How to hide title/message frame in a UIAlertController?

Question

When I create a UIAlertController with this code I don't have the title spacing.

[UIAlertController alertControllerWithTitle:nil
                                    message:nil
                             preferredStyle:UIAlertControllerStyleActionSheet];

Are you passing in nil for the title and message or empty strings?

Update Swift 4:

let alert = UIAlertController(title: nil, message: nil, preferredStyle: UIAlertControllerStyle.actionSheet)

Just need to pass nil to title and message params.

If you want to change in run time depending on a certain case just write:

actionController.title = nil
actionController.message = nil

In swift 2.2, you can use code below and I have also changed the color of signout action button

        let actionSheet: UIAlertController = UIAlertController(title: nil, message: nil, preferredStyle: .ActionSheet)

    self.presentViewController(actionSheet, animated: true, completion: nil)

    let settingsActionButton: UIAlertAction = UIAlertAction(title: "Settings", style: .Cancel) { action -> Void in
        print("Settings Tapped")
    }

    reportActionSheet.addAction(settingsActionButton)

    let signOutActionButton: UIAlertAction = UIAlertAction(title: "Signout", style: .Default)
    { action -> Void in
        //Clear All Method
        print("Signout Tapped")

    }

    signOutActionButton.setValue(UIColor.redColor(), forKey: "titleTextColor")

    actionSheet.addAction(signOutActionButton)

    let cancelActionButton: UIAlertAction = UIAlertAction(title: "Cancel", style: .Cancel) { action -> Void in
        print("Cancel Tapped")
    }

    reportActionSheet.addAction(cancelActionButton)
