Hi List!
here is the setup: I want to have a tableview with a String and a
Checkbox. All this is handled by a NSArrayController. Now I want to
know when the Checkboxes are clicked on and take an apropriate action.
For this action I need to know the string in the same row.
How do I do this?
My first thought was KeyValueObserving on the Model, so to say the
NSNumber that represents the bool with something like this:
[self addObserver:self forKeyPath:@"myArray.myBool"
options:(NSKeyValueObservingOptionNew |
NSKeyValueObservingOptionOld)
context:nil];
But a KeyPath like this is not allowed. Is there any Keypath for a
tomany relationship that works in this context? The "Array Operators"
don't work here. Observing only the array does not help either, because
then I do not get informed, when mutable content is changing. Basically
it's: How do I observe the contents of an Array?
Thanks,
dom
