As a C programmer I'm trying to avoid Objective C whenever and wherever
possible.
The good thing is that I can do most interaction with Cocoa from normal C
functions.
I only had to write very few classes. Most of the Cocoa stuff can be done
from normal C functions just fine.
Now I'd like to subscribe to the AVPlayerItemDidPlayToEndTimeNotification
notification. In an Objective C class, this is purportedly done like this:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(itemDidFinishPlaying:)
name:AVPlayerItemDidPlayToEndTimeNotification object:playerItem];
This will call the "itemDidFinishPlaying" method in class "self" whenever
an AVPlayerItem has finished playing.
Of course, I can't use this code in a normal C function because there are
references to "self" and the selector thing doesn't look like it's compatible to
C. So I could just subclass AVPlayerItem and voila, everything's fine.
Still, I'm wondering: Is it also possible to have NSNotificationCenter call
a C function for me whenever the notification triggers? Can this somehow
be achieved or am I forced to use full Objective C here?
