问题
I am uploading a single file in a table view cell using AFNetworking.
Uploading is working alright. But when I scroll my cell off view, the progress is gone or some times it displays different progress values like 20% or 50%, and again 30%.
This is my code:
//Tableview Cell configure
var cell : ChattingPhotoCell!
if message.vendorType == .Receiver {
//Receive Image message
cell = tableView.dequeueReusableCell(withIdentifier: "ReceiveChattingPhotoCell") as! ChattingPhotoCell
if cell == nil {
cell = Bundle.main.loadNibNamed("ReceiveChattingPhotoCell", owner: self, options: nil)?[0] as! ChattingPhotoCell
}
cell.reloadDelegate = self
cell.mDelegate = self
cell.accessoryType = cell.isSelected ? .checkmark : .none
cell.conficureImageCell(msg: message,indexPath: indexPath)
} else {
// Send Image Message
cell = tableView.dequeueReusableCell(withIdentifier: "SenderChattingPhotoCell") as! ChattingPhotoCell
if cell == nil {
cell = Bundle.main.loadNibNamed("SenderChattingPhotoCell", owner: self, options: nil)?[0] as! ChattingPhotoCell
}
cell.reloadDelegate = self
cell.mDelegate = self
cell.accessoryType = cell.isSelected ? .checkmark : .none
cell.conficureImageCell(msg: message,indexPath: indexPath)
}
//MyCell code
func conficureImageCell(msg:Message,indexPath:IndexPath) {
self.message = msg
self.indexPath = indexPath
if self.message.vendorType == .Sender {
self.senderCellConfigure()
} else {
self.receiverCellConfigure()
}
}
// sender configure methods
func senderCellConfigure() {
// Send Message
if message.upload == 1 {
self.btnRetry.isHidden = true
}else{
self.btnRetry.isHidden = false
}
if message.is_send == 0 && !self.message.isUploadMedia && message.upload != 1 {
let image = UIImage.init(contentsOfFile: documentDir.path)
if image != nil {
self.uploadImageToServer(ArrImage_Video: NSMutableArray.init(array: [image!]), strMsgType: "3")
}
}
if self.message.isUploadMedia {
self.progressView.isHidden = false
self.btnRetry.isHidden = true
} else {
self.progressView.isHidden = true
}
}
// MARK:- WebserviceCalling // Hiren
func uploadImageToServer(ArrImage_Video:NSMutableArray,strMsgType: String){
self.message.isUploadMedia = true
self.btnRetry.isHidden = true
if self.str_media_url.isBlank {
self.progressView.isHidden = false
let accessToken = Singleton.sharedSingleton.retriveFromUserDefaults(key:Global.kLoggedInUserKey.AccessToken)
print(accessToken!)
let param: NSMutableDictionary = NSMutableDictionary()
param.setValue(fromJID, forKey: "from_user_id")
param.setValue(toJID, forKey: "to_user_id")
param.setValue(strMsgType, forKey: "message_type")
param.setValue("ABC", forKey: "from_user_name")
param.setValue(UIDevice.current.model, forKey: "device_type")
param.setValue("897584acac541d73d5f01f294fe944ddb35b6f67ea894e9ac29b03c7da69ca48", forKey: "device_token")
param.setValue("jpeg", forKey: "file_type")
param.setValue("135", forKey: "message_id")
param.setValue(accessToken, forKey: "access_token")
AFAPIMaster.sharedAPIMaster.PostMediatoServer_chat(params: param, arrMedia: ArrImage_Video, showLoader: false, enableInteraction: true, viewObj: self, onSuccess: {
(DictResponse) in
let dictResponse: NSDictionary = DictResponse as! NSDictionary
let dictData: NSDictionary = dictResponse.object(forKey: "SuccessResponse") as! NSDictionary
let media_url = dictData.object(forKey: "media_url") as? String ?? ""
let media_id = dictData.object(forKey: "id") as? Int ?? 0
let thumb_image = dictData.object(forKey: "thumb_image") as? String ?? ""
print(media_url)
print(thumb_image)
DispatchQueue.main.async {
self.progressView.isHidden = true
let onChatMaster = OnChatMasterTable()
let messageObj = onChatMaster.getMessageFromDB(strMessageID: self.msgID, strFromUId: self.fromJID, strToUId: self.toJID)
messageObj.media_url = media_url
messageObj.thumb_url = thumb_image
messageObj.upload = 1
messageObj.message = self.imageName
messageObj.media_id = media_id
self.str_media_ID = String(media_id)
self.message.media_id = media_id
DBHelper.sharedInstance.queue?.inDatabase() {
db in
DBHelper.sharedInstance.chilaxDB.open()
let strUpdQuery = "UPDATE OnChat_Master SET upload = 1 , media_url = '\(media_url)', thumb_url = '\(thumb_image)' , media_id = \(media_id) where message_id = '\(messageObj.message_id)' AND from_user_id = '\(messageObj.from_user_id)' AND to_user_id = '\(messageObj.to_user_id)'"
DBHelper.sharedInstance.chilaxDB.executeUpdate(strUpdQuery, withArgumentsIn: [])
DBHelper.sharedInstance.chilaxDB.close()
}
//onChatMaster.updateMessageInDB(messsageObj: messageObj)
self.sendMediaDataToSender(media_url: media_url, thumb_image: thumb_image,strMediaId:self.str_media_ID)
self.message.isUploadMedia = false
}
}, displayProgress: {
(progress) in
DispatchQueue.main.async {
let progressTask : Float = Float((progress as! Progress).fractionCompleted)
print(progressTask)
self.progressView.setProgress(progressTask, animated: true)
}
}, onFailure: {
self.progressView.setProgress(0.0, animated: true)
self.progressView.isHidden = true
self.btnRetry.isHidden = false
self.message.isUploadMedia = false
})
} else {
self.sendMediaDataToSender(media_url: str_media_url, thumb_image: str_thumb_url, strMediaId: str_media_ID)
}
}
I reuse cell using table view deque methods. Any wrong in this code. Thanks in advanced.
