I'm working with NSViewController to create a workflow of controllers.
I'm trying to patch the controller into the responder chain so that I
can implement action methods in the specific controllers and in the
window controller.
I'm using the following code in an attempt to create a responder chain
like this:
ButtonView -> ContainerView -> MyViewController -> WindowContentView -
> Window -> WindowController -> etc...
- (void)setViewController:(TLViewController *)controller {
if (_viewController != controller) {
[_viewController release];
_viewController = [controller retain];
_viewController.controller = self;
[self setActiveContentView:[_viewController view]];
// Patch into the responder chain
// This must be done after the view has a superview
[_viewController setNextResponder:[[_viewController view]
nextResponder]];
[[_viewController view] setNextResponder:_viewController];
}
}
However, it isn't working. The view controller doesn't receive any
messages so I've clearly overlooked something. I've confirmed in GDB
that all the -nextResponders are set correctly; I just can't figure it
out. I've also confirmed using -targetForAction:to:from: that the view
controller isn't returned as the target. Implementing the methods in
the window controller work and it's returned as the target as expected.
