Question

在我的应用程序内部，我希望用户能够登录DropBox，并浏览和查看他或她的文件和文件夹。这对我来说似乎是一项非常普遍的任务，所以我想知道是否有任何教程或示例代码？我无法在Google上找到任何内容。

我相信我可以自己使用表格视图和来自dropbox.com的Core API tutorial，但如果代码已经在那里，我不想浪费所有时间。

Answer 1

如果你在Objective c上查看它，你可以从这个链接获得一个演示项目。您可以在其中浏览rootdirectory的文件夹，也可以下载文件。

我遇到了同样的问题。我花了很长时间才找到答案，真的是压倒性的，因为它没有太多的信息。我这样做了：我很抱歉我的英语，不是我的第一语言。

安装Dropbox选择器https://www.dropbox.com/developers/chooser#ios 安装SwiftyDropbox

SwiftyDropbox安装Alamofire，我们需要这个来下载文件，如果没有则安装它

Dropbox Chooser允许用户从其保管箱帐户中选择任何文件，并返回所选文件的共享链接，以便：

    //Ask SwiftyDropbox if the user is logged in

    if DropboxClientsManager.authorizedClient != nil{


    // Use this from Dropbox chooser to open a view controller that allow the user select the file
    //DBChooserLinkTypeDirect <--- it has to be this parameter, there is another one but is useless for our purpose

    DBChooser.default().open(for: DBChooserLinkTypeDirect, from: self, completion: { (results) in

                //Here starts the completion block of Chooser

                if let resultado = results{ //Obtain the results 

                    var d = DBChooserResult() //Create a variable of DBChooserResult type
                    d = resultado[0] as! DBChooserResult //Get the result. Just one result because the user just can select ONE file (in this version just one, it may be more but I don't know how in this moment
                    print(d.name)
                    print(d.link)//The atributte link give us the url to download the file. 
    //If you paste it in your browser the download starts right away


                  //Use Alamofire to download the file from the url
                    Alamofire.request(d.link).responseData { response in

         //Get the data from the URL
                        if let data = response.result.value
                        {
                           //Here we have the data to do whatever we want, in my case I show the PDF file in a WebView
                            print("Data de Alamofire \(response.description)")
                            self.desplegarUrlEnWebview(datos: data, url: d.link)
                        }
                    }
                }

            })
        }else{

            //If the user is not logged in we use SwiftyDropbox to log in

            DropboxClientsManager.authorizeFromController(UIApplication.shared, controller: self, openURL: { (url) in

                UIApplication.shared.open(url, options: [:], completionHandler: nil)
            })
        }
