I am an iOS programmer. I just started learning coding for MAC OSX . But now I am having tough time coding for MAC OSX . The terms KVO and Bindings making my life tougher. There are document available but none of the document gives complete idea to me .

My question is can I use KVO as an alternative to custom delegates . If so how to achieve this?

For eg, say I have a Class A and Class B, where A is the initial class . Now suppose my control moves from Class A to Class B , and if I want to achieve something from back in class A I can do the same very easily using custom delegate to pass the control to class A.

How to achieve this using KVO ? Any help is appreciated.

The Apple docs do a pretty good of covering this subject I thought. – trojanfoe Aug 23 '13 at 07:04

You can use KVO in iOS, it's not restricted to OS X. – Abizern Aug 23 '13 at 07:23
What do you mean by "my control moves from class A to class B"? – Khanh Nguyen Aug 23 '13 at 07:37
