title: Call Objective C method from JavaScript (React Native)
body: <p>I have read over the docs time and time again and can only seem to work out how to send data from Objective C to JavaScript (React Native) via props.</p>
  
  <p>What I want to do though is to trigger and Objective C Method from JavaScript (React Native) at a certain point. A simple example that triggers a method that prints "Hello World" to the console will be enough for me to see how it works.</p>
