Presenting modal in iOS 13 fullscreen

Question

In iOS 13 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 dis

Answer 1

Here's my version of fix in ObjectiveC using Categories. With this approach you'll have default UIModalPresentationStyleFullScreen behaviour until another one explicitly set.

#import "UIViewController+Presentation.h"
#import "objc/runtime.h"

@implementation UIViewController (Presentation)

- (void)setModalPresentationStyle:(UIModalPresentationStyle)modalPresentationStyle {
    [self setPrivateModalPresentationStyle:modalPresentationStyle];
}

-(UIModalPresentationStyle)modalPresentationStyle {
    UIModalPresentationStyle style = [self privateModalPresentationStyle];
    if (style == NSNotFound) {
        return UIModalPresentationFullScreen;
    }
    return style;
}

- (void)setPrivateModalPresentationStyle:(UIModalPresentationStyle)modalPresentationStyle {
    NSNumber *styleNumber = [NSNumber numberWithInteger:modalPresentationStyle];
     objc_setAssociatedObject(self, @selector(privateModalPresentationStyle), styleNumber, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
}

- (UIModalPresentationStyle)privateModalPresentationStyle {
    NSNumber *styleNumber = objc_getAssociatedObject(self, @selector(privateModalPresentationStyle));
    if (styleNumber == nil) {
        return NSNotFound;
    }
    return styleNumber.integerValue;
}

@end

Latest for iOS 13 and Swift 5.x

let vc = ViewController(nibName: "ViewController", bundle: nil)

vc.modalPresentationStyle = .fullScreen

self.present(vc, animated: true, completion: nil)

Answer 3

The above answers and suggestions are right, below is another version, and efficient way using programmatically.

#1 Created a UIView Extension

#2 Created a Method ()

//#1
extension UIViewController {

//#2
func presentLocal(_ viewControllerToPresent: UIViewController, animated flag: 
Bool, completion: (() -> Void)? = nil) {

//Reusing below 2 lines :-)
viewControllerToPresent.modalPresentationStyle = .overCurrentContext
self.present(viewControllerToPresent, animated: flag, completion: completion)

  }
}

Invoking as below

let vc = MyViewController()
let nc = UINavigationController(rootViewController: vc)
sourceView.presentLocal(nc, animated: true, completion: nil)

OR

let vc = MyViewController()
sourceView.presentLocal(vc, animated: true, completion: nil)

Answer 4

let Obj = MtViewController()
Obj.modalPresentationStyle = .overFullScreen
self.present(Obj, animated: true, completion: nil)

// if you want to disable swipe to dismiss on it, add line

Obj.isModalInPresentation = true

Answer 5

The simplest solution that worked for me.

viewController.modalPresentationStyle = .fullScreen

Answer 6

As a hint: If you call present to a ViewController which is embedded inside a NavigationController you have to set the NavigationController to .fullScreen and not the VC.

You can do this like @davidbates or you do it programmatically (like @pascalbros).

The same applies to the UITabViewController

An example scenario for NavigationController:

    //BaseNavigationController: UINavigationController {}
    let baseNavigationController = storyboard!.instantiateViewController(withIdentifier: "BaseNavigationController")
    var navigationController = UINavigationController(rootViewController: baseNavigationController)
    navigationController.modalPresentationStyle = .fullScreen
    navigationController.topViewController as? LoginViewController
    self.present(navigationViewController, animated: true, completion: nil)
