Update label in custom UITableView Cell

问题

I need to Update an label by clicking on an Button in the same cell. Why does my code doesn't work ?

@IBAction func actionFaveUnfave(sender: AnyObject) {
    let cell = self.tableView.cellForRowAtIndexPath(sender.indexPath)
    println(cell?.labelFavedTimes)

   cell.labelFavedTimes = "22"}

回答1:

cell?.labelFavedTimes.text = "22"

BTW self.tableView.cellForRowAtIndexPath(sender.indexPath) can return nil if cell is not visible

回答2:

I solved the problem by using superview...here is my solution:

    let button = sender as! UIButton
    let view = button.superview!
    let cell = view.superview as! TableViewCellHome

    let indexPath = tableView.indexPathForCell(cell)
    println(indexPath)
    if(indexPath != nil){
        var cell = self.tableView.cellForRowAtIndexPath(indexPath!) as! TableViewCellHome
        cell.labelFavedTimes.text = favedTimesInt +  " Faves"
    }

回答3:

cell.labelFavedTimes.text = "22"
