Question

我在我的iOS项目中使用Moya Networking。我制作了一个具有以下方法的类：

class UserAdapter{

    static func getUsers(amount:Int=2, gender:Gender = .Male, success successCallback: @escaping ([UserModelMain]) -> Void, error errorCallback: @escaping (Swift.Error) -> Void, failure failureCallback: @escaping (MoyaError) -> Void) {

        let endpointClosure = { (target: UserTarget) -> Endpoint<UserTarget> in
            let defaultEndpoint = MoyaProvider.defaultEndpointMapping(for: target)
            return defaultEndpoint.adding(newHTTPHeaderFields: ["": ""])
        }

        let provider = MoyaProvider<UserTarget>(endpointClosure: endpointClosure, plugins: [NetworkLoggerPlugin(verbose: true), NetworkActivityPlugin(networkActivityClosure: { (activity, target) in
            switch activity
            {
            case .began:
                print("Network Activity began")
                UIApplication.shared.isNetworkActivityIndicatorVisible = true
            case .ended:
                print("Network Activity ended")
                UIApplication.shared.isNetworkActivityIndicatorVisible = false
            }
        })])

        provider.request(.getUsers(amount: amount, gender: gender)) { (result) in
            switch result {
            case .success(let response):
                 //TODO

            }
        }
    } }

我正在从我的视图控制器中调用它：

UserAdapter.getUsers(amount: 8, gender: .Female, success: { (response) in

    }, error: { (error) in
        // show error from server
    }, failure: { (error) in
        // show Moya error
    })

我需要使用NVActivityIndicatorView之类的任何自定义加载库来代替UIApplication.shared.isNetworkActivityIndicatorVisible。该怎么做？

    static func getUsers(amount:Int=2, 
gender:Gender = .Male, 
success successCallback: @escaping ([UserModelMain]) -> Void, 
error errorCallback: @escaping (Swift.Error) -> Void, 
failure failureCallback: @escaping (Moya.MoyaError) -> Void, 
progress progressCallback: ProgressBlock?, 
activity networkActivityCallback: @escaping (_ change: NetworkActivityChangeType) -> Void) {

            let userProvider = MoyaProvider<UserTarget>(endpointClosure: { (target: UserTarget) -> Endpoint<UserTarget> in
                let defaultEndpoint = MoyaProvider.defaultEndpointMapping(for: target)
                return defaultEndpoint.adding(newHTTPHeaderFields: ["": ""])
            }, plugins: [NetworkLoggerPlugin(verbose: true), NetworkActivityPlugin(networkActivityClosure: { (activity, target) in
                UIApplication.shared.isNetworkActivityIndicatorVisible = (activity == .began)
                networkActivityCallback(activity)
                switch activity
                {
                case .began:
                    print("Network Activity began")
                case .ended:
                    print("Network Activity ended")
                }
            })])
    //Other statements

    }

尝试一下...

print("Network Activity began")
Helper.showHUD()
UserAdapter.getUsers(amount: 8, gender: .Female, success: { (response) in
    print("Network Activity ended")
    Helper.hideHUD()
}, error: { (error) in
    // show error from server
    print("Network Activity ended")
    Helper.hideHUD()
}, failure: { (error) in
    // show Moya error
    print("Network Activity ended")
    Helper.hideHUD()
})

我已经遇到了这个问题，这是解决方案。

网络管理器

class HomeNetworkManager: HomeNetworkable
{
   // MARK: Properties

   private let provider: MoyaProvider<HomeAPI>

   // MARK: Initiallization

   init(provider: MoyaProvider<HomeAPI>)
   {
      self.provider = provider
   }

   convenience init()
   {
      let networkActivityClosure: NetworkActivityPlugin.NetworkActivityClosure = { (activity, _) in
      switch activity
      {
          case .began:
              Activity.startAnimating()
          case .ended:
              Activity.stopAnimating()
          }
      }
        
      var plugins : [PluginType] = []

      let networkActivityPlugin = NetworkActivityPlugin(networkActivityClosure: networkActivityClosure)
      plugins.append(networkActivityPlugin)
    
      let networkLogger = NetworkLoggerPlugin(verbose: true)
      plugins.append(networkLogger)
    
      let provider = MoyaProvider<HomeAPI>(plugins: plugins)
      self.init(provider: provider)
   }

   // MARK: Methods - Methods defined in HomeNetworkable Protocol
}

然后轻松使用它并免费获得活动指示器：

let homeNetworkManager = HomeNetworkManager()

注意： Activity是带有静态方法的类，显示了我的自定义活动指示器。

祝你好运！

在Moya中使用任何活动指标库
