如何识别哪个单元格被点击一次，哪个被点击了两次

Question

那里！我想知道哪个单元格被点击一次，哪个被点击两次。我有两个类，一个用于TableViewController，另一个用于TableViewCell。我想操纵有关触摸的单元格，但我无法获取它们的索引路径。

表视图控制器：

import UIKit
var elements: [[Int16]] = Array(repeating:Array(repeating:0, count:2), count:10)
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource
{
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return elements.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell
if(elements[indexPath.row][1] == 1) //if red
{
cell.Label.text = String(elements[indexPath.row][0] * 3)
cell.Circle.backgroundColor = UIColor.red
}
else //if blue
{
cell.Label.text = String(elements[indexPath.row][0])
cell.Circle.backgroundColor = UIColor.blue
}
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat
{
return UIScreen.main.bounds.height/10
}
override func viewWillAppear(_ animated: Bool)
{
for i in 0..<elements.count
{
elements[i][0] = Int16(Int(arc4random_uniform(10)))
elements[i][1] = Int16(Int(arc4random_uniform(2)))
}
Memory().save(entity: elements)
}
override func viewDidLoad()
{
super.viewDidLoad()
}
override func didReceiveMemoryWarning()
{
super.didReceiveMemoryWarning()
}
}

表视图单元格：

import UIKit
class TableViewCell: UITableViewCell
{
override func awakeFromNib()
{
super.awakeFromNib()
Circle.layer.cornerRadius = Circle.frame.width / 2
let singleTap = UITapGestureRecognizer(target: self, action: #selector(tappedOnce))
singleTap.numberOfTapsRequired = 1
addGestureRecognizer(singleTap)
let doubleTap = UITapGestureRecognizer(target: self, action: #selector(tappedTwice))
doubleTap.numberOfTapsRequired = 2
addGestureRecognizer(doubleTap)
singleTap.require(toFail: doubleTap)
singleTap.delaysTouchesBegan = true
doubleTap.delaysTouchesBegan = true
}
override func setSelected(_ selected: Bool, animated: Bool)
{
super.setSelected(selected, animated: animated)
}
@objc func tappedOnce(sender: AnyObject?)
{
print("1111111")
//Memory().reload(reload: x, I: x)
}
@objc func tappedTwice()
{
print("2222222")
}
@IBOutlet weak var Label: UILabel!
@IBOutlet weak var Circle: UIView!
}

在单元格内，我有一个标签，存储一个从 0 到 10 的随机数(标签(，旁边有一个圆圈 - 蓝色或红色(它们在开始时也是随机的(。如果圆圈为红色，则数字(标签(显示数字乘以 3。这一切都在那里。

现在。。。我想通过触摸单元格一次来更改数字，并通过触摸两次将其设为 0

TableViewController：

var elements: [[Int16]] = Array(repeating: Array(repeating:0, count:2), count:10)
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
//MARK: - UIViewController LifeCycle
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewWillAppear(_ animated: Bool) {
for i in 0..<elements.count {
elements[i][0] = Int16(Int(arc4random_uniform(10)))
elements[i][1] = Int16(Int(arc4random_uniform(2)))
}
Memory().save(entity: elements)
}

//MARK: - UITableView Delegate & DataSource
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return elements.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell
if elements[indexPath.row][1] == 1 {
cell.Label.text = String(elements[indexPath.row][0] * 3)
cell.Circle.backgroundColor = UIColor.red
}
else {
cell.Label.text = String(elements[indexPath.row][0])
cell.Circle.backgroundColor = UIColor.blue
}
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UIScreen.main.bounds.height/10
}
}

表视图单元格：

class TableViewCell: UITableViewCell {
@IBOutlet weak var Label: UILabel!
@IBOutlet weak var Circle: UIView!
private var tapCounter = 0
override func awakeFromNib() {
super.awakeFromNib()
Circle.layer.cornerRadius = Circle.frame.width / 2
let tap = UITapGestureRecognizer(target: self, action: #selector(tapAction))
addGestureRecognizer(tap)
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
@objc func tapAction() {
if tapCounter == 0 {
DispatchQueue.global(qos: .background).async {
usleep(250000)
if self.tapCounter > 1 {
self.tappedTwice()
}
else {
self.tappedOnce()
}
self.tapCounter = 0
}
}
tapCounter += 1
}
func tappedOnce() {
print("1111111")
}
func tappedTwice() {
print("2222222")
}
}
