Does adding a KVO observer to self cause a memory leak?


In a nsobject you have a property "keyPath" you want to observe itself and you use

[self addObserver:self forKeyPath:keyPath options:NSKeyValueObservingOptionNew context:nil];

Does the above line cause a retain cycle?

I present this question because I wanted to know if it was a viable alternative to rewriting a bunch of setter functions.


Solution

  • From the docs:

    Neither the receiver, nor anObserver, are retained.
