我是新的 iOS 编程，现在对使用MaterialComponentsgoogle 提供的程序很着迷。现在我在名为Dialog.

当我在该弹出视图之外触摸该视图时，该视图已在屏幕上弹出，然后该视图已被关闭。我不希望在我的应用程序中发生这种情况。

我不希望用户单击外部弹出视图来关闭该弹出视图。我想要什么，我只希望用户单击我为用户选择提供的操作按钮，然后仅在单击该操作按钮时视图应该被关闭。

真的很高兴你能帮忙。

MDCAlertController继承自UIViewController。

因此，为了限制用户点击外部MDCAlertController，您必须访问其名为的属性view，然后superview?.subviews[0].isUserInteractionEnabled = false

我已经使用 MDCAlertController 完成了一个示例

let alert = MDCAlertController(title: title, message: message)

    alert.buttonTitleColor = UIColor(red:0.03, green:0.62, blue:0.09, alpha:1.0)

    //MDCAlertControllerThemer.applyScheme(alertScheme, to: alert)
    let okayAction = MDCAlertAction(title: "Okay") { (action) in

        print("User click okay")

    }
    let cancelAction = MDCAlertAction(title: "Cancel", handler: nil)
    alert.addAction(okayAction)
    alert.addAction(cancelAction)

    self.present(alert, animated: true, completion: {

        // When the Dialog view has pop up on screen then just put this line of code when Dialog view has completed pop up.
        alert.view.superview?.subviews[0].isUserInteractionEnabled = false
    })

用这个。

let alert = MDCAlertController(title: title, message: message)

alert.mdc_dialogPresentationController.dismissOnBackgroundTap = false
