我正在尝试将 VIPER 架构与 SwiftUI 一起使用,使用一些我已经在 UIKit 中使用的协议。
这些是我的BasePresenter
和Assembler
实现:
class BasePresenter <V, I, R>: NSObject, Presenter {
typealias View = V
typealias Interactor = I
typealias Router = R
var view: View!
var interactor: Interactor!
var router: Router!
func viewDidLoad() {
print("Base presenter: Viewdidload")
}
}
protocol Assembler {
associatedtype CustomView: ViewProtocol
associatedtype CustomInteractor: Interactor
associatedtype CustomPresenter: Presenter
associatedtype CustomRouter: Router
static func assembleView(_ view: CustomView) -> CustomView
}
extension Assembler {
static func assembleView(_ view: CustomView) -> CustomView {
let presenter = CustomPresenter.init()
var view = view
presenter.view = (view as! CustomPresenter.View)
view.presenter = (presenter as! CustomView.Presenter)
let interactor = CustomInteractor.init()
interactor.presenter = (presenter as! CustomInteractor.Presenter)
presenter.interactor = (interactor as! CustomPresenter.Interactor)
let router = CustomRouter.init()
router.presenter = (presenter as! CustomRouter.Presenter)
presenter.router = (router as! CustomPresenter.Router)
return view
}
}
在我想添加环境对象之前,它与 SwiftUI 视图一起工作得很好。
问题是,如果我以这种方式添加它:
LoginAssembler.assembleView(LoginView()).environmentObject(user)
当我尝试修改它时应用程序崩溃
作为该视图的祖先,可能缺少一个
View.environmentObject(_:)
forUserModel
我试图将环境对象注入更改为视图的初始化,但是它不再是类型LoginView
(它是ModifiedContent<...>
)并且汇编程序崩溃了。
let view = view.init().environmentObject(environmentObject)
let presenter = CustomPresenter.init()
print(view is LoginView) // Prints false
知道我可以用什么来组装我的模块并使 environmentObject 选项起作用吗?
