Am I right with my understanding, that an UIApplication object, UIWindow object, UIView object or any UIView subclass is an "Responder object"?
Here they say:
Responder objects in an application include instances of UIApplication, UIWindow, UIView, and...

Is there any data control available (in .NET) for a complex object (object with children objects). Something like a gridview but with hiperlinks which will take you to child object.

There is also a treeview control.
You can nest ListView (or gridview if that makes sense for the scenario) .

Example:
I have an class that inherits from UIImageView. An object creates an instance from that class. Now, that class needs a weak reference to it's parent. I could make an initializer where the object has to pass "self" to the new created object. But...

With such a function even if it was available is what would occur if the "parent" object has been.

Of the object (i.e., you're sure there are no references to it or can update them), you could do something like this with the Objective-C runtime functions :
newB = object_copy(a, class_getInstanceSize(B)); object_setClass....

Need to think about whether you want to have your Task object retain your controller object, but in the example you've given, you almost certainly don't want to, since your Controller object will be retaining your Task object....

In Objective C, is there a way to determine at runtime, if an object is retained, which other object might be retaining that object?
Or to phrase it a little differently:
If there are leashes on the dog is it possible to know who is holding the leash?...

Every time you retain, you add....
If you want to keep track of who is retaining an object, you need to do this yourself.
Such an object, since you can call retain from inside a plain vanilla C function, which has no associated object.

When you create an object as a member of another object:
$this->my_new_object = new a reference to the parent element to the object when you create it:
class innerclass(){ private $parent; // Reference to the parent ....

I have something similar to this:

That is definitely the expected ....
The object is being added to both lists originally by reference, and then subsequently you're assigned a reference in the list to the new object you're creating.
