For one thing is it possible to print out the current retain
counter of an object?
Just for some debugging purpose?
- (unsigned)retainCount does this ! This is an instance method of
NSObject.
Be aware that you really shouldn't pay attention the results given by
retainCount, since there is often a great deal of behind the scenes
retaining going on, and so the values you see may not be at all what
you expect.
Simply using a variable as a parameter to another method can cause
that retain count to go up (and possibly cause other variables retain
counts to go down).
For example
foo1 = ... some object
foo2 = ... some other object
[x doSomething: foo1];
// at this point, foo1 may be +1, or maybe not
[x doSomethingElse: foo2];
// at this point, foo2 may be +1, and foo1 may even be -1, or
maybe not
As a result of these values changing in ways that are often non-
obvious, treat any conclusions drawn from the values of retainCount
(or the delta of those values) with a grain of salt.
