Summary:
This is an updated version of #2336 and #7694.
---
This adds a `registrationError` event that is emitted by `PushNotificationIOS` whenever an application receives a registration error from APNS (APNS service failure, running on simulator, etc). This event fires to the exclusion of the `register` event (and vice versa).
**How to use**
Add the following to your `AppDelegate.m`:
```obj-c
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
[RCTPushNotificationManager didFailToRegisterForRemoteNotificationsWithError:error];
}
```
And register an event handler for the event:
```js
PushNotificationIOS.addEventListener('registrationError', function({ message, code }) {
// Complete your registration process in error.
});
```
**Test plan**
Added support for this event (and `register`) to UIExplorer as a proof of concept. Navigating to the push notifications example on a simulator is an easy way to reproduce this e
