Question

我目前正在尝试使用Typhoon将依赖注入添加到我的应用程序中，这是现在的一半Swift，一半是传统的Objective-C。我试图从我的程序集中的Storyboard实例化一个视图控制器，但我正在下面的崩溃中运行。我在这里阅读https://github.com/appsquickly/Typhoon/issues/293使用NSString可以解决这个问题，但正如你在下面我所看到的那样，我已经做到了这一点并且不太有帮助...任何想法？

dynamic func typhoonStoryboard(name: NSString) -> AnyObject {
        return TyphoonDefinition.withClass(TyphoonStoryboard.self, configuration: { (definition) -> Void in
            definition.useInitializer("storyboardWithName:factory:bundle:", parameters: { (initializer) -> Void in
                initializer.injectParameterWith(name)
                initializer.injectParameterWith(self)
                initializer.injectParameterWith(NSBundle.mainBundle())
            })
        })
    }

 dynamic func viewController(withStoryboardName storyboardName: NSString, storyboardIdentifier: NSString) -> AnyObject {
        return TyphoonDefinition.withFactory(self.typhoonStoryboard(NSString(string: storyboardName)), selector: "instantiateViewControllerWithIdentifier:", parameters: { (method) -> Void in
            method.injectParameterWith(NSString(string: storyboardIdentifier))
        }, configuration: { (definition) -> Void in

        })
    }

知道可能出现什么问题吗？就像你看到我已经在使用NSString进行解决方法但它仍然因以下异常异常而崩溃...

Typhoon是一种相当典型的内省和反射型DI容器，针对Objective-C进行了优化。（对Swift也很有效）。

启动时：Typhoon从所有装配中收集有关如何构建对象的信息
在运行时：汇编界面摆在TyphoonComponentFactory前面，它知道如何根据所有这些收集的规则发出组件。

获取组件：

Rules parsed on startup->post processing->factory emits built objects

因此：在运行时参数的情况下，我们不能在它们上调用任何方法，或者在传入之后操纵它们，因为当Typhoon构建对象实例化蓝图时，这与启动阶段无关。

如果声明类型为NSString的运行时参数，并且直接传递它而不进行操作（而不是NSString(string: storyboardIdentifier)），它应该可以正常工作。

Typhoon + Swift：使用运行时参数时崩溃
