In the target argument I pass self, and as selector a method of the

address I passed when creating the timer. Inside the method I call
setNeedsDisplay: so the drawRect method is called in the event loop.
That call never happens and only when I force the redrawing of the
view through dragging or overlapping windows, the drawRect is called
but with a different address on self.
I don't understand what is happening. Are there two instances ?
You already answered your own question. If you see two different
values for 'self' for two objects of your view subclass then of course
there are two instances.
This situation usually comes about when a view is created in code, and
a view of the same class is also added to a NIB file.
Note that, because the view you're actually controlling via the timer
(presumably the one created in code) doesn't draw, it probably hasn't
been added to a superview either. It sounds like you accidentally
created a new view instead of getting a reference to the one in the
NIB file using an IBOutlet.
