Swift 3如何以模态方式呈现splitview控制器？

func presentSplitViewControllerModally() {
    let splitViewController = UISplitViewController()
    splitViewController.delegate = self
    
    // 设置split view控制器的各个视图控制器
    
    present(splitViewController, animated: true, completion: nil)
}

let masterViewController = UIViewController()
let detailViewController = UIViewController()

splitViewController.viewControllers = [masterViewController, detailViewController]

func splitViewController(_ splitViewController: UISplitViewController, collapseSecondary secondaryViewController: UIViewController, onto primaryViewController: UIViewController) -> Bool {
    return true
}
