ios - 台风 + swift : Crash when using run-time arguments

Question

我目前正在尝试使用 Typhoon 将依赖注入(inject)添加到我的应用程序中，该应用程序现在一半是 Swift，一半是遗留的 Objective-C。我正在尝试从我的程序集中的 Storyboard实例化 View Controller ，但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 可以解决问题，但正如您在下面看到的那样，我已经这样做了，但并没有太大帮助……有什么想法吗？

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

        })
    }

知道哪里出了问题吗？如您所见，我已经在使用 NSString 进行变通，但它仍然因以下异常异常而崩溃...

Answer 1

Typhoon 是一个相当典型的内省(introspection)和反射类型的 DI 容器，针对 Objective-C 进行了优化。 (也适用于 Swift)。

• 启动时:Typhoon 从所有程序集中收集有关如何构建对象的信息
• 在运行时:组装接口(interface)位于 TyphoonComponentFactory 前面，它知道如何根据所有这些收集到的规则发出组件。

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，我们不能对它们调用任何方法，或者在传入后以其他方式操作它们，因为这与 Typhoon 构建对象实例化蓝图时的启动阶段无关。

如果您声明 NSString 类型的运行时参数，并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。
