Factory initialization with additonal property injection

问题

In my demo project I replaced the manual creation of a view controller with the factory-based creation within an assembly like so (as Jasper Blues demonstrated here: https://stackoverflow.com/a/24227246/397898)

// ApplicationAssembly

dynamic func mainStoryboard() -> AnyObject {
    return TyphoonDefinition.withClass(TyphoonStoryboard.self) {
        (definition) in

        definition.useInitializer("storyboardWithName:factory:bundle:") {
            (initializer) in

            initializer.injectParameterWith("Main")
            initializer.injectParameterWith(self)
            initializer.injectParameterWith(NSBundle.mainBundle())
        }

        definition.scope = TyphoonScope.Singleton
    }
}

// PersonListAssembly

dynamic func personListViewController() -> AnyObject {

        return TyphoonDefinition.withFactory(self.applicationAssembly.mainStoryboard(), selector: "instantiateViewControllerWithIdentifier:", parameters: {
            (factoryMethod) in

            factoryMethod.injectParameterWith("PersonListViewController")
        })
    }

But the view controller still needs some other dependencies. How can I inject the propery when doing this?

And actually I have two questions: All IBOutlets are nil, when I try to use the view controller like this. Am I missing something?

Correct answer based on Jasper's response

dynamic func personListViewController() -> AnyObject {

    return TyphoonDefinition.withClass(PersonListViewController.self) {
        (definition) in

        definition.factory = self.applicationAssembly.mainStoryboard()
        definition.useInitializer("instantiateViewControllerWithIdentifier:", parameters: { (factoryMethod) in

            factoryMethod.injectParameterWith("PersonListViewController")
        })

        definition.injectProperty("presenter", with: self.personListPresenter())
    }
}

It seems the shortcut way of declaring a component that is emitted from another Typhoon component does not support this (yet). We'll open an issue. Meanwhile you can fall back to Typhoon 1.0 style API:

- (id)currentTheme
{
    return [TyphoonDefinition withClass:[PFTheme class] 
        configuration:^(TyphoonDefinition* definition)
    {
        definition.factory = [self themeFactory];
        [definition useInitializer:@selector(sequentialTheme)];
    }];
}

. . when you use this approach:

An initializer (with or without args) is actually an instance method on the object that will produce the component.
Additional properties, scope, etc can be set.

We created the short way as its a little confusing to refer to an 'initializer' that is in fact an instance method on the class creating the component. It looks like there was an oversight in adding a configuration block.
