I have my upload code here
import UIKit
import Firebase
class ChatViewController: UIViewController {
let chatRef = FIRDatabase.database().reference().child("chat")
let userUid = FIRAuth.auth()?.currentUser?.uid
var userName = ""
#IBOutlet weak var topBar: UINavigationItem!
#IBOutlet weak var containerView: UIView!
#IBOutlet var inputTextField: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
topBar.title = "Chat Log Controller"
FIRDatabase.database().reference().child("users/\(userUid!)/name").observe(.value) { (snap: FIRDataSnapshot) in
self.userName = (snap.value! as! String).description
}
}
#IBAction func handleSend(_ sender: AnyObject) {
let childChatRef = chatRef.childByAutoId()
let message = inputTextField.text!
childChatRef.child("text").setValue(message)
print(inputTextField.text)
}
#IBAction func handleSendByEnter(_ sender: AnyObject) {
let childChatRef = chatRef.childByAutoId()
let message = inputTextField.text!
print(userName)
childChatRef.child("name").setValue(userName)
childChatRef.child("text").setValue(message)
print(inputTextField.text)
}
}
text is successfully uploaded But
It doesn't print userName and doesn't upload it to Firebase Database
But username is nut nil!
Try to use your observer code as,
ref.observeSingleEventOfType(.Value, withBlock: { snapshot in
}
Just take self.username = snap.value! as! String
It will solve your problem.

And here my Account View Controller
import UIKit
import FirebaseAuth
import FirebaseFirestore
import Firebase
class AccountViewController: UIViewController {
#IBOutlet weak var FNameTextField: UITextField!
#IBOutlet weak var LNameTextField: UITextField!
#IBOutlet weak var EmailTextField: UITextField!
#IBOutlet weak var PasswordTextField: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func logoutbutton(_ sender: Any) {
do{
try Auth.auth().signOut()
performSegue(withIdentifier: "signout", sender: nil)
}
catch{
print(error)
}
}
}
You can use this function:
func updateFirestoreUserProfile(uid: String, data: [String:Any]) {
Firestore.firestore().collection("users").document(uid).updateData(data) { err in
if let err = err {
print("Error updating document: \(err) ")
}
else {
print("Document successfully updated")
}
}
}
You can use the function like this:
let data = [
"FirstName": name,
"LastName": surname
]
updateFirestoreUserProfile(uid: user.uid, data: data)
Tell me what can be a mistake. I have 6 columns, two columns belong to TableViewCell. The other 4 belong to the ViewController. How do I tie the rows correctly so that the match information matches its row in TableViewCell.
import UIKit
import Parse
class DetailTennisViewController: UIViewController {
#IBOutlet weak var imageTennis: UIImageView!
#IBOutlet weak var outClose: UIButton!
#IBOutlet weak var titleTennis: UILabel!
#IBOutlet weak var textTennis: UITextView!
#IBOutlet weak var progTennis: UILabel!
#IBAction func closeOut(_ sender: Any) {
dismiss(animated: false, completion: nil)
}
var tenises : Tennis?
func configureButton() {
outClose.layer.cornerRadius = 0.5 * outClose.bounds.size.width
outClose.clipsToBounds = true
}
override func viewDidLoad() {
super.viewDidLoad()
loadTennis()
configureButton()
}
func loadTennis () {
let qwery = PFQuery(className: "tennis")
qwery.getFirstObjectInBackground() { (object,error) ->Void in
if error == nil {
self.textTennis.text = object!["textTen"] as? String
self.progTennis.text = object!["progTen"] as? String
self.titleTennis.text = object!["titleTen"] as? String
let imageFile = object!["tenImage"] as? PFFile
imageFile?.getDataInBackground() { (data:Data?, error:Error?)->Void in
if error == nil {
if let imageData = data {
self.imageTennis.image = UIImage(data: imageData)
}
}
}
}
}
}
}

startCall func not working
You need to define delegate in viewcontroller' ViewDidLoad
let objOardView = CardView() // this is only test purpose
objOardView.socketdelegate = self
Hi guys I'm really having troubles trying to pass data from a tableview to another view controller. I have a tableview that displays a list of every user but when I click on a user it goes to the next view controller without showing any data of that particular user. The code below is pretty much the same from an example I followed but for some reason its not working for me. Please help, I've tried searching for solutions but can't find anything. Im also using firebase to store and retrieve my data. Thanks in advance
#IBOutlet weak var searchTableView: UITableView!
var profiles = [user]()
var ref: FIRDatabaseReference!
override func viewdidload(){
databaseRef = FIRDatabase.database().reference()
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
performSegue(withIdentifier: "guestSegue", sender: self)
self.searchTableView.deselectRow(at: indexPath as IndexPath, animated: true)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "guestSegue" {
if let indexpath = searchTableView.indexPathForSelectedRow {
let guestVC = segue.destination as! guestProfileViewController
guestVC.ref = profiles[indexpath.row].ref
}
}
}
user array
class User {
var backgroundProfileImage: String!
var fullName: String!
var profilePic: String!
var ref: FIRDatabaseReference!
var key: String
init(backgroundProfileImage: String, fullName: String, profilePic: String, key: String = ""){
self.backgroundProfileImage = backgroundProfileImage
self.fullName = fullName
self.profilePic = profilePic
self.key = key
self.ref = FIRDatabase.database().reference()
}
init(snapshot: FIRDataSnapshot){
self.backgroundProfileImage = value["backgroundProfileImage"] as! String!
self.fullName = (snapshot.value as! NSDictionary)["fullName"] as! String
self.profilePic = (snapshot.value as! NSDictionary)["profilePic"] as! String
self.uid = (snapshot.value as! NSDictionary)["uid"] as! String!
self.key = snapshot.key
self.ref = snapshot.ref
}
guestViewController
class guestProfileViewController: UIViewController, UINavigationControllerDelegate {
#IBOutlet weak var profileImage: UIImage!
#IBOutlet weak var backgroundProfileImage: UIImageView!
#IBOutlet weak var fullNameLabel: UILabel!
var ref: FIRDatabaseReference?
override func viewDidLoad() {
super.viewDidLoad()
ref = FIRDatabase.database().reference()
loadProfileData()
}
func loadProfileData(){
if let ref = ref {
ref.observe(.value, with: { (user) in
let user: User = User(snapshot: user)
self.fullNameLabel.text = user.fullName
self.profileImage.sd_setImage(with: URL(string: user.profilePic), placeholderImage: UIImage(named: "default"))
self.backgroundProfileImage.sd_setImage(with: URL(string: user.backgroundProfileImage), placeholderImage: UIImage(named: "default_1"))
})
}
}
}
ref is being set in viewDidLoad() of guestProfileViewController. Try removing that bit as it seems like you want ref to equal the User's ref.
Sorry for my English.
I have many problems in achieving data persistence after call the webservice .
Everything works correctly but I need to use that data in other methods .
As seen in the image once charge data on the screen then I want to give the user the option to use them well or load new data . But not as saving the data recovery webservice .
I was trying to use NSUserDefault but neither work .
From already thank you very much , any response is helpful .
