title: How to take multiple photos in a sequence (1s delay each), using Swift on iOS8.1?
body: <p>I am trying to take few photos after a single user click on a Camera preview so I can present them and user can pick one that was timed best or use all in a "film strip" mode. The expected user experience is: "I open a camera, take a picture and then I see 5 pictures taken second by second. I do not have to press the 'take picture' button 5 times, one is just enough to start the sequence".</p>
  
  <p>I am new to iOS and Swift and I base my work on a 'Swift Recipes' book (<a href="https://www.safaribooksonline.com/library/view/ios-8-swift/9781491908969/" rel="noreferrer">https://www.safaribooksonline.com/library/view/ios-8-swift/9781491908969/</a>). </p>
  
  <p>The source code to take a single photo is:</p>
  
  <pre><code>controller = UIImagePickerController()
      if let theController = controller{
          theController.sourceType = .Camera
          theController.mediaTypes = [kUTTypeImage as NSString]
          theController.allowsEditing = true
          theController.delegate = self
          presentViewController(theController, animated: true, completion: nil)
      }
  </code></pre>
  
  <p>plus the relevant image handling (via func imagePickerController). I tried playing with the controller objecct above, but miserably failed :( I believe that this is not the right way to get what I look for, but I struggle to find the right one. Any help will be appreciated.</p>
