I have a tableview with 2 textbox.text1 loads data on viewdidload function. for text2, the input is dates. I am using tableview didselectrow method to show datepicker. but when i select date from datepicker, it is printing in console but not added in textbox.

` override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    selectedIndex = indexPath.row
    let screenSize: CGRect = UIScreen.mainScreen().bounds
    datePickerContainer.frame = CGRectMake(20, 200, 290, 200.0)
    datePickerContainer.backgroundColor = UIColor.whiteColor()
    datePickerContainer.layer.borderWidth = 2.0
    datePickerContainer.layer.borderColor = UIColor.lightGrayColor().CGColor
    var pickerSize : CGSize = datePicker.sizeThatFits(CGSizeZero)
    datePicker.frame = CGRectMake(0.0, 20, pickerSize.width, 160)

    //datePicker.setDate(NSDate(), animated: true)
    //datePicker.maximumDate = NSDate()
    datePicker.datePickerMode = .Date

    datePicker.addTarget(self, action: "dateChangedInDate:", forControlEvents: UIControlEvents.ValueChanged)
    datePickerContainer.addSubview(datePicker)

    var doneButton = UIButton()
    doneButton.setTitle("Done", forState: UIControlState.Normal)
    doneButton.setTitleColor(UIColor.redColor(), forState: UIControlState.Normal)
    doneButton.addTarget(self, action: Selector("dismissPicker:"), forControlEvents: UIControlEvents.TouchUpInside)
    doneButton.frame    = CGRectMake(130.0, 160, 70.0, 37.0)

    datePickerContainer.addSubview(doneButton)

    self.view.addSubview(datePickerContainer)

}

func dateChangedInDate(sender:UIDatePicker){

    dateFormatter.dateStyle = .ShortStyle
    dateFormatter.dateFormat = "yyyy-MM-dd"
    let selectedDate = dateFormatter.stringFromDate(datePicker.date)
    firstIndex = NSIndexPath(forRow: selectedIndex, inSection: 0)

    let cell = tableView.cellForRowAtIndexPath(firstIndex) as! mytableviewcell
    cell.dateText.text = dateFormatter.stringFromDate(datePicker.date)

   // print(selectedDate)


}

` Any help is appreciated....

You should try making all updates to cells inside the tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell method. Make it so that the text of your label is bound to the DatePicker value. Then, inside your dataChangedWithDate() method, trigger a table update of the row in question using table.reloadRowsAtIndexPath(). Note that I'm assuming selectedIndex is an instance variable for your controller, so that you have access to it inside the dateChangedWithDate() method.

tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    // Dequeue the cell, perform all of your other tasks for laying out the cell
    // {...}

    // Bind the label's text to the DatePicker value
    dateFormatter.dateStyle = .ShortStyle
    dateFormatter.dateFormat = "yyyy-MM-dd"
    cell.dateText.text = dateFormatter.stringFromDate(datePicker.date)
}

func dateChangedInDate(sender:UIDatePicker){
    // Trigger table update for the selected row
    let indexPath = NSIndexPath(forRow: selectedIndex, inSection:0)
    tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.None)
}

create Variable to store data value.
// var dateTime = ""
//cellForIndexMethod
 cell.dateText.text = dateTime


func dateChangedInDate(sender:UIDatePicker){

 dateFormatter.dateStyle = .ShortStyle
 dateFormatter.dateFormat = "yyyy-MM-dd"
 dateTime = dateFormatter.stringFromDate(datePicker.date)
 let indexPath = NSIndexPath(forRow: selectedIndex, inSection:0)

 //Reload table
   self.tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.None)

}
