在应用程序委托之外注册远程通知
到目前为止，我所看到的一切都表明，我将在AppDelegate设置一个推送通知警报。 但是，我的应用程序要求用户完成注册过程，并且我不想询问用户是否希望接收推送通知，除非用户已经到达注册过程完成后出现的viewController 。
我能够把这些代码中的一些视图控制器的viewDidLoad方法，而不是我的应用程序委托？ 我是否需要在我的应用程序委托中保留这两个底部方法“ didRegisterForRemoteNotificationsWithDeviceToken ”和“ didRegisterForRemoteNotificationsWithDeviceToken ”，还是应该将它们移动到我尝试注册远程通知的位置？
我正在使用以下代码块在我的应用程序中注册推送通知：
在我的应用程序委托的didFinishLaunchingWithOptions方法中：
[application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge| UIRemoteNotificationTypeAlert| UIRemoteNotificationTypeSound];
在我的应用程序委托中添加的方法：
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { // Store the deviceToken } - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo { //handle push notification }
我所访问的资源表明这块代码
您可以随时进行注册电话 – 只有当您知道应用程序中您希望用户接收推送通知时，才会这样做。
两个应用程序委托callback必须在您的应用程序委托中，因为您在应用程序委托上注册通知types，并且只有一个。 我会build议做一个应用程序委托方法来调用，然后做注册，你可以通过[[UIApplication sharedApplication] delegate]从视图控制器调用它（将该调用的结果转换到您的应用程序委托类）。
这个答案是肯德尔·赫尔姆斯泰特·格尔纳（Kendall Helmstetter Gelner）的回答。肯德尔的答案有0票，但是对我来说非常好，而我没有足够的积分来回答问题。 按照肯德尔的build议，我的视图控制器，CMRootViewController.m – >
#pragma mark - push notificaiton -(void)registerToReceivePushNotification { // Register for push notifications UIApplication* application =[UIApplication sharedApplication]; [application registerForRemoteNotificationTypes: UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound]; }
和两个应用程序委托callback是在我的应用程序委托，CMAppDelegate.m – >
// handle user accepted push notification, update parse - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)newDeviceToken { // Store the deviceToken in the current installation and save it to Parse. PFInstallation *currentInstallation = [PFInstallation currentInstallation]; [currentInstallation setDeviceTokenFromData:newDeviceToken]; // enable future push to deviceId NSUUID *identifierForVendor = [[UIDevice currentDevice] identifierForVendor]; NSString* deviceId = [identifierForVendor UUIDString]; [currentInstallation setObject:deviceId forKey:@"deviceId"]; [currentInstallation saveInBackground]; } // handle push notification arrives when app is open - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo { [PFPush handlePush:userInfo]; }
谢谢肯德尔。
最好的方法是在您的应用程序委托方法中处理删除通知，使用NSNotificationCenter发出通知
[[NSNotificationCenter defaultCenter] postNotification:@"remoteNotification" withObject:whateverYouWantHere];
然后使用NSNotificationCenter添加任何感兴趣的UIViewControllers作为remoteNotification通知的观察者。

从AppDelegate之外调用推送通知
import UserNotifications class HomeViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let application = UIApplication.shared registerPushNotification(application) } func registerPushNotification(_ application: UIApplication){ UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]){ (granted, error) in if granted { print("Notification: Granted") } else { print("Notification: not granted") } } application.registerForRemoteNotifications() } } extension HomeViewController{ // Called when APNs has assigned the device a unique token func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { // Convert token to string let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)}) // Print it to console print("APNs device token: \(deviceTokenString)") // Persist it in your backend in case it's new } // Called when APNs failed to register the device for push notifications func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) { // Print the error to console (you should alert the user that registration failed) print("APNs registration failed: \(error)") } // Push notification received func application(_ application: UIApplication, didReceiveRemoteNotification data: [AnyHashable : Any]) { // Print notification payload data print("Push notification received: \(data)") } }

您发布的解决scheme是否有效？ 我曾试图做类扩展我想调用以下函数来检索设备令牌。 但是不叫。
唯一的方法是在AppDelegate中有这些function，我想避免。
// Called when APNs has assigned the device a unique token func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { // Convert token to string let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)}) // Print it to console print("APNs device token: \(deviceTokenString)") // Persist it in your backend in case it's new } // Called when APNs failed to register the device for push notifications func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) { // Print the error to console (you should alert the user that registration failed) print("APNs registration failed: \(error)") } // Push notification received func application(_ application: UIApplication, didReceiveRemoteNotification data: [AnyHashable : Any]) { // Print notification payload data print("Push notification received: \(data)") }
