(For simplicity, I implement an "int state" ivar to which drawRect

In init, this:
- (id)initWithFrame:(NSRect)frame {
self = ........
[self setCurrentColor:[NSColor yellowColor]];
[self setState: 1];
.........
}
Here is the relevant code in drawRect;
static int status = 0;
if (status == 0)
[ [self currentColor] set];
else if ( status % 2)
[[NSColor blackColor]set];
else
[[NSColor blueColor]set];
status +=1;
But this drawRect code doesn't use a "state" ivar, it uses a static
variable "status", so setState: won't ever affect drawRect.
1) Even though, as Quincey alluded to, I would have expected the
outlet "view" and self to be equivalent, they are not. It seems as
if "self" to changeViewDelta is a different entity from the outlet
"view".
Ah, that's a different kettle of fish. It sounds like you've created 2
view instances by mistake. Because you've got an 'initWithFrame', the
implication is that you are creating the view in code ('[[MyView
alloc] initWithFrame: frame]' somewhere). Because you've got a "view"
outlet, the implication is that you have a custom view object in a XIB
file.
Those are two different view objects. If that's what you've got, you
need to choose one technique or the other.
