title: Best Method to Show a Popup Transparent Window on iPhone?
body: <p>I'm building an iOS 6 iPhone app in Xcode 4.6 and am wondering about the best way to achieve the following type of popup window:</p>
  
  <p><img src="https://i.stack.imgur.com/zyoF1.png" alt="PopoverScreenshot"></p>
  
  <p>Specifically, the iPhone screenshot on the right, where, if a user taps on a face or UIView in the main window, a partially transparent popover appears with more detailed information -- such as a portrait photo and textual data -- but the original view (a photo collection here) remains visible, and the timers/counters continue ticking down in that view.</p>
  
  <p>I thought this would be a possible solution <a href="https://stackoverflow.com/questions/915318/iphone-modal-view-smaller-that-the-screen">iPhone Modal View Smaller that the screen</a> but it doesn't work for me.  Not shown above is a cancel button that I am also planning to put in the popover, so that the user can return to the view underneath. When the timer expires, the detailed view also disappears.</p>
  
  <p>Should I use presentModalViewController and the presenter/presented scheme, or use a parent-child-view relationship with a storyboard segue, or should I use loadNibNamed, or some kind of hack to overcome the iPhone's limitation of displaying a non-full-screen modal view?  It'll cover most of the screen but I want to make sure the view underneath is visible and still active, since it provides information to the user that isn't in the popover (timer, etc.). The user won't need to interact with the screen below, but I'd like it to be partially visible.</p>
  
  <p>I designed the popup view as a separate viewcontroller in my main storyboard, not as a xib file. The connections and outlets are formed from interface builder to my code, called ProfileViewController.</p>
  
  <p>WARNING: My terminology may be incorrect and inaccurate.  The popup or popover can be a UIView, UIViewController, UIWindow, or whatever works best programatically to solve the problem.  I'm not tied to it being a certain widget type, as long as the functionality mirrors what I'm seeking.</p>
  
  <p>Thanks in advance for your suggestions!</p>
