In Swift, I have created a custom cell with 3 labels and in which I have added a button or type UIButton. The button is displayed in each row of the table. When I click on the button I would like to save the indexPath of the row in which the button was pressed so I can replace the labels with different text. It is unclear to me how I could proceed. I would like to call the accessory button method (accessoryButtonTappedForRowWithIndexPath) if possible.

Thank you for any guidance.

One thing you could do is in cellForRowAtIndexPath, set the tag of the UIButton for that cell equal to the indexPath.row. When the button is tapped, it can trigger 

- (void) accessoryButtonTapped: (UIButton *) sender{
    int rowNum = sender.tag;
}

So now you have the rowNum of the button that was tapped. Not sure what you want to do with it though...

I think you have pretty much answered you own question but the trick is to set the button as an accessory view. For this accessory view, use a selector; e.g. didClickAccessoryView and then eventually call accessoryButtonTappedForRowWithIndexPath from there.

Here's an objective-c implementation for the same:

  • Thank you for your guidance. Here is what I tried: @IBAction func showSubcategoryEditor(sender: UIButton) { if let indexPath = tableView.indexPathForRowAtPoint(sender.frame) as NSIndexPath { tableView.delegate.accessoryButtonTappedForRowWithIndexPath(indexPath) } } override func tableView(tableView: UITableView, accessoryButtonTappedForRowWithIndexPath indexPath: NSIndexPath) { savedRow = indexPath.row self.performSegueWithIdentifier("SubcategorySegue", sender: self) } However I get the follwoing error message: – Syed Tariq Jan 31 '15 at 15:05
