Reload View only when application is opened Again
<p>My application has tab bar with one of the tabs having a segmented control on navigation bar.
Based on segment clicked different view  is displayed using a url.
I am calling the url in  viewdidload method.I do not want to use viewwillAppear to call the url as it will be called each time the view is displayed.
I only want to call the url again whenever user closes the application and comes back.</p>

<p>Whats the best way to do this.Should I remove the view controller from and reload it again once the application is opened.</p>
