Swift: How to get row number of a button in each table row?

问题

Ive got a table. each table has its own custom button. when its pressed the following funtion runs

@IBAction func select(sender: UIButton) {

      anobject.itsproperty[the row?] = true
 }

how do I access which row the button was pressed from? so i can use that to access an array.

回答1:

In cellForRowAtIndexPathassign the row index to the tag property of the button.

cell.button.tag = indexPath.row

then get the tag to distinguish the rows

@IBAction func select(sender: UIButton) {
   if sender.tag == 0 {
     // do something with first row
   }
 }
