Presenting modal in iOS 13 fullscreen

Question

In iOS 13 Beta 1 there is a new behaviour for modal view controller when being presented. Now it's not fullscreen by default and when I try to slide down, the app just dismiss the View Controller automatically.

How can I prevent this behaviour and get back to the old good fullscreen modal vc?

Thanks

Answer 1

With iOS 13, as stated in the Platforms State of the Union during the WWDC 2019, Apple introduced a new default card presentation. In order to force the fullscreen you have to specify it explicitly with:

let vc = UIViewController()
vc.modalPresentationStyle = .fullScreen
self.present(vc, animated: true, completion: nil)

Answer 2

I add an information that could be useful for someone. If you have any storyboard segue, to go back to the old style, you need to set the kind property to Present Modally and the Presentation property to Full Screen.

Answer 3

In Objective-C two ways I have found.

I notice that the two enum modalPresentationStyles are all less than zero

UIModalPresentationNone API_AVAILABLE(ios(7.0)) = -1,

UIModalPresentationAutomatic API_AVAILABLE(ios(13.0)) = -2,

• override your base ViewController method （I suggest）

- (void)presentViewController:(UIViewController *)viewControllerToPresent animated:(BOOL)flag completion:(void (^)(void))completion
{
    if (viewControllerToPresent.modalPresentationStyle < 0){
        viewControllerToPresent.modalPresentationStyle = UIModalPresentationFullScreen;
    }
    [super presentViewController:viewControllerToPresent animated:flag completion:completion];
}
