您需要添加敲击手势在视图中viewDidLoad像这样

let tapGesture:UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(self.viewTapped(_:))) 
self.view.addGestureRecognizer(tapGesture) 

现在，在您ViewController

func viewTapped(sender: UITapGestureRecognizer){ 
    self.dismissViewControllerAnimated(true, completion: nil) 
}
