I've just realized that drawRec is not even being called after I change the variables and call
[self setNeedsDisplay:YES]
Any ideas as to why the drawRec is not being called?

Greetings!
In my custom view I have a few straight lines, who's start and end points being set as instance variables within the view's class.
When the user causes the values for these variables to change I need to update the view.
All of my drawing routines are in the drawRec.
I have a separate method within this custom view class that changes the values for the variables.
After changing the values I call [self setNeedsDisplay:YES]
In my run log I can see that all the relevant methods get triggered as they should.
However, the view does not redraw.
What could be wrong?
