The local notification is not visible

[googlecomvn]

I have follow the instruction to install the lib in Xcode 9. I use local notification for my app and run in simulator iPhone 6 and run in real device iPhone 7 but the notification is not visible. Please help me My snippet code to show notification

_let localNotification = NotificationsIOS.localNotification({ alertBody: "Local notificiation!", alertTitle: "Local Notification Title",

    silent: false,
    category: "SOME_CATEGORY",
    userInfo: { }
});_

Same here, local notification not showing. I am testing in an iPhone X, iOS 11. The event notificationReceivedForeground does fire though.

Can confirm this as well. Thought it was my own fault at first causing a race condition since I remove old notifications before pushing a new one.

I really don't know how to show local notification, document is so difficult to understand and follow

[axlalvaro]

I managed to make localNotifications show up, by using UNUserNotificationCenter. Here is what I added:

AppDelegate.h

#import <UIKit/UIKit.h>
#import <UserNotifications/UserNotifications.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate, UNUserNotificationCenterDelegate>

@property (nonatomic, strong) UIWindow *window;

@end

AppDelegate.m

Just below the #imports:

#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)

In didFinishLaunchingWithOptions:

if( SYSTEM_VERSION_LESS_THAN( @"10.0" ) )
{
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    center.delegate = self;
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error)
    {
          if (!error)
          {
              [[UIApplication sharedApplication] registerForRemoteNotifications];  // required to get the app to do anything at all about push notifications
              NSLog( @"Push registration success." );
          }
          else
          {
              NSLog( @"Push registration FAILED" );
              NSLog( @"ERROR: %@ - %@", error.localizedFailureReason, error.localizedDescription );
              NSLog( @"SUGGESTIONS: %@ - %@", error.localizedRecoveryOptions, error.localizedRecoverySuggestion );
          }
    }];
}

Added methods:

- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
{
    [RNNotifications didReceiveRemoteNotification: formatUNNotification(notification)];

    completionHandler(UNNotificationPresentationOptionAlert);
}

// When notification is clicked
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler
{
    UNNotification *notification = response.notification;
    [RNNotifications didNotificationOpen: formatUNNotification(notification)];

    completionHandler();
}

static NSDictionary *formatUNNotification(UNNotification *notification)
{
  NSMutableDictionary *formattedNotification = [NSMutableDictionary dictionary];
  UNNotificationContent *content = notification.request.content;

  formattedNotification[@"identifier"] = notification.request.identifier;

  if (notification.date) {
    NSDateFormatter *formatter = [NSDateFormatter new];
    [formatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSSZZZZZ"];
    NSString *dateString = [formatter stringFromDate:notification.date];
    formattedNotification[@"fireDate"] = dateString;
  }

  formattedNotification[@"alertTitle"] =  RCTNullIfNil(content.title);
  formattedNotification[@"alertBody"] = RCTNullIfNil(content.body);
  formattedNotification[@"category"] = RCTNullIfNil(content.categoryIdentifier);
  formattedNotification[@"thread-id"] = RCTNullIfNil(content.threadIdentifier);
  formattedNotification[@"userInfo"] = RCTNullIfNil(RCTJSONClean(content.userInfo));

  return formattedNotification;
}

RNNotifications.h

In Project > Libraries > RNNotifications.xcodeproj > RNNotifications.h, add:

+ (void)didNotificationOpen:(NSDictionary *)notification;

Hi Axlalvaro Does your tips allow to show notification on the mode foreground?

[axlalvaro]

@googlecomvn yes!

[googlecomvn]

Hi Axlalvaro Thanks, I will try

[googlecomvn]

Hi Axlalvaro Has error with this following line in AppDelegate.m

[RNNotifications didReceiveLocalNotification:localNotification];

In Xcode 9.2 has error: Unknown receiver 'RNNotification'; did you mean 'UNNotification'?

[axlalvaro]

@googlecomvn Did you put the required methods in your AppDelegate.m?, as indicated here:

https://github.com/wix/react-native-notifications/blob/master/docs/installation.md

You have to add the methods specified in the link in the iOS section and import: #import "RNNotifications.h"

I just copied a piece of my AppDelegate.m, not the whole.

[googlecomvn]

Hi axlalvaro The Notification is now working. But when the app is suspended or closed, the notification is not working. Do you have any suggestion to this scenario

[googlecomvn]

I followed the instruction in link https://facebook.github.io/react-native/docs/linking-libraries-ios.html but in AppDelegate.m there is an error: RNNotifications.h' file not found, although I have the following import in this file

import "RNNotifications.h"

[Rob117]

It would be really awesome to get an update on this, because it seems like the latest build is broken. Is there a way to merge the code @axlalvaro wrote into the project?

[googlecomvn]

After searching around I have a simple solution at last (I tested on my iphone 7) : add this following method into AppDelegate.m

• (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 completionHandler(UNNotificationPresentationOptionAlert); }

@axlalvaro Your solution isn't 100% working though, they do show but when I click on push notification it doesn't trigger onNotificationOpened.

[axlalvaro]

@ItsNoHax You are right! I had more code in my project. I just edited my code above. Let me know if it works (it does for me)!

[ItsNoHax]

Will let you know tomorrow morning! Very much appreciated!

@axlalvaro I'm getting 'No known class method for selector 'didNotificationOpen:'

It's because the didNotificationOpen is not registered in the RNNotifications interface.

How did you work around it?

[axlalvaro]

@ItsNoHax Umm, I can't remember what I did, it was a long time ago, but reading the RNNNotifications.m, it does have the didNotificationOpen method. So I guess I just added it to the RNNotifications.h file. I updated my comment above with this line. Hope it finally works!

[ItsNoHax]

@axlalvaro But that means every time you clean/reinstall your node_modules that change will disappear? :/

[axlalvaro]

@ItsNoHax Yes, sad moment. I just can't think of any other way of achieving this in a fast way (no PRs), because the method didNotificationOpen is not exposed in the .h :(

[ItsNoHax]

@axlalvaro So with your changes the push notifications are showing but when I press them they are not triggering in the notificationOpened listeners :/

[axlalvaro]

@ItsNoHax Does it stop at didReceiveNotificationResponse in AppDelegate.m if you set a breakpoint?

[ItsNoHax]

So I managed to make it work partly through your solution, I used https://github.com/ds300/patch-package to make the function available in the header file (without having to make a fork or keep changes locally).

Also for the following method didReceiveNotificationResponse I had to make sure I pass the userInfo object of the formatted message to didNotificationOpen. If you pass the whole formatted message the listener get's a wrongly formatted notification.

I have the same issue. Local notifications doesn't work for me...

I tried this one but notification not received in the foreground. Do I need to install PushNotificationIOS to work? Background notifications are fine. Running in IOS 13.3
