如何在Viper架构的项目中创建良好的路由?我开始创建路由文件,但我不明白我接下来要做什么.
我创建了一个文件线框第一个控制器和线框协议:
// ChooseLanguageWireframeProtocol.swift
import UIKit
@objc protocol ChooseLanguageWireframeProtocol {
func presentChooseLanguageViewControllerWindow()
func presentAuthScreenViewController()
}
在文件线框我添加:
// ChooseLanguageWireframe.swift
import UIKit
class ChooseLanguageWireframe: NSObject , ChooseLanguageWireframeProtocol{
var chooseLanguageScreenViewController: ChooseLanguageViewController?
var window: UIWindow?
func presentChooseLanguageViewControllerWindow() {
let chooseLanguageViewController = UIStoryboard.init(name: "ChooseLanguage", bundle: nil).instantiateViewController(withIdentifier: "ChooseLanguage") as? ChooseLanguageViewController
self.chooseLanguageScreenViewController = chooseLanguageViewController
self.window!.rootViewController = chooseLanguageScreenViewController
self.window!.makeKeyAndVisible()
}
func presentAuthScreenViewController() {
}
}
在我创建RootWireframe之后
// RootWireframe.swift
import UIKit
class RootWireframe: NSObject {
let chooseLanguageScreenWireframe : ChooseLanguageWireframe?
override init() {
//What i must init??
}
func application(didFinishLaunchingWithOptions launchOptions: [AnyHashable: Any]?, window: UIWindow) -> Bool {
self.chooseLanguageScreenWireframe?.window = window
return true
}
}
在AppDelegate文件中我只更改
var window: UIWindow?
let rootWireframe = RootWireframe()
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
self.rootWireframe.application(didFinishLaunchingWithOptions: launchOptions as [NSObject : AnyObject]?, window: self.window!)
}
我必须添加或更改正确的工作?
最佳答案 2种可能性:
更改rootViewframe的init以接受您的依赖项并初始化它.
顺便说一下你的变量类型不应该是真正的类型而是协议,所以你可以在测试中轻松地模拟它
let chooseLanguageScreenWireframe : ChooseLanguageWireframeProtocol?
override init(chooseLanguage: ChooseLanguageWireframeProtocol) {
self.chooseLanguageScreenWireframe = chooseLanguage
}
然后在appdelegate中创建chooseLanguageWireframe实现并将其传递给构造函数.
这使得依赖性清晰可见.您也可以删除选项,因为您始终初始化它.
或解决方案2
在appdelegate中创建chooseLanguageWireframe并将其注入构造函数外部
lazy var rootWireframe = {
let r = RootWireframe()
r.chooseLanguageScreenWireframe = self.chooseLanguageScreenWireframe
return r
}
无论如何,您需要在某处实例化您的依赖项,它们无法自动创建.
您通常使用工厂并在依赖注入框架的帮助下执行此操作(检查SwiftInject或Typhoon)
此外,使用协议类型声明所有依赖项,VIPER体系结构的目的是简化测试和模拟与actor之间的隔离
