title: What is the simplest way to display a NSString value?
body: <p>I'm trying to display a variable value to the IPhone screen. I'm using XCode and the simulator. I can use <code>NSLog</code> to print the output to the debug screen but I'm at a loss to understand how to get the same output to the actual screen.</p>
  <p>What I have now in <code>main.m</code>.</p>
  <pre><code>NSString *testvalue = @&quot;Test&quot;;
  
  NSLog(@&quot;Output %@\n&quot;, testvalue);
  </code></pre>
  <p>My understanding is that all display operations occur in <code>viewcontroller.m</code> but from what I have been reading ,it seems that the action is not as simple as creating debug output.</p>
