Is it possible to track changes to all properties of an NSObject?

Question

Objective-C

Only one way comes to mind: get a list of all properties through runtime and in a loop do addObserver for each field.
Are there other, less artisanal options?

I guess it depends on what you want to catch. Moreover, not all properties of KV-Observable.
If you want to track changes through setters, you can try to overload methodForSelector: or make method swizzling on it. There, to determine which selector is called, if it starts with "set", then the value is expected to change. We call our handler, we call the original method.
Tell us more about the problem, it will be easier to answer more specifically
