With UIAlertController, action sheets like the deprecated UIActionSheet are created with the same API as you use for AlertViews.

Simple Action Sheet with two buttons

Swift

let alertController = UIAlertController(title: "Demo", message: "A demo with two buttons", preferredStyle: UIAlertControllerStyle.actionSheet)

Objective-C

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Demo" message:@"A demo with two buttons" preferredStyle:UIAlertControllerStyleActionSheet];

Create the buttons “Cancel” and “Okay”

Swift

let cancelAction = UIAlertAction(title: "Cancel", style: .cancel) { (result : UIAlertAction) -> Void in
    //action when pressed button
}
let okAction = UIAlertAction(title: "Okay", style: .default) { (result : UIAlertAction) -> Void in
    //action when pressed button
}

Objective-C

UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction * action) {
        //action when pressed button
    }];

UIAlertAction * okAction = [UIAlertAction actionWithTitle:@"Okay" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
        //action when pressed button
    }];

And add them to the action sheet:

Swift

alertController.addAction(cancelAction)
alertController.addAction(okAction)

Objective-C

[alertController addAction:cancelAction];
[alertController addAction:okAction];

Now present the UIAlertController:

Swift

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

Objective-C
