TableViewCell is not clickable with one finger tap, but it is with two fingers

Closed 3 years ago.
I'm not receiving the touches. It shows the selection on the iPhone's screen, but it doesn't performs the method didSelectRow.
usersTV.register(UserCell.self, forCellReuseIdentifier: "userCell")
usersTV.dataSource = self
usersTV.delegate = self
usersTV.backgroundColor = .clear
usersTV.separatorColor = .white
usersTV.translatesAutoresizingMaskIntoConstraints = false
usersTV.isHidden = true
usersTV.tableFooterView = UIView()
usersTV.isUserInteractionEnabled = true
usersTV.isEditing = false
usersTV.allowsSelection = true
usersTV.allowsSelectionDuringEditing = false
usersTV.allowsMultipleSelection = false
usersTV.allowsMultipleSelectionDuringEditing = false
usersTV.delaysContentTouches = false
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
Everything is programatically written.
The cells are custom with 3 labels and added constraints.
What could be the problem ?
UPDATE:
class UserCell : UITableViewCell{
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
let viewsDict = ["userName":userName,"field1":field1,"field2":field2]
contentView.superview?.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "H:|-8-[userName(120)]-8-[field1]-8-[field2(120)]-8-|", options: NSLayoutFormatOptions(rawValue: 0), metrics: nil, views: viewsDict))
contentView.superview?.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "V:|[userName]", options: NSLayoutFormatOptions(rawValue: 0), metrics: nil, views: viewsDict))
contentView.superview?.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "V:|[field1]", options: NSLayoutFormatOptions(rawValue: 0), metrics: nil, views: viewsDict))
contentView.superview?.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "V:|[field2]", options: NSLayoutFormatOptions(rawValue: 0), metrics: nil, views: viewsDict))
UPDATE:
The didSelectRow method works only if you tap with 2 fingers...

Answer 1

TableViewCell is not clickable with one finger tap, but it is with two fingers
The answer of this question helped me. I've set GestureRecognizer on the main view. When I remove it the problem fixes.

Answer 2

I think this code will help you.If not,There may be a issue with the label constraints.
#IBOutlet weak var UserTV: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
UserTV.register(UserCell.self, forCellReuseIdentifier: "userCell")
UserTV.dataSource = self
UserTV.delegate = self
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 10
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let vc :UserCell = self.UserTV.dequeueReusableCell(withIdentifier: "userCell") as! UserCell
vc.textLabel?.text = "Index: \(indexPath.row)"
vc.backgroundColor = UIColor.red
return vc
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print("Slected \(indexPath.row)")
}

First of all, here is my comment on your code:
No need to go much complex for this easy task.
Don't forgot to set delegate and datasource properly.
No need to use Visual Format way to set constraints, use Anchors.
My suggestion for you:
Always try to use UICollectionView instead of UITableView.
class SampleTableViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
// MARK: - Variables
lazy private var listTableView: UITableView = {
let tableView = UITableView()
tableView.translatesAutoresizingMaskIntoConstraints = false
tableView.delegate = self
tableView.dataSource = self
return tableView
}()
// MARK: - View LifeCycle
override func viewDidLoad() {
super.viewDidLoad()
initialSetup()
}
// MARK: - Private Methods
private func initialSetup() {
view.backgroundColor = .white
view.addSubview(listTableView)
listTableView.leftAnchor.constraint(equalTo: view.leftAnchor).isActive = true
listTableView.rightAnchor.constraint(equalTo: view.rightAnchor).isActive = true
listTableView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
listTableView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
listTableView.register(UITableViewCell.self, forCellReuseIdentifier: "listCell")
}
// MARK: - TableView Methods
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 20
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 50
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "listCell", for: indexPath)
cell.textLabel?.text = "Table Row - \(indexPath.row)"
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print(#function)
}
