1. 文件列表

1.1 我的文件——MyFileViewController.swift

  • 数据获取——通过 SA 接口获取数据 
        NetworkManager.shared.fileList(path: "/", page: page, page_size: 30) {[weak self] response in
            guard let self = self else {return}
            LoadingView.hide()
            self.tableView.mj_header?.endRefreshing()
            self.tableView.mj_footer?.endRefreshing()
    
            // 删选没有可读权限的文件
            let datas = response.list.filter({$0.read != 0})
            
            if isReload {// 下拉刷新 or 首次加载数据
                if datas.count == 0 {
                    self.tableView.mj_footer?.isHidden = true
                    self.tableView.reloadData()}else{self.emptyView.removeFromSuperview()
                        self.currentDatas = datas
                        self.tableView.reloadData()}
            }else{// 上拉加载更多数据
                if !response.pager.has_more {// 已无数据
                    self.tableView.mj_footer?.endRefreshingWithNoMoreData()
                    self.isGetAllData = true
                    return
                }
                self.isGetAllData = false
                self.currentDatas += datas
                self.tableView.reloadData()}
        } failureCallback: {[weak self] code, err in
            guard let self = self else {return}
            LoadingView.hide()
            self.tableView.mj_header?.endRefreshing()
            self.tableView.mj_footer?.endRefreshing()
            
            if self.currentDatas.count == 0 {self.tableView.addSubview(self.emptyView)
                    self.emptyView.snp.makeConstraints {$0.center.equalToSuperview()
                        $0.width.equalTo(Screen.screenWidth)
                        $0.height.equalTo(ZTScaleValue(110))
                    }
                }else{self.emptyView.removeFromSuperview()
                }
            self.showToast("\(err)")
        }
  • 此页面无抉择性能
  • 点击文件夹进入本人目录 
            let vc = ChangeFolderPlaceController()
            let nav = UINavigationController(rootViewController: vc)
            nav.modalPresentationStyle = .fullScreen
            self.present(nav, animated: true, completion: nil)

1.2 共享文件——ShareFileViewController.swift

用户能够获取到其余用户共享进去的文件夹.

/// 申请列表数据
private func getDiskData(){let page = (currentDatas.count / 30) + 1
        
        NetworkManager.shared.shareFileList(page: page, page_size: 30) {[weak self] response in
            guard let self = self else {return}
            print("申请胜利")
            LoadingView.hide()
            self.tableView.mj_header?.endRefreshing()
            self.tableView.mj_footer?.endRefreshing()
            
            // 删选没有可读权限的文件
            let datas = response.list.filter({$0.read != 0})
            self.currentDatas.append(contentsOf: datas)
            
            
            if !response.pager.has_more {self.tableView.mj_footer?.endRefreshingWithNoMoreData()
            }

            if self.currentDatas.count == 0 {
                // 空数据展现页面
                self.tableView.addSubview(self.emptyView)
                self.emptyView.snp.makeConstraints {$0.center.equalToSuperview()
                    $0.width.equalTo(Screen.screenWidth)
                    $0.height.equalTo(ZTScaleValue(110))
                }
                self.tableView.reloadData()}else{self.emptyView.removeFromSuperview()
                self.tableView.reloadData()}

        } failureCallback: {[weak self] code, err in
            guard let self = self else {return}
            print("申请失败")
            LoadingView.hide()
            self.tableView.mj_header?.endRefreshing()

            if self.currentDatas.count == 0 {
                // 空数据展现页面
                self.tableView.addSubview(self.emptyView)
                    self.emptyView.snp.makeConstraints {$0.center.equalToSuperview()
                        $0.width.equalTo(Screen.screenWidth)
                        $0.height.equalTo(ZTScaleValue(110))
                    }
                }else{self.emptyView.removeFromSuperview()
                }
            self.showToast("\(err)")
        }
    }
  • 共享文件与我的文件页面逻辑大致相同，但其余用户共享过去的文件夹容许抉择功能模块 
       // MARK: - funtionTabbarAction
        funtionTabbarView.shareBtn.clickCallBack = { _ in
            print("点击分享到")
            let shareVC = FileShareController()
            shareVC.fileDatas = self.seletedFiles
            self.navigationController?.pushViewController(shareVC, animated: true)
            self.hideFunctionTabbarView()}
        funtionTabbarView.downloadBtn.clickCallBack = { _ in
            print("点击下载")
        }
        funtionTabbarView.copyBtn.clickCallBack = {[weak self] _ in
            guard let self = self else {return}
            print("点击复制到")
            let vc = ChangeFolderPlaceController()
            vc.isRootPath = true
            vc.currentPaths = ["根目录"]
            vc.seletedFiles = self.seletedFiles
            vc.type = .copy
            let nav = UINavigationController(rootViewController: vc)
            nav.modalPresentationStyle = .fullScreen
            self.present(nav, animated: true, completion: nil)

                if name.isEmpty {SceneDelegate.shared.window?.makeToast("请输出名称".localizedString)
                    return
                }
                if let originalExtension = file.name.components(separatedBy: ".").last,
                   let newExtension = name.components(separatedBy: ".").last
                {
                    if originalExtension != newExtension && file.type == 1 {let alertViewController = UIAlertController(title: "", message:" 更改文件类型可能导致文件不可用, 是否持续?", preferredStyle: .alert)
                        alertViewController.addAction(UIAlertAction(title: "勾销".localizedString, style: .cancel, handler: nil))
                        alertViewController.addAction(UIAlertAction(title: "确定".localizedString, style: .default, handler: { [weak self] _ in
                            guard let self = self else {return}
                            LoadingView.show()

                                self.setNameView?.removeFromSuperview()
                                self.hideAllFuntionView()
                                self.tableView.reloadData()
                                LoadingView.hide()
                                SceneDelegate.shared.window?.makeToast("重命名胜利".localizedString)
                            } failureCallback: { code, err in

                                LoadingView.hide()}
                        }))
                        self.present(alertViewController, animated: true, completion: nil)
                        return
                    }
                }

1.3 文件夹子集目录——FolderViewController.swift

  1. 子集目录可存在各类型文件的存在模式，依据数据 model 的 type 来辨别。

2. 子集目录点击文件类型是，展现 functionView，性能依据权限凋谢。
3. 子集目录文件及文件夹均可抉择，展现性能 tabbar。

2. 文件夹共享

用户能够将文件夹共享给选中的用户, 并依据本身需要赋予他们读写删的权限.

​

   /// 共享文件夹给用户
    private func shareFilesToCloud() {var filePaths = [String]()
        for file in fileDatas {filePaths.append(file.path)
        }
        
        if seletedUsers.count == 0 {return}
        let userIds = seletedUsers.map(\.user_id)
        let editMemberAlert = EditShareMemberAlert()
        editMemberAlert.set(members: seletedUsers)
        editMemberAlert.reSetBtn()
        // 权限判断
        if self.fileDatas.filter({$0.read == 0}).count > 0 {// 没有可读权限
            editMemberAlert.readBtn.isUserInteractionEnabled = false
            editMemberAlert.readBtn.alpha = 0.5
        } else {
            editMemberAlert.readBtn.isUserInteractionEnabled = true
            editMemberAlert.readBtn.alpha = 1
            editMemberAlert.readBtn.isSelected = true
        }
        if self.fileDatas.filter({$0.write == 0}).count > 0 {// 没有写入权限
            editMemberAlert.writeBtn.isUserInteractionEnabled = false
            editMemberAlert.writeBtn.alpha = 0.5
        } else {
            editMemberAlert.writeBtn.isUserInteractionEnabled = true
            editMemberAlert.writeBtn.alpha = 1
        }
        if self.fileDatas.filter({$0.deleted == 0}).count > 0 {// 没有删权限
            editMemberAlert.deleteBtn.isUserInteractionEnabled = false
            editMemberAlert.deleteBtn.alpha = 0.5
        } else {
            editMemberAlert.deleteBtn.isUserInteractionEnabled = true
            editMemberAlert.deleteBtn.alpha = 1
        }
        editMemberAlert.sureCallback = {[weak self] read, write, delete in
            guard let self = self else {return}
            LoadingView.show()
            NetworkManager.shared.shareFiles(paths: filePaths, usersId: userIds, read: read, write: write, delete: delete, fromUser: UserManager.shared.currentUser.nickname) { respond in
                SceneDelegate.shared.window?.makeToast("共享胜利".localizedString)
                editMemberAlert.removeFromSuperview()
                LoadingView.hide()
                self.navigationController?.popViewController(animated: true)
                
            } failureCallback: { code, err in
                LoadingView.hide()
                SceneDelegate.shared.window?.makeToast("共享失败".localizedString)
            }
        }
        SceneDelegate.shared.window?.addSubview(editMemberAlert) 
    }

3. 文件上传下载

3.1 文件上传选择器


 

文件上传选择器中图片和视频的选择器采纳的是第三方库 TZImagePickerController, 具体介绍及应用办法可参考 TZImagePickerController, 其余文件的选择器则采纳零碎自带的 UIDocumentPickerViewController.

3.2 文件上传下载性能

  

智汀云盘 App 的上传、下载性能是调用 gomobile 封装的库实现的. 该库实现了文件的分片上传、分片下载、断点续传等性能，能够很不便的给客户端调用.iOS 端基于该库封装了 GoFileManager 类，不便我的项目中应用.

GoFileManager 类代码片段:

  /// 下载工作
    /// - Parameters:
    ///   - url: 工作 url
    func download(path: String) {goOperationQueue.async { [weak self] in
            guard let self = self else {return}
            print(Thread.current)
            /// 家庭 scopeToken
            let scopeToken = AreaManager.shared.currentArea.scope_token
            
            /// 文件夹明码
            let pwd = self.getDirDownloadPwd(by: path)

            let downloader = GonetGetFileDownloader(self.downloadUrlFromPath(path), self.goCachePath, "{\"scope-token\":\"\(scopeToken)\", \"pwd\":\"\(pwd)\"}")
            self.taskCountChangePublisher.send(())
            
            if self.getDownloadingCount() < 2 {downloader?.start(self.goDownloadCallbackObj)
            }
            
        } 
    }
    /// 上传文件
    /// - Parameters:
    ///   - urlPath: 上传地址
    ///   - filename: 文件名
    ///   - tmpPath: 文件地位 (图片、视频为绝对路径  其余文件为沙盒 tmp 下相对路径)
    ///   - scopeToken: scopeToken
    func upload(urlPath: String, filename: String, tmpPath: String) {goOperationQueue.async { [weak self] in
            guard let self = self else {return}
            
            var filePath = tmpPath
            if let path = tmpPath.components(separatedBy: "file://").last {filePath = path}
            
            let scopeToken = AreaManager.shared.currentArea.scope_token
            let pwd = self.getDirUploadPwd(by: urlPath)

            let uploader = GonetGetFileUploader("\(urlPath)\(filename)", self.goCachePath, filePath, filename, "{\"scope-token\":\"\(scopeToken)\", \"pwd\":\"\(pwd)\"}")
            try? uploader?.createTmpFile()
            self.taskCountChangePublisher.send(())
            
            
            if self.getUploadingCount() < 2 {uploader?.start(self.goUploadCallbackObj)
            }  
        }
    }

4.4 权限阐明

  • 读：model 类型的 read 为 0 则无可读权限，为 1 则有可读权限。

    1、查看该文件夹及其上面所有文件 / 文件夹的权限；2、有权限才展现对应文件夹的入口

  • 写：model 类型的 write 为 0 则无可写权限，为 1 则有可写权限。

    1、包含新建文件夹、上传、重命名、共享、下载的权限；2、有权限才展现对应操作的入口；

  • 删：model 类型的 delete 为 0 则无可删权限，为 1 则有可删权限。

    1、包含挪动、删除的权限；

    2、有权限才展现对应的操作的入口；

    3、有挪动、复制的权限，不代表能胜利挪动复制，须要看是否有移入文件夹的【写】权限，有能力操作；
