How to disable default notification alert view on iOS remote notifications? - ios

Question

In my app I enabled remote notifications,
if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(#"10.0")){
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate = self;
[center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error){
if( !error ){
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
}];
}else{
UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound);
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes categories:nil];
[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];
}
And I implemented the delegate methods as follows,
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error{
NSLog(#"Failed!!");
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
// Print message.
if (userInfo) {
NSLog(#"Message ID: %#", userInfo);
}
completionHandler(UIBackgroundFetchResultNoData);
}
But when the app is in foreground and receiving a notification, I got a UIAlertView with the notification title and message. I want to
//Called when a notification is delivered to a foreground app.
-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
NSLog(#"User Info : %#",notification.request.content.userInfo);
completionHandler(UNAuthorizationOptionSound | UNAuthorizationOptionBadge);
}
//Called to let your app know which action was selected by the user for a given notification.
-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler{
NSLog(#"User Info : %#",response.notification.request.content.userInfo);
completionHandler();
}
I debugged on willPresentNotification: and after this triggers I got the alert. And I tested by removing this method as well. But still this alert is showing when receiving a notification.
How may I disable this alert view? I'm using 10.2 iOS in my iPhone

Answer 1

I don't think the UIAlertController comes from notifications. Are you sure you are not creating one elsewhere ?
Your notifications' implementation seems ok.
Can you search in your project and using breakpoints to see if any of your UIAlertControllers get hit?

Answer 2

Use UNNotificationPresentationOptionNone in the completionHandler
-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
NSLog(#"User Info : %#",notification.request.content.userInfo);
completionHandler(UNNotificationPresentationOptionNone);
}
