search dropbox folder

Since you're using Swift, are you using the official SwiftyDropbox SDK? In that case, you'd use the search method in FilesRoutes. As long as the call succeeds, it will return a SearchResult. You can then use the SearchResult.matches, which is an array of SearchMatch. SearchMatch.metadata contains the FileMetadata for the match, which contains the name, pathDisplay, etc.

Give that a try and let us know if you run in to any issues.

I was trying the search func that returns a SearchResult but I couldnt get it working.  here is some of my code.

 hope this helps.  I really appreciate your help 

// MARK: - UISearchBarDelegate
    
    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
        var data = [String]()

        
        // IN HERE I WANT TO SEARCH MY APPS FOLDER IN DROPBOX AND POPULATE THE "data" STRING ARRAY WITH THE FILE NAMES OF ALL THE FILES IN THE FOLDER


        
        filtered = data.filter({ (text) -> Bool in
            let tmp: NSString = text as NSString
            let range = tmp.range(of: searchText, options: NSString.CompareOptions.caseInsensitive)
            return range.location != NSNotFound
        })
        
        if(filtered.count == 0){
            searchActive = false
        } else {
            searchActive = true
        }
 
        searchTableView.reloadData()
        
        // These next two lines dynamicaly adjust the Search TableView's height
        super.updateViewConstraints()
        self.searchTableViewHeightConstraint?.constant = self.searchTableView.contentSize.height
    }
 

I don't see in your code where you're attempting the search call. Can you share that part? Thanks!

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
        var data = [String]()

        data = search(path: "/stuckbykev/", query: searchText, start: 0, maxResults: 100, mode: .filename)
        
        filtered = data.filter({ (text) -> Bool in
            let tmp: NSString = text as NSString
            let range = tmp.range(of: searchText, options: NSString.CompareOptions.caseInsensitive)
            return range.location != NSNotFound
        })
        
        if(filtered.count == 0){
            searchActive = false
        } else {
            searchActive = true
        }

        searchTableView.reloadData()
        
        // These next two lines dynamicaly adjust the Search TableView's height
        super.updateViewConstraints()
        self.searchTableViewHeightConstraint?.constant = self.searchTableView.contentSize.height
    }
    
    @discardableResult open func search(path: String, query: String, start: UInt64 = 0, maxResults: UInt64 = 100, mode: Files.SearchMode = .filename) -> RpcRequest<Files.SearchResultSerializer, Files.SearchErrorSerializer> {
        
        
        return RpcRequest
    }

Thanks! Is that the exact code you're trying though? I don't see the Dropbox client object itself. You just seem to be calling a separate search method. Also, note that you need to implement the response callback. Just taking the return value won't give you what you're looking for.

The search method is an RPC-style call, so it would look like this:

https://github.com/dropbox/SwiftyDropbox#rpc-style-request

The Xcode autocomplete should also help with the parameters and response callback.

If you want to search for a particular string, that is the right method. Alternatively, if you want to just list everything in a folder, listFolder and listFolderContinue would be better.

ok here is my code now.  ive been trying a few different things. but the RPC request was throwing me off.  

// MARK: - UISearchBarDelegate
    
    var data = Array<Files.Metadata>()
    var namesList = [String]()
    var filtered = [String]()
    
    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
     
        // Verify user is logged into Dropbox
        if let dropboxClient = DropboxClientsManager.authorizedClient {
            
            // List folder contents and append to string array for return
            dropboxClient.files.listFolder(path: "stuckbykev/").response { response, error in
                if let response = response {
                    print(response)
                    
                    self.data = response.entries
                    for file in self.data {
                        self.namesList.append(file.name)
                    }
                } else if let error = error {
                    print(error)
                }
            }
        }
        
        print(namesList)
        
        filtered = namesList.filter({ (text) -> Bool in
            let tmp: NSString = text as NSString
            let range = tmp.range(of: searchText, options: NSString.CompareOptions.caseInsensitive)
            return range.location != NSNotFound
        })
        
        if(filtered.count == 0){
            searchActive = false
        } else {
            searchActive = true
        }

        searchTableView.reloadData()
        
        // These next two lines dynamicaly adjust the Search TableView's height
        super.updateViewConstraints()
        self.searchTableViewHeightConstraint?.constant = self.searchTableView.contentSize.height
    }

This is the error showing in the console, I think its a problem with my path string:

precondition failed: "stuckbykev/ must match pattern "\A(?:(/(.|[\r\n])*)?|(ns:[0-9]+(/.*)?))\z": file /Users/Kevin/Desktop/SwiftyDropbox-master/Source/SwiftyDropbox/PlatformNeutral/StoneValidators.swift, line 9

thanks again for all your help Greg!
