title: Can I create App Delegate file in my project?
body: <p>I have my ipad code created programmatically not using nib.I converted my ipad app to universal app as follows:</p>
  
  <blockquote>
    <p>Choose the project target(the blue one on the sidebar). Summary -> iOS
    Application Target -> set Devices to Universal.</p>
  </blockquote>
  
  <p>Now I want to launch different app delegate for iphone and different app delegate for ipad.There is already one app delegate for ipad, now I want to create different app delegate for iphone so that in main.m I can launch different app delegate based on device(ipad &amp; iphone).So my question is, can I create different app delegate, if yes then how?</p>
