Real Example of ListFolderContinue: method in Objective-C

Can someone please provide me a real example to show how listfoldercontinue: method works with listfolder: in objective-c or in swift? I have read 100 times the description of listfoldercontinue: method but can't understand in the right way. my folder always remains empty.

Previously I was using servermodified to know when the contents of a folder metdata changed.

To Dropbox team: Is it possible to get clientmodified and servermodified properties for DBFILESFolderMeta as well too just like we have clientModified and serverModified properties are available only for DBFILESFileMetadata?

Thank You

Ponky

The team just added a new sample to the README that shows how to use listFolder and listFolderContinue together:

https://github.com/dropbox/dropbox-sdk-obj-c#rpc-style-request

Hope this helps!

Thanks for the post! I don't believe we have a sample exactly like that available, so I'll send this along as a request for one.

I'm also sending this along as a request for modified times on non-file metadata, but I can't make any promises as to if or when that would be implemented and released. Using listFolder/listFolderContinue is a better way to keep track of changes.

To Dropbox Team,

Thank You for providing real example of listfolderContinue: method. Also now no need of timestamp property (like servermodified) for non-file type.

Thank You again,

Here is some example Swift code based on the Objective C code. This works for me to get all of the folders and directories including shared folders and directories.


    func listFolderContinueWithClient(client: DropboxClient, cursor: String) {
        client.files.listFolderContinue(cursor: cursor).response { response, error in
            if let result = response {
                print("entries in continue:")

                for entry in result.entries {
                    //if entry.name.hasSuffix(".fm") {
                    if let folder = entry as? Files.FolderMetadata {
                        print("directory")
                        print(entry.pathDisplay!)
                        self.dropBoxDirectoryArray.append(URL(fileURLWithPath: entry.pathLower!))
                    }else{
                        //print(entry.name)
                        print(entry.pathDisplay!)
                        self.dropBoxFileArray.append(URL(fileURLWithPath: entry.pathLower!))
                    }
                }
                if result.hasMore == true {
                    self.listFolderContinueWithClient(client: client, cursor: cursor)
                }else{
                    print("no more entries")
                }
            } else {
                print("Error: \(error!)")
            }
        }

    }

    // FIXME: - root controler button click
@objc func onClickBarButton(sender: UIBarButtonItem)
    {
        if sender.tag == 40 { // get from dropBox

            print("This is Directory Array")
            dump(self.dropBoxDirectoryArray)
            print("This is File array")
            dump(self.dropBoxFileArray)


            if let client = DropboxClientsManager.authorizedClient {
                client.files.listFolder(path: "", recursive: true).response { response, error in
                    if let result = response {
                        print("Folder contents:")

                        for entry in result.entries {
                            //if entry.name.hasSuffix(".fm") {

                                self.dropBoxDirectoryArray.append(URL(fileURLWithPath: entry.pathLower!))

                            }
                        }
                        if result.hasMore == true {
                            self.listFolderContinueWithClient(client: client, cursor: result.cursor)

                while let presentedViewController = topController!.presentedViewController {
                   topController = presentedViewController
                }

                DropboxClientsManager.authorizeFromController(UIApplication.shared,
                   controller: topController,
                   openURL: { (url: URL) -> Void in
                   UIApplication.shared.open(url, options: [:], completionHandler: nil)
                })
            }


        }

siddharth chauhan

in recursive call shouldn't it be

self.listFolderContinueWithClient(client: client, cursor: result.cursor)

instead of this

self.listFolderContinueWithClient(client: client, cursor: cursor)

Greg-DB

@siddharth chauhan Yes, you're correct. The app should use the latest returned cursor, which would be result.cursor there.
