有没有办法不分配 UIModalTransitionStyle?

Is there any way to assign no UIModalTransitionStyle?

我知道 UIModalTransitionStyle 有四种类型,但我不想使用其中任何一种。

但是,此代码不起作用:

@IBAction func button(sender: AnyObject) {

    let modalView = ViewController()

    let storyboard = UIStoryboard(name: "Universal", bundle: nil)
    let vc = storyboard.instantiateViewControllerWithIdentifier("ViewController") as UIViewController
    modalView.modalTransitionStyle = nil // Error: type 'UIModalTransitionStyle' does not conform to protocol 'NilLiteralConvertible'

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

}

每当我不指定 modalTransitionStyle 时,编译器将从 UIViewController.

的 Storyboard 文档中获取 modalTransitionStyle

如何设置不modalTransitionStyle

如果您不想要过渡,您应该在展示新视图控制器时将 animated 属性 设置为 false

self.presentViewController(vc, animated: false, completion: nil)
