title: button not displaying correctly in iphone simulator in Xcode 4.6.2
body: <p>My application view looks like this:</p>
  
  <p><img src="https://i.stack.imgur.com/6fHLp.png" alt="view editor/storyboard"></p>
  
  <p>But when I run simulator, it displays like this for some reason:</p>
  
  <p><img src="https://i.stack.imgur.com/qaZdO.png" alt="simulator"></p>
  
  <p>As you can see the three <code>UIButton</code>s in the last row are not displaying correctly. I am not sure what exactly is going on here.</p>
  
  <p>What I am doing:</p>
  
  <ul>
  <li><p>I am creating an RPN calculator by following the CS193 Stanford iTunes U course. The buttons I am using are plain <code>UIButton</code>s, they are linked to the controller as <code>action</code>s.</p></li>
  <li><p>I am not creating these buttons through code, they are simply dragged into the view.</p></li>
  <li><p>I changed the text displaying on the button by double clicking on them. (I am not sure if this will help but I just provided this information in case it's helpful)</p></li>
  <li><p>It seems to be happening only to the buttons at the last row, since if I drag another button from the top to the bottom, the text will disappear as well.</p></li>
  <li><p>My thought: could it be related to the screen size difference of iPhone 5 and iPhone 4/4s? It seems that the storyboard gives me a screen of the size of an iPhone 5, but simulator is simulating an iPhone 4 sized screen.</p></li>
  <li><p>This was not happening before until I decided to resize the enter button to twice the size it is right now. After that happened, I resized enter button to it's original size, which is what is displaying in the pictures below, but that did not fix the problem.</p></li>
  <li><p>I tried changing the storyboard to 3.5 form factor, but that didn't fix the problem. (In fact, I tried all the combinations, including the ones that shouldn't work, i.e. 3.5 storyboard + 4inch retina simulator, etc.) and none of them is displaying correctly.</p></li>
  </ul>
  
  <p>Thanks in advance!</p>
  
  <p>PS: I am sorry but for people who are <strong><em>still</em></strong> down voting, would you mind read my question first? I already updated this post with all the information that I can give. The view is not built with code so I am not sure if I can provide any source code on the view part.</p>
