Method	Description
AddObserverToKeyPathWithOptions ( this o, KNKVOObserver observer, String keyPath, KNKeyValueObservingOptions options, Object context ) : void	Adds an observer to a KVO-compliant key path of the receiver.
DidChangeValueForKey ( this o, String key ) : void	If a given property doesn't support auto-KVO, this MUST be called after changing a value for the property to be KVO-compliant.
RemoveObserverFromKeyPath ( this o, KNKVOObserver observer, String keyPath ) : void	Removes an observer from a KVO-compliant key path of the receiver.
WillChangeValueForKey ( this o, String key ) : void	If a given property doesn't support auto-KVO, this MUST be called before changing a value for the property to be KVO-compliant.

Adds an observer to a KVO-compliant key path of the receiver.

public static AddObserverToKeyPathWithOptions ( this o, KNKVOObserver observer, String keyPath, KNKeyValueObservingOptions options, Object context ) : void
o	this	The object to be observed.
observer	KNKVOObserver	The object to receive the change notifications.
keyPath	String	The key path to observe.
options	KNKeyValueObservingOptions	A bitwise-OR of the desired options. See the KNKeyValueObservingOptions enum for details.

o	this	The object to remove the observation from.
observer	KNKVOObserver	The observer to remove.
keyPath	String	The key path of the observation to remove.
return	void

If a given property doesn't support auto-KVO, this MUST be called before changing a value for the property to be KVO-compliant.
