当我在应用程序未完全打开阶段时点击推送通知警报时,我遇到了特定 View Controller 未移动的问题。
这是我的代码:
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
/*
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()
}
}
}
当应用程序处于事件状态时,我可以获得通知并点击以移动特定的 VC。请帮助我我所缺少的。
最佳答案

简单地实现以下函数,当用户点击通知时将调用该函数。
在 AppDelegate 中:
// This method is called when user clicked on the notification
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void)
{
// Do whatever you want when the user tapped on a notification
// If you are waiting for specific data from the notification
// (e.g., key: "target" and associated with "value"),
// you can capture it as follows then do the navigation:
// You may print `userInfo` dictionary, to see all data received with the notification.
let userInfo = response.notification.request.content.userInfo
if let targetValue = userInfo["target"] as? String, targetValue == "value"
{
coordinateToSomeVC()
}
completionHandler()
}
private func coordinateToSomeVC()
{
guard let window = UIApplication.shared.keyWindow else { return }
let storyboard = UIStoryboard(name: "YourStoryboard", bundle: nil)
let yourVC = storyboard.instantiateViewController(identifier: "yourVCIdentifier")
let navController = UINavigationController(rootViewController: yourVC)
navController.modalPresentationStyle = .fullScreen
// you can assign your vc directly or push it in navigation stack as follows:
window.rootViewController = navController
window.makeKeyAndVisible()
}
注意事项:
如果您根据通知导航到特定的 Controller ,您应该关心如何从该 Controller 导航回来,因为现在您的堆栈中没有 Controller 。您必须实例化您将返回的 Controller 。在我的例子中,当用户点击返回时,我实例化家庭 Controller 并再次将其设置为应用程序根目录,因为应用程序将正常启动。
