I have tableview in which there is list item and every cell possess a button, I want to fix the text and color of the button based on a boolean value retrieved from firestore, every cell's button have certain text and color based on that value only, I know the syntax to set the text and color for the button in swift, I am just not able to do on the basis of the value from the firestore, below is the code
code for retrieving the list, concerned value is checkl1value
func getComments() {
//print(postId + "received")
let commentsRef = Firestore.firestore().collection("posts").document(postId).collection("comments")
commentsRef.getDocuments { (snapshot, error) in
if let error = error {
print(error.localizedDescription)
} else {
if let snapshot = snapshot {
for document in snapshot.documents {
let data = document.data()
let username = data["comment_author_username"] as? String ?? ""
let comment = data["comment_author_comment"] as? String ?? ""
let spinnerC = data["comment_author_spinnerC"] as? String ?? ""
let fullname = data["comment_author_fullname"] as? String ?? ""
let email = data["comment_author_email"] as? String ?? ""
let commentUserImageUrl = data["comment_user_image"] as? String ?? ""
let commentuser_id = data["comment_author_id"] as? String ?? ""
self.checkl1value = data["l1"] as? DarwinBoolean
let newComment = Comment(_documentId: document.documentID, _commentAuthorUsername: username, _commentAuthorFullName: fullname, _commentAuthorComment: comment, _commentUserImage: commentUserImageUrl, _commentAuthorSpinnerC: spinnerC, _commentAuthorId:commentuser_id )
self.comments.append(newComment)
}
self.tableView.reloadData()
}
}
}
}
Code for cellForRowAt
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "CommentCell", for: indexPath) as! CommentCell
cell.commentLikebutton.tag = indexPath.row
cell.commentLikebutton.addTarget(self, action: #selector(likeaction1(_:)), for: .touchUpInside)
if checkl1value == true {
cell.commentLikebutton.setTitle("Text1", for: .normal)
// cell.commentLikebutton.backgroundColor = UIColor(red: 17.0/255.0, green: 119.0/255.0, blue: 151.0/255.0, alpha: 1.0)
cell.commentLikebutton.backgroundColor = UIColor.red
//cell.commentLikebutton.backgroundColor = UIColor?.red()
}
else{
cell.commentLikebutton.setTitle("Text2", for: .normal)
}
cell.set(comment: comments[indexPath.row])
return cell
}
Add something like this on the top of cellForRowAt
let thisComment = self.comments[indexPath.row]
let checkl1value = thisComment.checkl1value
I think the error is that your checkl1Value always get changed with the value of the last item in the array. You can do something like this:
var booleanValues = [DarwinBoolean]()
func getComments() {
let commentsRef = Firestore.firestore().collection("posts").document(postId).collection("comments")
commentsRef.getDocuments { (snapshot, error) in
if let error = error {
print(error.localizedDescription)
} else {
if let snapshot = snapshot {
for document in snapshot.documents {
let data = document.data()
let username = data["comment_author_username"] as? String ?? ""
let comment = data["comment_author_comment"] as? String ?? ""
let spinnerC = data["comment_author_spinnerC"] as? String ?? ""
let fullname = data["comment_author_fullname"] as? String ?? ""
let email = data["comment_author_email"] as? String ?? ""
let commentUserImageUrl = data["comment_user_image"] as? String ?? ""
let commentuser_id = data["comment_author_id"] as? String ?? ""
// self.checkl1value = data["l1"] as? DarwinBoolean
booleanValues.append(data["l1"] as? DarwinBoolean ?? false)
let newComment = Comment(_documentId: document.documentID, _commentAuthorUsername: username, _commentAuthorFullName: fullname, _commentAuthorComment: comment, _commentUserImage: commentUserImageUrl, _commentAuthorSpinnerC: spinnerC, _commentAuthorId:commentuser_id )
self.comments.append(newComment)
}
self.tableView.reloadData()
}
}
}
}
CellForRowAt:
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

I tried to update TableView cell when click cell from CollectionView with key word of class.
For example, when I click "all", it should perform all data.
When I click "a", it should perform class with "a".
It looks like all perfect until I scroll down TableView.
All data display which is not my intension, it should only show specify data even scroll up/down TableView.
Is it related to dequeueReusableCell issue?
I use FMDB to query data when click CollectionView cell.
I attach gif
and hope it could be better to understand my problem.
Can someone help me out with this please? Thanks.

my table has 03 sections, 1) has no row, 2) has no row 3) has 04 segcons.
when segcon changed then the data changes then reload the section 03. the issue is when the data is not fill the screen then the table moves down automatically. what i want is, the table will not move down automatically eventhough the data is not enough to fill the screen.
i try to use the footer but no help

You can get all data already ordered alphabetically
databaseRef.child("Books").queryOrdered(byChild: "title").observe(.childAdded, with: { snapshot in
var snapshotValue = snapshot.value as? NSDictionary
let title = snapshotValue!["title"] as? String
snapshotValue = snapshot.value as? NSDictionary
....
}
or sort your array before reload the tableView
var sortedArray = swiftArray.sorted { $0.title.localizedCaseInsensitiveCompare($1.title) == ComparisonResult.orderedAscending }
Sample structure
for sorting data according to searchBar I had used an dictionary that having all my snapshot and I compared my searchBar text in that dict and after sorting reloaded tableView here is code that you can have a look at
//method to get all user Details in a dict
func getEmail() {
let databaseRef = Database.database().reference().child("users")
databaseRef.observe(.value, with: { (snapshot) in
if snapshot.exists(){
self.postData = snapshot.value as! [String : AnyObject]
let dictValues = [AnyObject](self.postData.values)
self.sarchDict = dictValues
}
})
}
//search bar delegate
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
if self.mySearchBar.text!.isEmpty {
// set searching false
self.isSearching = false
}else{
// set searghing true
self.isSearching = true
self.names.removeAll()
self.uidArray.removeAll()
self.imageUrl.removeAll()
for key in self.sarchDict {
let mainKey = key
//I am making query against email in snapshot dict
let str = key["email"] as? String
//taking value of email from my dict lowerCased to make query as case insensitive
let lowercaseString = str?.lowercased()
//checking do my any email have entered letter or not
if(lowercaseString?.hasPrefix(self.mySearchBar.text!.lowercased()))!{
//here I have a check so to remove value of current logged user
if ((key["uID"] as! String) != (Auth.auth().currentUser?.uid)!){
//If value is found append it in some arrays
self.imageUrl.append( key["profilePic"] as! String )
self.names.append( key["name"] as! String )
self.uidArray.append( key["uID"] as! String )
//you can check which values are being added from which key
print(mainKey)
}
}
}
//reload TableView here
}
}
//TableView
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
cell = self.myTableView.dequeueReusableCell(withIdentifier: "Cell")!
if self.isSearching == true {
let imageView = (cell.viewWithTag(1) as! UIImageView)
imageView.setRounded()
if imageUrl[indexPath.row] != "" {
self.lazyImage.showWithSpinner(imageView:imageView, url:imageUrl[indexPath.row])
}
else{
imageView.image = UIImage(named: "anonymous")
}
(cell.contentView.viewWithTag(2) as! UILabel).text = self.names[indexPath.row]
}
else {
}
return cell
}
I'm sure this will be helpful to some using FireStore. Here I'm just setting my reference to point to the right collection. "name" is my field I wish to search by and is greater than will be checked chronologically on my string. The further they type the more defined the search results are.
static func searchForProgramStartingWith(string: String) {
let programsRef = db.collection("programs")
programsRef.whereField("name", isGreaterThan: string).limit(to: 10).getDocuments { (snapshot, error) in
if error != nil {
print("there was an error")
} else {
let shots = snapshot?.documents
for each in shots! {
let data = each.data()
let name = data["name"]
print("The name is \(name!)")
}
}
}
}
