title: How to set a default value to a UITextField when the application is loaded?
body: <p>I'm a Objective-C newbie and I'm currently trying to build an app which has a <code>UITextField</code> (called "initial_dose") and I'm wondering how can I set a default value which will be visible straight after the application is loaded.</p>
  
  <p>I kind of know how to set the value but not sure where I need to call this?</p>
  
  <pre><code>initial_dose.text = "@myInitialVal";
  </code></pre>
  
  <p>Thanks a lot in advance!</p>
