So, I added an observer to my awakeFromNIb:
[subscriptionsArrayController addObserver: self
forKeyPath: @"arrangedObjects"
options: NSKeyValueObservingOptionNew
context: NULL];
and the following method:
- (void) observeValueForKeyPath: (NSString *) keyPath
ofObject: (id) object
change: (NSDictionary *) change
context: (void *) context
{
NSLog(@"arrangedObjects changed");
}
and as expected i receive the log when I make changes via the UI (altough its
getting called multiple times, but I can optimise that later....) but not when
I try to add manually?
what would be my next plan of attack here?
