func buttonAction(sender:UIButton!)
    {
        var position: CGPoint = sender.convertPoint(CGPointZero, toView: self.tablevw)
        let indexPath = self.tablevw.indexPathForRowAtPoint(position)
        let cell: TableViewCell = tablevw.cellForRowAtIndexPath(indexPath!) as TableViewCell
        println(indexPath?.row)
        println("Button tapped")
    }

Swift 2更新

下面是如何找出哪个按钮被点击+从该按钮的indexPath发送数据到另一个ViewController。我认为这是大多数人的重点!

@IBAction func yourButton(sender: AnyObject) {


     var position: CGPoint = sender.convertPoint(CGPointZero, toView: self.tableView)
        let indexPath = self.tableView.indexPathForRowAtPoint(position)
        let cell: UITableViewCell = tableView.cellForRowAtIndexPath(indexPath!)! as
        UITableViewCell
        print(indexPath?.row)
        print("Tap tap tap tap")

    }

对于那些使用ViewController类并添加tableView的人，我使用的是ViewController而不是TableViewController，所以我手动添加了tableView以便访问它。

下面是当点击按钮并传递单元格的indexPath.row时，将数据传递给另一个VC的代码

@IBAction func moreInfo(sender: AnyObject) {

    let yourOtherVC = self.storyboard!.instantiateViewControllerWithIdentifier("yourOtherVC") as! YourOtherVCVIewController



    var position: CGPoint = sender.convertPoint(CGPointZero, toView: self.tableView)
    let indexPath = self.tableView.indexPathForRowAtPoint(position)
    let cell: UITableViewCell = tableView.cellForRowAtIndexPath(indexPath!)! as
    UITableViewCell
    print(indexPath?.row)
    print("Button tapped")


    yourOtherVC.yourVarName = [self.otherVCVariable[indexPath!.row]]

    self.presentViewController(yourNewVC, animated: true, completion: nil)

}

在Swift 4.2和iOS 12中，你可以从以下5个完整的例子中选择一个来解决你的问题。

# 1。使用UIView的convert(_:to:)和UITableView的indexPathForRow(at:)

import UIKit

private class CustomCell: UITableViewCell {

    let button = UIButton(type: .system)

    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)

        button.setTitle("Tap", for: .normal)
        contentView.addSubview(button)

        button.translatesAutoresizingMaskIntoConstraints = false
        button.centerXAnchor.constraint(equalTo: contentView.centerXAnchor).isActive = true
        button.centerYAnchor.constraint(equalTo: contentView.centerYAnchor).isActive = true
        button.topAnchor.constraint(equalToSystemSpacingBelow: contentView.topAnchor, multiplier: 1).isActive = true
        button.leadingAnchor.constraint(greaterThanOrEqualToSystemSpacingAfter: contentView.leadingAnchor, multiplier: 1).isActive = true
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

}

import UIKit

class TableViewController: UITableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.register(CustomCell.self, forCellReuseIdentifier: "CustomCell")
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 3
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCell", for: indexPath) as! CustomCell
        cell.button.addTarget(self, action: #selector(customCellButtonTapped), for: .touchUpInside)
        return cell
    }

    @objc func customCellButtonTapped(_ sender: UIButton) {
        let point = sender.convert(CGPoint.zero, to: tableView)
        guard let indexPath = tableView.indexPathForRow(at: point) else { return }
        print(indexPath)
    }

}

# 2。使用UIView的convert(_:to:)和UITableView的indexPathForRow(at:) (alternative)

这是前一个例子的替代方案，我们将nil传递给addTarget(_:action:for:)中的目标参数。这样，如果第一个响应器没有实现该操作，它将被发送到响应器链中的下一个响应器，直到找到适当的实现。

import UIKit

private class CustomCell: UITableViewCell {

    let button = UIButton(type: .system)

    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)

        button.setTitle("Tap", for: .normal)
        button.addTarget(nil, action: #selector(TableViewController.customCellButtonTapped), for: .touchUpInside)
        contentView.addSubview(button)

        button.translatesAutoresizingMaskIntoConstraints = false
        button.centerXAnchor.constraint(equalTo: contentView.centerXAnchor).isActive = true
        button.centerYAnchor.constraint(equalTo: contentView.centerYAnchor).isActive = true
        button.topAnchor.constraint(equalToSystemSpacingBelow: contentView.topAnchor, multiplier: 1).isActive = true
        button.leadingAnchor.constraint(greaterThanOrEqualToSystemSpacingAfter: contentView.leadingAnchor, multiplier: 1).isActive = true
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

}

import UIKit

class TableViewController: UITableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.register(CustomCell.self, forCellReuseIdentifier: "CustomCell")
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 3
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCell", for: indexPath) as! CustomCell
        return cell
    }

    @objc func customCellButtonTapped(_ sender: UIButton) {
        let point = sender.convert(CGPoint.zero, to: tableView)
        guard let indexPath = tableView.indexPathForRow(at: point) else { return }
        print(indexPath)
    }

}

# 3。使用UITableView的indexPath(for:)和委托模式

在这个例子中，我们将视图控制器设置为单元格的委托。当点击单元格的按钮时，它会触发对委托的适当方法的调用。

import UIKit

protocol CustomCellDelegate: AnyObject {
    func customCellButtonTapped(_ customCell: CustomCell)
}

class CustomCell: UITableViewCell {

    let button = UIButton(type: .system)
    weak var delegate: CustomCellDelegate?

    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)

        button.setTitle("Tap", for: .normal)
        button.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)
        contentView.addSubview(button)

        button.translatesAutoresizingMaskIntoConstraints = false
        button.centerXAnchor.constraint(equalTo: contentView.centerXAnchor).isActive = true
        button.centerYAnchor.constraint(equalTo: contentView.centerYAnchor).isActive = true
        button.topAnchor.constraint(equalToSystemSpacingBelow: contentView.topAnchor, multiplier: 1).isActive = true
        button.leadingAnchor.constraint(greaterThanOrEqualToSystemSpacingAfter: contentView.leadingAnchor, multiplier: 1).isActive = true
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

    @objc func buttonTapped(sender: UIButton) {
        delegate?.customCellButtonTapped(self)
    }

}

import UIKit

class TableViewController: UITableViewController, CustomCellDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.register(CustomCell.self, forCellReuseIdentifier: "CustomCell")
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 3
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCell", for: indexPath) as! CustomCell
        cell.delegate = self
        return cell
    }

    // MARK: - CustomCellDelegate

    func customCellButtonTapped(_ customCell: CustomCell) {
        guard let indexPath = tableView.indexPath(for: customCell) else { return }
        print(indexPath)
    }

}

# 4。使用UITableView的indexPath(for:)和一个委托闭包

这是前一个示例的替代方案，在前一个示例中，我们使用闭包而不是协议委托声明来处理按钮点击。

import UIKit

class CustomCell: UITableViewCell {

    let button = UIButton(type: .system)
    var buttontappedClosure: ((CustomCell) -> Void)?

    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)

        button.setTitle("Tap", for: .normal)
        button.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)
        contentView.addSubview(button)

        button.translatesAutoresizingMaskIntoConstraints = false
        button.centerXAnchor.constraint(equalTo: contentView.centerXAnchor).isActive = true
        button.centerYAnchor.constraint(equalTo: contentView.centerYAnchor).isActive = true
        button.topAnchor.constraint(equalToSystemSpacingBelow: contentView.topAnchor, multiplier: 1).isActive = true
        button.leadingAnchor.constraint(greaterThanOrEqualToSystemSpacingAfter: contentView.leadingAnchor, multiplier: 1).isActive = true
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

    @objc func buttonTapped(sender: UIButton) {
        buttontappedClosure?(self)
    }

}

import UIKit

class TableViewController: UITableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.register(CustomCell.self, forCellReuseIdentifier: "CustomCell")
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 3
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCell", for: indexPath) as! CustomCell
        cell.buttontappedClosure = { [weak tableView] cell in
            guard let indexPath = tableView?.indexPath(for: cell) else { return }
            print(indexPath)
        }
        return cell
    }

}

# 5。使用UITableViewCell的accessoryType和UITableViewDelegate的tableView(_:accessoryButtonTappedForRowWith:)

如果你的按钮是UITableViewCell的标准附件控件，在它上的任何点击都将触发调用UITableViewDelegate的tableView(_:accessoryButtonTappedForRowWith:)，允许你获得相关的索引路径。

import UIKit

private class CustomCell: UITableViewCell {

    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        accessoryType = .detailButton
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

}

import UIKit

class TableViewController: UITableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.register(CustomCell.self, forCellReuseIdentifier: "CustomCell")
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 3
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCell", for: indexPath) as! CustomCell
        return cell
    }

    override func tableView(_ tableView: UITableView, accessoryButtonTappedForRowWith indexPath: IndexPath) {
        print(indexPath)
    }

}

我总是使用标签。

你需要子类化UITableviewCell并从那里处理按钮按下。

usint[array addObject:yourButton];

在按按钮的方法

-

 (void)buttonPressedAction:(id)sender
{
    UIButton *button = (UIButton *)sender;

for(int i=0;i<[yourArray count];i++){

if([buton isEqual:[yourArray objectAtIndex:i]]){

//here write wat u need to do

}
}

我是这样做的。简洁明了:

- (IBAction)buttonTappedAction:(id)sender
{
    CGPoint buttonPosition = [sender convertPoint:CGPointZero
                                           toView:self.tableView];
    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:buttonPosition];
    ...
}
