我已在我的应用中添加了推送通知。它们可以在用户按下时打开特定的屏幕。当应用程序完全关闭时,以及在前台打开应用程序时,它们都可以正常工作。但是,当它处于背景中时,通过按推(而不是所需的推)来打开第一个屏幕。
[在这里,在AppDelegate中,当应用程序关闭时,我使用push:
let pushManager = PushNotificationManager(userID: "UserID")
pushManager.registerForPushNotifications()
let notificationOption = launchOptions?[.remoteNotification]
if let notification = notificationOption as? [String: AnyObject],
let aps = notification["aps"] as? [String: AnyObject] {
print(aps)
let storyboard = UIStoryboard(name: "Invoice", bundle: nil)
guard let returnPage = storyboard.instantiateViewController(withIdentifier:
"\(InvoiceViewController.self)") as? InvoiceViewController else { return true }
if let navBar = self.window?.rootViewController as? UINavigationController {
navBar.pushViewController(returnPage, animated: true)
}
}
[这里,也是在AppDelegate中,当应用程序打开时,我使用push进行操作:
func application(
_ application: UIApplication,
didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler:
@escaping (UIBackgroundFetchResult) -> Void
) {
guard let aps = userInfo["aps"] as? [String: AnyObject] else {
completionHandler(.failed)
return
}
let storyboard = UIStoryboard(name: "Invoice", bundle: nil)
guard let returnPage = storyboard.instantiateViewController(withIdentifier:
"\(InvoiceViewController.self)") as? InvoiceViewController else { return }
if let navBar = self.window?.rootViewController as? UINavigationController {
navBar.pushViewController(returnPage, animated: true)
}
print(aps)
}
您应该使用以下代码来处理用户对推送通知的响应。
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: @escaping () -> Void) {
// handle it here
}
这是UNUserNotificationCenterDelegate
的一部分,专门用于用户响应,因此您也不必关心应用程序的状态。希望对您有所帮助。
