In case my question wasn't clear...

@interface Foo : NSView

should [fooInstance isKindOfClass: [NSView class]] return NO after the
posing?

It appears to my sample code.

If the order of events is..

foo = [[NSView alloc] init];

[[MyImposter class] poseAsClass:[NSView class]];

then you will get NO for

[foo isKindOfClass:[NSView class]];


After the posing, [NSView class] returns what you think of as
MyImposter. So looking at Greg's diagram, is foo a kind of 'NSView'?
No.

So if that is the case, then it is ill-adviced to pose as NSView if you do so at some random point in the applications lifetime after other NSViews have been created, because then you won't be able to identify them by type at runtime? (And therefor Apple's private class has a bug and my workaround is the right thing to do?)

Thanks,
Jim
