title: iPhone UIToolbar with UIActionSheet style buttons
body: <p>I have an main window containing a UIToolBarController. In my first tab, I load a UIViewController, where I have an MKMapView. Above the map, I would like a toolbar like on the screenshot below (basically, instead of their UITableView I have an MKMapView...):</p>
  
  <p><img src="https://i.stack.imgur.com/stekM.jpg" alt="Clock app with top UIToolBar and UIActionSheet style buttons"></p>
  
  <p>I'd like to know how I can make this big toolbar on top, and would like to add just une UIActionSheet style button ("Start" in green, and when clicked switch to red "Stop").</p>
  
  <p>Thanks!</p>
  
  <p>PS: The app from the screenshot is Clock if you want to try.</p>
