title: Objective-C: Create custom UIPopoverController like in iCalendar App
body: <p>Is it possible to create a custom UIPopoverController? Can you give me some suggestions (Links, tutorial...)?</p>
  
  <p>I would create a sort of popover like the one in <strong>iPad</strong> calendar application. When the popover appears (in view mode), it has no border (white background). Then, when you enter the modify mode (for example through a modify button), the popover chage its appereance (the border color and so on).</p>
  
  <p>Thank you in advance. Regards.</p>
