In iOS 9.3 wordt de methode didReceiveRemoteNotificationin beide volgende gevallen aangeroepen.
1) Wanneer de pushmelding is ontvangen
2) Wanneer de gebruiker de app start door op de melding te tikken.
Maar op iOS 10 merk ik dat de didReceiveRemoteNotification-methode NIETwordt geactiveerd wanneer de gebruiker de app start door op de melding te tikken. Het wordt alleen aangeroepen wanneer de melding is ontvangen. Daarom kan ik geen verdere actie ondernemen nadat de app is gestart vanuit een melding.
Wat zou hier de oplossing voor moeten zijn? Enig idee?

voor voorbeeld zie dit
importeer het
UserNotifications-framework en voeg deUNUserNotificationCenterDelegatetoe in Appdelegate
import UserNotifications
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate,UNUserNotificationCenterDelegate
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
//create the notificationCenter
let center = UNUserNotificationCenter.current()
center.delegate = self
// set the type as sound or badge
center.requestAuthorization(options: [.sound,.alert,.badge, .providesAppNotificationSettings]) { (granted, error) in
// Enable or disable features based on authorization
}
application.registerForRemoteNotifications()
return true
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
// let chars = UnsafePointer<CChar>((deviceToken as NSData).bytes)
var token = ""
for i in 0..<deviceToken.count {
//token += String(format: "%02.2hhx", arguments: [chars[i]])
token = token + String(format: "%02.2hhx", arguments: [deviceToken[i]])
}
print("Registration succeeded!")
print("Token: ", token)
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
print("Registration failed!")

AppDelegate.h heeft deze regels:
Stap-1
//Add Framework in your project "UserNotifications"
#import <UserNotifications/UserNotifications.h>
@interface AppDelegate : UIResponder <UIApplicationDelegate,UNUserNotificationCenterDelegate>
Stap-2
AppDelegate.m
// define macro
#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
Stap-3
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
application.applicationIconBadgeNumber = 0;
if( SYSTEM_VERSION_LESS_THAN( @"10.0" ) ) {
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeprovidesAppNotificationSettings) categories:nil]];
[[UIApplication sharedApplication] registerForRemoteNotifications];
//if( option != nil )
//{
// NSLog( @"registerForPushWithOptions:" );
//}
} else {
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate = self;
[center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error) {
if( !error ) {
// required to get the app to do anything at all about push notifications
[[UIApplication sharedApplication] registerForRemoteNotifications];
NSLog( @"Push registration success." );
} else {
NSLog( @"Push registration FAILED" );
NSLog( @"ERROR: %@ - %@", error.localizedFailureReason, error.localizedDescription );
NSLog( @"SUGGESTIONS: %@ - %@", error.localizedRecoveryOptions, error.localizedRecoverySuggestion );
}
}];
}
return YES;
}
Dit wordt geactiveerd als gevolg van het aanroepen van registerForRemoteNotifications:
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
// custom stuff we do to register the device with our AWS middleman
}
Als een gebruiker op een melding tikt, wordt dit geactiveerd:
Dit wordt geactiveerd in iOS 10 wanneer de app op de voorgrond of op de achtergrond staat, maar niet is gesloten
-(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void
(^)(UIBackgroundFetchResult))completionHandler
{
// iOS 10 will handle notifications through other methods
if( SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO( @"10.0" ) )
{
NSLog( @"iOS version >= 10. Let NotificationCenter handle this one." );
// set a member variable to tell the new delegate that this is background
return;
}
NSLog( @"HANDLE PUSH, didReceiveRemoteNotification: %@", userInfo );
// custom code to handle notification content
if( [UIApplication sharedApplication].applicationState == UIApplicationStateInactive )
{
NSLog( @"INACTIVE" );
completionHandler( UIBackgroundFetchResultNewData );
}
else if( [UIApplication sharedApplication].applicationState == UIApplicationStateBackground )
{
NSLog( @"BACKGROUND" );
completionHandler( UIBackgroundFetchResultNewData );
}
else
{
NSLog( @"FOREGROUND" );
completionHandler( UIBackgroundFetchResultNewData );
}
}
of gebruik
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
[self application:application didReceiveRemoteNotification:userInfo fetchCompletionHandler:^(UIBackgroundFetchResult result) {
}];
}
Dan voor iOS 10, deze twee methoden:
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
willPresentNotification:(UNNotification *)notification
withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler
{
NSLog( @"Handle push from foreground" );
// custom code to handle push while app is in the foreground
NSLog(@"%@", notification.request.content.userInfo);
}
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
didReceiveNotificationResponse:(UNNotificationResponse *)response
withCompletionHandler:(void (^)())completionHandler
{
NSLog( @"Handle push from background or closed" );
// if you set a member variable in didReceiveRemoteNotification, you will know if this is from closed or background
NSLog(@"%@", response.notification.request.content.userInfo);
}
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
openSettingsForNotification:(UNNotification *)notification{
Open notification settings screen in app

Swift 4 en IOS 12.
Hoewel er meerdere redenen kunnen zijn (reeds genoemd in andere antwoorden) waarom dit probleem kon optreden, had in mijn persoonlijke geval de oplossing te maken met de lading bij het verzenden van de pushmelding:
U moet de sleutel “content-available”op de json-payload instellen op 1.
bijvoorbeeld:
{"aps":{"alert":"Test", "content-available":1, "badge":1,"sound":"default"}}

Ik had hetzelfde probleem. Er is een meldingsbanner verschenen, maar de methode -application:didReceiveRemoteNotification:fetchCompletionHandler:is niet aangeroepen. De oplossing die voor mij werkte, was om de implementatie van de methode - application:didReceiveRemoteNotification:toe te voegen en de oproep door te sturen naar -application:didReceiveRemoteNotification:fetchCompletionHandler::
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
[self application:application didReceiveRemoteNotification:userInfo fetchCompletionHandler:^(UIBackgroundFetchResult result){}];
}

Snelle code:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
if #available(iOS 10.0, *) {
let center = UNUserNotificationCenter.currentNotificationCenter()
center.delegate = self
}
// ...
return true
}
@available(iOS 10.0, *)
public func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
print(response.notification.request.content.userInfo)
}
@available(iOS 10.0, *)
public func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
print(notification.request.content.userInfo)

Het is een iOS-bug. Het zal worden opgelost in iOS 10.1. Maar wacht gewoon op 10.1-release in LGO in plaats van een nieuwe bibliotheek te implementeren en later te verwijderen.

BTW, dit probleem lijkt te worden opgelost in iOS 10.1. Ik heb mijn app getest op 10.1, alle werk prima

Ik denk dat dit zo is gedaan door design, ik werk momenteel aan iOS 14 en hetzelfde gebeurt. Wat ik me heb gerealiseerd, is dat als u ‘achtergrond opgehaald’ mogelijk maakt en implementeert de [DidreceIveremotenotification: WithcompletionHandler:] «Misschien wilt u dat ook met [Performbackgroundfetch:] ook», dan kunt u een breekpunt instellen in die delegatiemethode en Debug Remote Melding
