title: Refresh iOS UIDatePicker whenever a view is reloaded or after period of time?
body: <p>I've got an iPhone app that I've made, that on one view has a UIDatePicker.</p>
  
  <p>When you initially launch the app - and the view first loads; inside the viewDidLoad I have the UIDatePicker get set to the current date/time.  It works fine.</p>
  
  <p>Now if the user minimizes the app and does other things (but does not kill the app) and then goes back to the app, the date/time does not update when you go back to that view.</p>
  
  <p>I'm wondering how I would go about making it 'refresh' that UIDatePicker any time the view is loaded (for example, when you go back to it after it's already been opened but is sitting in the background).</p>
  
  <p>Any thoughts?</p>
  
  <p>If there's no quick/easy way - I also considered creating a time related variable when the UIDatePicker loads initially - then when it is reloaded having it check to see if more than 10 minutes had passed since the last view.  If so, then it would set the UIDatePicker to current date/time.</p>
  
  <p>Any ideas?</p>
