我在我的项目中使用moya进行api调用。
我有一个BaseViewController。在此 Controller 中,我编写了一些用于每个ViewController的通用方法。
BaseViewController有一个称为BaseViewModel的 View 模型。
所有 View 模型都派生自BaseViewModel。
我想在所有API完成后调用带有statusCode参数的函数。
然后在baseviewcontroller中,我想获取传递给函数的statuscode。
我宣布功能为属性(property),但我不知道如何使用它。
这是代码。
class BaseViewModel {
var onApiFetchCompleted: (Int)?
var isLoading = false {
didSet{
self.uploadLoadingStatus?()
}
}
var uploadLoadingStatus : (() -> (Void))?
}
class DataViewModel: BaseViewModel {
func get(_ params: [String], completion: @escaping (Response) -> ()){
var response = Response()!
ApiProvider.request(.request(params: params)) { result in
switch result {
case let .success(moyaResponse):
if moyaResponse.statusCode == 200 {
let json = try! moyaResponse.mapJSON() as! [String:Any]
response = Mapper<Response>().map(JSON: json)!
}
response.statusCode = moyaResponse.statusCode
super.onApiFetchCompleted(response.statusCode)
case let .failure(error):
print("")
}
completion(response)
}
}
}
class BaseVC: UIViewController {
lazy private var viewModel: BaseViewModel = {
return BaseViewModel()
}()
typealias onConfirmAccepted = () -> Void
typealias onConfirmDismissed = () -> Void
override func viewDidLoad() {
super.viewDidLoad()
viewModel.onApiFetchCompleted = {
//here i want to use passed statusCode parameter to function
if statusCode != 200 {
if statusCode == 403 {
returnToLogin(title: "Information", message: "Session Expired!")
}
else if statusCode == 401 {
self.showError(title: "Unauthorized Access", message: "You have not permission to access this data!")
}
else {
self.showError(title: "Error", message: "Unexpected Error. Call your system admin.")
}
}
}
}
}
最佳答案
我找到了解决方案:
在BaseViewModel中,我声明了一个函数:
var onApiFetchCompleted: ((_ statusCode: Int) -> ())?
并在baseViewController中:
func onApiFetchCompleted(statusCode: Int) {
//do what you want with status code
}
override func viewDidLoad() {
super.viewDidLoad()
viewModel.onApiFetchCompleted = { (statusCode:Int) -> () in
self.onApiFetchCompleted(statusCode: statusCode)
}
}
