strange grammar, want ask if there cases if don't kvo (key value observation), app can't things/features? thanks key value observing offers functionality , behaviors unique , useful developer, in same cases offering glimpse @ values otherwise opaque. for example, if want know precise duration of animation in cocoa otherwise black-box (for example, keyboard disclosure animation duration), kvo way know of establish that. beyond that, it's useful pattern programming applications involve data (go figure). such, yet tool in developer's toolkit. can without it? sure. there many tools can without, , 1 takes little bit of effort wrap head around initially. should make point of avoiding it? no, don't think - why you?
