Question

I have a bunch of objects and I try and simulate events with them.

id completedSelectorTarget;
    SEL nextTripSelector;

Then I call perform selector on the selector target.

Well I created a double reference where the listener of the event completedSelectorTarget retains my object and completedSelectorTarget is retained by the object as well.

How do I avoid this? Is there a better way to do events? I thought to remove the retain on completedSelectorTarget, but then what will happen when I call perform selector? The whole thing will crash wont it? Is there a way to check if completedSelectorTarget has been released before I call perform selector? Or perhaps I’m just doing this wrong?

Answer 1

For now I’m using NSNotification Center. I notice that it crashes as well if you don’t remove the observer when it is released. Still it should save me time from writing my own code.
