PushNotificationIOS Documentation Has Step that Leads to Error

[mikeborozdin]

The documentation of PushNotificationIOS says one needs to add

   // Required to register for notifications
   - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
   {
    [RCTPushNotificationManager didRegisterUserNotificationSettings:notificationSettings];
   }
   // Required for the register event.
   - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
   {
    [RCTPushNotificationManager didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
   }
   // Required for the notification event.
   - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)notification
   {
    [RCTPushNotificationManager didReceiveRemoteNotification:notification];
   }

to AppDelegate.m

However, the first method, namely

   - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
   {
    [RCTPushNotificationManager didRegisterUserNotificationSettings:notificationSettings];
   }

results in an compilation error that says

No class method for selector 'didRegisterUserNotificationSettings:notificationSettings'

Hey mikeborozdin, thanks for reporting this issue!

React Native, as you've probably heard, is getting really popular and truth is we're getting a bit overwhelmed by the activity surrounding it. There are just too many issues for us to manage properly.

Are you using an older version of ReactNative? if you go to RCTPushNotificationManager.h file, you will be able to see the actual available methods for your version.

Same error here

Afaict, these methods all require application for the first argument, and the documentation, is just wrong? i.e.

// Required to register for notifications
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
  [RCTPushNotificationManager application:application didRegisterUserNotificationSettings:notificationSettings];
}
// Required for the register event.
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
  [RCTPushNotificationManager application:application didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
}
// Required for the notification event.
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)notification
{
  [RCTPushNotificationManager application:application didReceiveRemoteNotification:notification];
}

For the latest versions of react-native, see here:

react-native/Libraries/PushNotificationIOS/PushNotificationIOS.js

Lines 42 to 56 in 1dc5dca

	* // Required to register for notifications
	* - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
	* {
	* [RCTPushNotificationManager didRegisterUserNotificationSettings:notificationSettings];
	* }
	* // Required for the register event.
	* - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
	* {
	* [RCTPushNotificationManager didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
	* }
	* // Required for the notification event.
	* - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)notification
	* {
	* [RCTPushNotificationManager didReceiveRemoteNotification:notification];
	* }

I'm having the same error

react-native/Libraries/PushNotificationIOS/PushNotificationIOS.js

Lines 42 to 56 in 1dc5dca

	* // Required to register for notifications
	* - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
	* {
	* [RCTPushNotificationManager didRegisterUserNotificationSettings:notificationSettings];
	* }
	* // Required for the register event.
	* - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
	* {
	* [RCTPushNotificationManager didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
	* }
	* // Required for the notification event.
	* - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)notification
	* {
	* [RCTPushNotificationManager didReceiveRemoteNotification:notification];
	* }

This solves. the problem @rollick

but why isn't this mentioned in the Release note? it is a breaking change, no?

[yamill]

I have a fix for this. I'll be a submitting a PR sometime soon.

[scgough]

Can I confirm what solves the problem @rollick @jihopark ?

I have the following in my AppDelegate.m file but still have the No known class method for selector ### error on each of those methods.

#import "RCTPushNotificationManager.h"
...
// Required to register for notifications
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
  [RCTPushNotificationManager didRegisterUserNotificationSettings:notificationSettings];
}
// Required for the register event.
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
  [RCTPushNotificationManager didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
}

// Required for the notification event.
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)notification
{
  [RCTPushNotificationManager didReceiveRemoteNotification:notification];
}

UPDATE
Adding application:application (as @kushal suggested) to the beginning of each method seems to eradicate the issue:

// Required to register for notifications
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
  [RCTPushNotificationManager application:application didRegisterUserNotificationSettings:notificationSettings];
}
// Required for the register event.
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
  [RCTPushNotificationManager application:application didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
}

// Required for the notification event.
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)notification
{
  [RCTPushNotificationManager application:application didReceiveRemoteNotification:notification];
}
