i cannot download the array of images to the app i n swift , what is the best way to download the number of image to sorted into tableview from the Files in the backend .

Pranav, 

thanks for you kind support , i have fix the issue it was with the _acl in the backend not with the download function 

i use the metadata . 

Now you can mark this as answered :)

 let value_ = KCSMetadata()

 value_.setGloballyReadable(true)

Thanks,

i think the issue is on the Files on the backend , check this SC , i have add the ext. as the drag drop image i ask you before and its work with it but with the username is not working still the same could you check the SC i think the issue in _acl how can i fix it .

agin its only download the Active user Image .

this the second method which is i am using specific column have uploaded attribute by user 

as the SC the print result give me the correct IDs in the Files backend but the download is only one and the one downloaded is the only active user image .

Pranav, 

 Thank you fro your reply .

1- yes my images have no ext. but when i request to download the image  for the active user its working fine .

2- yes i have try this also  KCSFileStore.downloadFileByQuery() the same 

i have two method of download i have try .

first one i download the images regarding to the filename_ which the same of the user Name i have in the backend file with no ext and its work if i call the active user image only other images give me 0 .

second try the create Column name "Img_Id" having attribute by assigning the user ID to this column 

the problem in both method that the code download only the active user image or if i use the option .KCSAll its download  the active user with the image in back end file all .

note :- the image in the files has been uploaded from the User in app .

i am using this code to inquiry the names of the Images 

    func NumberOfCells(Name0FRest : String)  {

        let collection = KCSCollection(fromString: "Comments", ofClass: NSDictionary.self)

        DownCells.storeComments = KCSCachedStore(collection: collection , options: [ KCSStoreKeyCachePolicy : KCSCachePolicy.LocalFirst.rawValue ])

        let query = KCSQuery()

        DownCells.storeComments.queryWithQuery(

            query,

            withCompletionBlock: { (objectsOrNil: [AnyObject]!, errorOrNil: NSError!) -> Void in

                if errorOrNil == nil {

                    //extract just the Value field from the entities

                    for d in objectsOrNil as! [NSDictionary] {

                        let userName = d.valueForKey("User_Name") as? String

                        let valueValue = d.valueForKey("Rest_Name") as? String

                        let CommentsValue = d.valueForKey("Comments") as? String

                      let user_img = d.valueForKey("Img_Id") as? String

                        // check if value nil or not to avoid the download error 

                        if valueValue != nil  {

                            if valueValue == Name0FRest {

                                self.valueValue_.append(valueValue!)

                                if userName != nil  {

                                    if valueValue == Name0FRest {

                                        // fill the array of Users Name

                                        self.userName_.append(userName!)

                                        // fill the array of Comments

                                        self.CommentsValue_.append(CommentsValue!)

                                        // fill the array of Images Name

                                        self.user_img_Id.append(user_img!)

                                    }

                                }

                            }

                        }

                    }

                    // insert the names of the user comments to doownload ther images

                    self.refreshControl.endRefreshing()

                    self.tableView.reloadData()

// here i add the array of the names that i download it to the function to download the images by name . 

                    self.DownloadImages(self.user_img_Id)

 ----------

then i use the this code to download the images with the extracted value.

 and the result is as per below , the names are correct but the issue is the code only download the last name 

 and if i use the option .KCSAll 

this the result

this the second method i have test that i assign the array to be downloaded 

    func DownloadImages(ImagesId : [String]) -> Void {

        // var fileUrl = NSURL()

        // Sequence the array name by name to requested from the Backend

          //  print(Names)

            let query = KCSQuery(onField: KCSFileFileName, usingConditional: .KCSIn, forValue: ImagesId as NSObject)

            print(ImagesId)

            KCSFileStore.downloadDataByQuery(query,completionBlock: { (downloadedResources: [AnyObject]!, error: NSError!) -> Void in

                if error == nil {

                  print(downloadedResources.count)

                } else {

                    NSLog("Got an error: %@", error)

                }

                },progressBlock: nil)

    }

and this the result 

["ramyal", "ramyal", "Ram"]

Pranav,

 thank your for reply , the issue still the same the function only download the active user this what appear to me .

what i need is to download all the images for the specific users i give to the function .

Thanks , 

this the new code i am using but the issue is only downloading the last element of the array 

---------------------------------------------------------------------------

   func DownloadImages(ImagesId : [String]) -> Void {

        var fileUrl = NSURL()

 //ImagesId its the array of the name i requested 

        for Names in  ImagesId {

        KCSFileStore.downloadFileByName(Names,completionBlock: { (downloadedResources: [AnyObject]!, error: NSError!) -> Void in

                if error == nil {

                    for Counting in ImagesId {

  print(Counting)// counting the elements in the array to do the below function 

// till here every things is OK but when download image its only download the last element ??

                    if let  Pic = downloadedResources as? [KCSFile]{

                        for picsID in Pic{

                            fileUrl = picsID.localURL

                            self.image.append(UIImage(contentsOfFile: fileUrl.path!)!)

// the below code for showing and reload the cell on the table view 

                            self.changer = true 

                            self.tableView.reloadData()

                        }

                    }

                }

this the code i am using as per with the screenshot the the value are saved in array for the looking value with the files but the download result is only one image ? how i can download the images that i need in array .
