Go to simulated metrics and you should find it. Here is an image of where it is. Note that popover is available only in iPad not in iphone through simulator.
Edit:
Here is sample code for using a button and action method to create a popover:
You will need to declare a popoverController property:
@property (nonatomic, strong) UIPopoverController* buttonPopoverController;
Then your button action can look something like this:
- (void) buttonTapped:(UIButton*) sender
{
ContentViewController* contentVC = [[ContentViewController alloc] init];
self.buttonPopoverController = [[UIPopoverController alloc]
initWithContentViewController:contentVC];
self.buttonPopoverController.delegate = self;
//only required if using delegate methods
[self.buttonPopoverController presentPopoverFromRect:sender.frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
}
The ContentViewController is whichever view controller you are intending to segue to. If it is configured using a storyboard scene, you may want to do something like this when you create it:
UIStoryboard *storyboard = self.storyboard;
ContentViewController* contentVC =
[storyboard instantiateViewControllerWithIdentifier:@"ContentViewController"];
You can set the storyboard identifier using the Identity Inspector when you have the relevant view controller selected in the storyboard.
