I have run into a real hard one here.

My class is self-created (a + (void) start;-method) which is sent a delegate.
I need to send the delegate a few messages through delegate-selectors. To check if the delegate was released, I have tried if (delegate == nil/NULL), but even if it really is released, it still says it wasn’t.

How do I go around to fix this? (delegate is assigned to an id)

This is how my app is built up:

AppDelegate
> NavController
>> TableView 
>>> Post 
>>>> GetData

GetData is the self-created class. Post is the delegate of GetData, and is released by TableView/NavController. After releasing Post, it is also set to nil.
In other words, GetData does not release it’s delegate!

    You can’t check if an object was released. Another object could’ve come along and occupied the same memory space, becoming indistinguishable with the original object.

    The user of a class with a delegate is responsible for setting the delegate to nil when the delegate object is released. It’s not detectable by the object itself.
