title: iOS JavaScript bridge
body: <p>I'm working on an app where I'm going to use both HTML5 in UIWebView and native iOS framework together. I know that I can implement communication between JavaScript and Objective-C. Are there any libraries that simplify implementing this communication? I know that there are several libraries to create native iOS apps in HTML5 and javascript (for example AppMobi, PhoneGap), but I'm not sure if there is a library to help create native iOS apps with heavy JavaScript usage. I need to:</p>
  
  <ol>
  <li>Execute JS methods from Objective-C</li>
  <li>Execute Objective-C methods from JS</li>
  <li>Listen to native JS events from Objective-C (for example DOM ready event)</li>
  </ol>
