Push notification 控制在SWIFT中接收推送通知后加载哪个视图控制器
一旦我收到推送通知并滑动打开它，它只会打开我的应用程序，而不是我想要的VC 所以我的问题是如何加载我想要的VC？我知道如果应用程序已打开，我会将VC移到Push notification 控制在SWIFT中接收推送通知后加载哪个视图控制器,push-notification,apple-push-notifications,appdelegate,Push Notification,Apple Push Notifications,Appdelegate,一旦我收到推送通知并滑动打开它，它只会打开我的应用程序，而不是我想要的VC 所以我的问题是如何加载我想要的VC？我知道如果应用程序已打开，我会将VC移到DidReceivereMotentification中的另一个，但如果应用程序未打开，我该如何操作？或者它是否处于后台模式 另外，我有两个不同的推送通知，因此我需要它来移动两个不同VCs中的一个。如何区分不同推送动作之间的差异 谢谢。运行应用程序时，您正在使用选项调用ApplicationIDLaunch： UIApplication.shar
DidReceivereMotentification谢谢。运行应用程序时，您正在使用选项调用ApplicationIDLaunch：
UIApplication.sharedApplication().registerUserNotificationSettings ( UIUserNotificationSettings(forTypes: (UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound), categories: nil))
if( launchOptions != nil){
var notificationDict: AnyObject? = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey]
if(notificationDict != nil){
handleNotification(notificationDict! as! [NSObject : AnyObject])
}
}
if let notification = launchOptions?[.remoteNotification] as? [AnyHashable : Any] {
notificationsUserInfo = notification as [AnyHashable : Any]
serveNotifications = true
}
let notificationType = userInfo["aps"]!["alert"]!!["some-key-I-Need"]! as! String
var storyboard = UIStoryboard(name: "Main", bundle: nil)
let mainViewController = storyboard.instantiateInitialViewController() as! MyViewController
self.window?.rootViewController = mainViewController
除了@NickCatib的答案外，要了解您在应用程序运行时是否收到通知，如果收到通知，您需要在前台或后台的AppDelegate中使用此方法：
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
// You can determine your application state by
if UIApplication.sharedApplication().applicationState == UIApplicationState.Active {
// Do something you want when the app is active
} else {
// Do something else when your app is in the background
}
}
为Swift 4.2更新 如前所述，您希望在ApplicationIDLaunchWithOptions中注册远程通知：
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
let pushSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
UIApplication.shared.registerUserNotificationSettings(pushSettings)
UIApplication.shared.registerForRemoteNotifications()
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
let notif = JSON(userInfo) // SwiftyJSON required
if notif["callback"]["type"] != nil {
NotificationCenter.default.post(name: Notification.Name(rawValue: "myNotif"), object: nil)
// This is where you read your JSON to know what kind of notification you received
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
NotificationCenter.default.addObserver(self, selector: #selector(self.catchIt), name: NSNotification.Name(rawValue: "myNotif"), object: nil)
}
func catchIt(_ userInfo: Notification){
let prefs: UserDefaults = UserDefaults.standard
prefs.removeObject(forKey: "startUpNotif")
if userInfo.userInfo?["userInfo"] != nil{
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc: RedirectAppInactiveVC = storyboard.instantiateViewController(withIdentifier: "RedirectAppInactiveVC") as! RedirectAppInactiveVC
self.navigationController?.pushViewController(vc, animated: true)
} else {
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc: RedirectAppActiveVC = storyboard.instantiateViewController(withIdentifier: "RedirectAppActiveVC") as! RedirectAppActiveVC
self.navigationController?.pushViewController(vc, animated: true)
}
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillAppear(animated)
NotificationCenter.default.removeObserver(self)
}
let prefs: UserDefaults = UserDefaults.standard
if let remoteNotification = launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] as? NSDictionary {
prefs.set(remoteNotification as! [AnyHashable: Any], forKey: "startUpNotif")
prefs.synchronize()
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
let prefs: UserDefaults = UserDefaults.standard
if prefs.value(forKey: "startUpNotif") != nil {
let userInfo: [AnyHashable: Any] = ["inactive": "inactive"]
NotificationCenter.default.post(name: Notification.Name(rawValue: "myNotif"), object: nil, userInfo: userInfo as [AnyHashable: Any])
}
}
这里的这些例子说明了如何简单地实现它。对于更大的项目，您将得到更复杂的体系结构，例如内部使用类似机制的协调器 我发现上面所有的答案都非常有用。然而，当应用程序被停用时，投票最多的人对我来说并不起作用。后来，a尝试实现@NickCatib和@TheFredeElement组合的答案，它们在执行情节提要时生成了一个错误。InstanceInitialViewController（）-“无法强制转换类型为'UINavigationController'的值”。我发现发生这种情况是因为我有一个脚本文件，其中NavController作为rootViewController。为了解决这个问题，我创建了一个新的导航控制器，解决了一个问题：我丢失了应用程序的正确导航，视图甚至没有显示后退按钮。我的问题的答案是使用@NickCatib和@thefreedelement answers，但使用标识符实例化视图并将其推送，使用rootViewController作为UINavigationController，如下所示
let rootViewController = self.window?.rootViewController as! UINavigationController
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let mvc = storyboard.instantiateViewControllerWithIdentifier("MyViewController") as!
MyViewController
rootViewController.pushViewController(mvc, animated: true)
这对我来说很好，并且我没有丢失应用程序的正确导航属性。补充了前面答案的信息。 根据您的状态，您可以更改逻辑。 在方法中，破产管理通知：
func应用程序（应用程序：UIApplication，didReceiveMemotentification用户信息：[NSObject:AnyObject]）{}let state=UIApplication.sharedApplication（）.applicationState
开关状态{
案例UIApplicationState.Active：
案例UIApplicationState.Inactive：
案例UIApplicationState.背景：
}
根据应用程序的当前状态执行所需的操作。最佳答案是Swift Rabbit 我要补充的是，当应用程序从关闭状态变为活动状态时，它仍然缺失 您可以将以下选项添加到AppDelegate中的didFinishedLaunchingWithOptions中：
UIApplication.sharedApplication().registerUserNotificationSettings ( UIUserNotificationSettings(forTypes: (UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound), categories: nil))
if( launchOptions != nil){
var notificationDict: AnyObject? = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey]
if(notificationDict != nil){
handleNotification(notificationDict! as! [NSObject : AnyObject])
}
}
if let notification = launchOptions?[.remoteNotification] as? [AnyHashable : Any] {
notificationsUserInfo = notification as [AnyHashable : Any]
serveNotifications = true
}
