Why is the top tableViewCell gray? - ios

Question

I am working with a UITableView in a normal UIViewController. For some reason, the text of the top cell in my TableView is always colored gray.
I have been trying to figure out what causes that cell to be gray, but don't know what it is. The data in my tableView is sourced from an array called fileList that gets refreshed during both viewWillAppear and viewDidAppear.
Why is the top cell always gray with this code?
(And it does happen both with nothing in the fileList and with many things in the fileList)
//MARK: - TableView
extension ViewController: UITableViewDataSource, UITableViewDelegate {
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if fileList.count == 0 {
return 1
} else {
return fileList.count
}
}
internal func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if fileList.count == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
cell.isUserInteractionEnabled = false
cell.accessoryType = UITableViewCellAccessoryType.none
cell.textLabel?.text = "No documents found"
cell.textLabel?.textAlignment = .center
cell.textLabel?.textColor = UIColor.black
return cell
} else {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
cell.isUserInteractionEnabled = true
cell.accessoryType = UITableViewCellAccessoryType.disclosureIndicator
cell.textLabel?.text = (fileList[indexPath.row])
cell.textLabel?.textAlignment = .left
cell.textLabel?.textColor = UIColor.black
return cell
}
}
}

Answer 1

There is no issue running your code , It's running fine for me.
Even setting cell.selectionstyle = .grey is not putting grey color to cell or text.
You have to be more clear about question .
1) What is grey? text color or cell color.
2) What is the code that you are hiding or doing else apart?
extension ViewController : UITableViewDelegate,UITableViewDataSource{
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int{
return fileList.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell{
let cell = tableView.dequeueReusableCell(withIdentifier: "cell")
let rowData = fileList[indexPath.row]
cell?.textLabel?.text = rowData
//cell?.isSelected = true
cell?.selectionStyle = .gray
cell?.isUserInteractionEnabled = true
cell?.accessoryType = UITableViewCellAccessoryType.disclosureIndicator
cell?.textLabel?.textAlignment = .left
cell?.textLabel?.textColor = UIColor.black // if let priceString = rowData[2] as? String { cell.priceLabel.text = "Price: $(priceString)" }
return cell!
}
// Number of sections in table
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}// Default is 1 if not implemented
}

I believe this is the same as the problem mentioned here. Try setting:
cell?.textLabel?.isEnabled = true`
in the if statement block for fileList.count == 0 after the line
cell.isUserInteractionEnabled = false
