ios - 如何在 iOS 应用程序中显示 Web 服务调用的进度条

问题描述

我想在 ios 应用程序中显示一个 Web API 调用的进度条。而不是在 Web 服务完成之前只向用户显示活动指示器，而是向他显示进度状态是用户友好的。我见过很多例子显示带有用户定义时间的进度条，但与 WEB api 调用持续时间无关。那么任何人都可以指导我完成上述任务吗？

解决方案

    // like iam using SVProgress for uplaod an image
// for showing Progress iam getting Progress.fractionCompleted from uploadProgress
eg:-

     Alamofire.upload(multipartFormData: { (multipartFormData) in
            multipartFormData.append(data!, withName: "media", fileName: "media.jpeg", mimeType: "media/jpeg")
            for (key, value) in parameters! {
              multipartFormData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
            }
          }, to:baseUrl,headers:parameters)
          { (result) in
            switch result {
            case .success(let upload, _, _):

              upload.uploadProgress(closure: { (Progress) in
                print("Upload Progress: \(Progress.fractionCompleted)")
                SVProgressHUD.showProgress(Float(Progress.fractionCompleted))
              })

              upload.responseJSON { response in
                //self.delegate?.showSuccessAlert()
                print(response.request)  // original URL request
                print(response.response) // URL response
                print(response.data)     // server data
                print(response.result)   // result of response serialization
                //                        self.showSuccesAlert()
                //self.removeImage("frame", fileExtension: "txt")
            SVProgressHUD.dismiss()

// Hope its works for you..
