SYPopoverController

UIPresentationController subclass to show a UIViewController centered on-screen, with the desired preferredContentSize.

PS: sorry, not the best name, but SYPopupController was already taken.

Sample code

// 1. The controllers your want to present in the popover
UINavigationController *navController = [[UINavigationController alloc] init];
UIViewController *viewController = [[UIViewController alloc] init];
[navController setViewControllers:@[viewController]];

// 2. Prepare the navigationController to use SYPopoverController
[navController setModalPresentationStyle:UIModalPresentationCustom];
[navController setTransitioningDelegate:[SYPopoverTransitioningDelegate shared]];

// 3. Present
[self presentViewController:navController animated:YES completion:nil];

// (Optional) 4. Access the popoverController to use the background you wish
// Here we use a semi-transparent white color
SYPopoverController *popoverController = (SYPopoverController *)navController.presentationController;
[popoverController.backgroundView setBackgroundColor:[UIColor colorWithWhite:1. alpha:0.6]];

// Alternative to 2+3: use the helper method
[self sy_presentPopover:navController animated:YES completion:nil];

Customizations

Background

By default there is no background. You have two options to change this behaviour:

• Implement popoverControllerBackgroundColor: from SYPopoverContentViewDelegate in presented view controllers

• Access the background view using the following code, and change its background color or add a subview

     [(SYPopoverController *)myViewController.presentationController backgroundView]
  

Dismiss

By default when the user taps the background of the popoverController it is dismissed. You can override this behaviour by conforming to SYPopoverContentViewDelegate and implementing popoverControllerShouldDismissOnBackgroundTap:
