我有一個帶有按鈕的表視圖，當其中一個按鈕被點擊時，我想使用indexpath.row。這是我目前所擁有的，但始終是0。var point = Int()func buttonPressed(sender: AnyObject) {
let pointInTable: CGPoint = sender.convertPoint(sender.bounds.origin, toView: self.tableView)
let cellIndexPath = self.tableView.indexPathForRowAtPoint(pointInTable)
println(cellIndexPath)
point = cellIndexPath!.row
println(point)}SWIFT：當單元格中的按鈕被點擊時，如何獲得indexpath.row？

guard let cell = sender.superview?.superview as? YourCellClassHere else {
return // or fatalError() or whatever}let indexPath = itemTable.indexPath(for: cell)UITableViewCell
class MyCell: UITableViewCell {
var button: UIButton!
var buttonAction: ((Any) -> Void)?
@objc func buttonPressed(sender: Any) {
self.buttonAction?(sender)
}}cellForRowAtIndexPath
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell") as! MyCell
cell.buttonAction = { sender in
// Do whatever you want from your button here. }
// OR cell.buttonAction = buttonPressed(closure: buttonAction, indexPath: indexPath)
// <- Method on the view controller to handle button presses.}indexPath
