I'm currently working on notification centers.
I read that there are 4 types of Notification Centers are there.
- NSNotificationCenter
- NSDistributedNotificationCenter
- DarwinNotificationCenter
- TelephonyNotificationCenter
In which NSNotificationCenter
I'm familiar with. TelephonyNotificationCenter
is private and not provided for developers.
My question is about NSDistributedNotificationCenter
and DarwinNotificationCenter
.
What is the use of these two notification centers ? Is it available for developers ? If available how can I use them ?
What I tried:
- Googled, got two reference (DarwinNotificationConcepts , NSDistributedNotificationCenter). But confused after reading.
- Read the iOS books available on this link, get a overview. But nothing in details
Thanks in advance
