

I guess using delegate is the only (one or two) methodology you can use in iOS WebView. But there are several wrappers that may help you easy out.

1. EasyJSWebView - This replicates the development experience as in Android. In Android, you can simply use the addJavascriptInterface() method in WebView to bridge the Javascript to Java. EasyJSWebView provides both sync-style and async-style for getting the return value from Objective-C methods.

2. WebViewJavascriptBridge - The code may look a little bit like socket programming. You can pass data to and fro between the "server" in Objective-C and the "client" in Javascript.

3. GAJavaScript - This may provide a better DOM manipulation experience.

Take a look at all of them and choose one that fits your need.
