I have a controller object with an ivar "myDict"
I have a nib with an NSArrayController bound to this object with a keypath
of myDict.@allValues
This works, but when I want to add an item to the dict (and have it
reflected in the arraycontroller), the method in my object is:
[self willChangeValueForKey:@"myDict"];
NSDictionary* test =
[NSDictionary dictionaryWithObjectsAndKeys:@"someValue", @"someKey", nil];
[myDict setValue:test forKey:@"someOtherKey"];
[self didChangeValueForKey:@"myDict"];
This works too, but how can I do this without the willChange/didChange ?
Shoudln't the setValue call, fire a KVO message?
Thanks,
Trygve
