Summary:
A very common pattern I've seen in RN codebase:
- (instancetype) init {
[[NSNotificationCenter defaultCenter] addObserver:self ...]
}
- (void) dealloc {
[[NSNotificationCenter defaultCenter] removeObserver:self ...]
}
From Apple:
https://developer.apple.com/documentation/foundation/nsnotificationcenter/1413994-removeobserver?language=objc
> If your app targets iOS 9.0 and later or macOS 10.11 and later, you don't need to unregister an observer in its dealloc method.
RN targets iOS9+
Changelog: [Internal][Cleanup] Remove unneeded NSNotification center removeObserver
