How do you remove an observer from an object under ARC? Do we just add the observer and forget about removing it? If we no longer manage memory manually where do we resign from observing?
For example, on a view controller:
[self.view addObserver:self
forKeyPath:@"self.frame"
options:NSKeyValueObservingOptionNew
context:nil];
Previously, I would call removeObserver:
in the view controller's dealloc
method.
You still can implement -dealloc
under ARC, which appears to be the appropriate place to remove the observation of key values. You just don't call [super dealloc]
from within this method any more.
If you were overriding -release
before, you were doing things the wrong way.
