While using ARC, life is much easier in terms of memory management; but, let's say I wish to look at a certain object while the app is running and see how many pointers are pointing to it at each certain point in the code. Is there a way to do that?
You can access the retain count using -retainCount or CFGetRetainCount but it will almost never give you any meaningful or useful information. Objects can be added to autorelease pools, retained by the various internals of the objective-c runtime or Apple frameworks, ARC, etc. You shouldn't really care how many people have retained an object, only whether you need a strong reference to it at any point in time.
