Usage

JFObservableArray is a KVO-compliant array wrapper that informs observers of changes to the array's underlying structure. Clients can set up KVO as follows:

JFObservableArray *array = [JFObservableArray new];
[array addObserver:self forKeyPath:@"self" options:NSKeyValueObservingOptionNew context:nil];

And the changes can be observed as follows:

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context
{
    switch ([change[NSKeyValueChangeKindKey] integerValue]) {
        case NSKeyValueChangeInsertion: {
            // data was inserted at the indexes in change[NSKeyValueChangeIndexesKey]
            break;
        }
        case NSKeyValueChangeRemoval: {
            // data was removed at the indexes in change[NSKeyValueChangeIndexesKey]
            break;
        }
        case NSKeyValueChangeReplacement: {
            // data was replaced at the indexes in change[NSKeyValueChangeIndexesKey]
            break;
        }
        default:
            break;
        }
}
