button inside cellView I can't know which cell user pressed - swift

Question

I have custom cell in tableView
inside it I have a button , I want when user click on the button push viewController, how I can do that and how I can know which cell user use its button, because here not didSelectRowAtIndexPath

Answer 1

Create a custom button class
class CustomButton: UIButton {
var indexPath: NSIndexPath!
}
In your custom cell create the button of the CustomButton type add the following lines in cellForRowAtIndexPath
cell.yourCustomButton.indexPath = indexPath
Define IBAction like this
#IBAction func customButtonClicked(sender: CustomButton) {
let indexPath: NSIndexPath = sender.indexPath
// Do whatever you want with the indexPath
}

Answer 2

Add Tag of button in Cell and add Target for your transition Function
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier(reuseIdentifier) as! CustomCell
cell.button.tag = indexPath.row
cell.button.addTarget(self, action: #selector( self.transitonMethod ), forControlEvents: UIControlEvents.TouchUpInside)
return cell
}
Fetch indexPath from tag of sender Button and Fetch Cell for this indexPath.Push your controller on your navigation controller
func transitonMethod(sender: AnyObject){
let indexPath = NSIndexPath.init(index: sender.tag)
let cell = tableView.cellForRowAtIndexPath(indexPath)
self.navigationController?.pushViewController(yourController, animated: true)
}

Answer 3

In cellforRow method of tableview:
1) set tag of your button e.g. yourButton.tag = indexpath.row
2) set target method of yourbutton e.g.buttonPressed(sender:UIButton)
3) Now in that target method you will get indexpath.row by sender.tag

Answer 4

Declare an IBAction as follow as suggested in IOS 7 - How to get the indexPath from button placed in UITableViewCell :
#IBAction func didTapOnButton(sender: UIButton) {
let cell: UITableViewCell = sender.superview as! UITableViewCell
let indexPath: NSIndexPath = self.tableView.indexPathForCell(cell)
// Do anything with the indexPath
}
Or the other method :
#IBAction func didTapOnButton(sender: UIButton) {
let center: CGPoint = sender.center
let rootViewPoint: CGPoint = sender.superview?.convertPoint(center, toView: tableView)
let indexPath: NSIndexPath = tableView.indexPathForRowAtPoint(rootViewPoint!)
print(indexPath)
}
Then work with that indexPath to do whatever you need.
