Ios 为什么在swift中点击推送通知并移动ViewController时状态栏消失

上面的代码是获取推送通知数据，并在用户点击时发送给相关的视图控制器。但我发现当视图控制器打开时，状态栏丢失。请告诉我如何修理，谢谢

乍一看（在没有实际验证代码的情况下），我怀疑罪魁祸首是：

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {

    /* */
    self.window = UIWindow(frame: UIScreen.main.bounds)
    self.window?.rootViewController = UIViewController()
    self.window?.windowLevel = UIWindowLevelAlert + 1
    self.window?.makeKeyAndVisible()

    /*

    fetch and add push notification data

     */
    goAnotherVC()
}

func goAnotherVC() {
    if (application.applicationState == UIApplicationState.active) {
        /* active stage is working */ 
    } else if (application.applicationState == UIApplicationState.inactive || application.applicationState == UIApplicationState.background) {
        if (type == "1" || type == "2") {
            let storyboard: UIStoryboard = UIStoryboard(name: "MyAppointments", bundle: nil)
            let apptVC = storyboard.instantiateViewController(withIdentifier: "NotificationDetailViewController") as! NotificationDetailViewController
            let navigationController = UINavigationController.init(rootViewController: apptVC)
            self.window?.rootViewController = navigationController
            self.window?.makeKeyAndVisible()
        } else if (type == "3") {
            let storyboard: UIStoryboard = UIStoryboard(name: "MyAppointments", bundle: nil)
            let apptVC = storyboard.instantiateViewController(withIdentifier: "NotificationDetailViewController") as! NotificationDetailViewController
            let navigationController = UINavigationController.init(rootViewController: apptVC)
            self.window?.rootViewController = navigationController
            self.window?.makeKeyAndVisible()
        } else if (type == "4") {
            let storyboard: UIStoryboard = UIStoryboard(name: "Enquiry", bundle: nil)
            let enqVC = storyboard.instantiateViewController(withIdentifier: "EnquiryDetailViewController") as! EnquiryDetailViewController
            let navigationController = UINavigationController.init(rootViewController: enqVC)
            self.window?.rootViewController = navigationController
            self.window?.makeKeyAndVisible()
        }
    }
}

您正在将窗口设置为覆盖视图的全部边界。要查看这是否是问题所在，只需将该行更改为以下内容：

self.window = UIWindow(frame: UIScreen.main.bounds)

---

看看问题是否消失了。在我的代码中，我只是简单地更改了窗口的顶部位置以允许状态栏。

您是否尝试过此设置，方法是-首选StatusBarHidden为not working，尽管它看起来不如占用更多的空间，因为导航栏的高度比正常值大。

var rect = UIScreen.main.bounds
rect.origin.y += 20
self.window = UIWindow(frame: rect)
