working with cell on tableview using swift 2

Question

I am developing a app using Swift 2. In my app I am parsing JSON data to a table view. When I tap a cell it successfully moves to another view controller but I am unable to fetch the json data.

This is the code in my view controller:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath){
    var cell = self.TableView.dequeueReusableCellWithIdentifier("Cell",forIndexPath: indexPath) as! CustomTableCell
    let strbookdetail : NSString=arrDict[indexPath.row] .valueForKey("booking_detail") as! NSString
    let strdrop : NSString=arrDict[indexPath.row] .valueForKey("drop_address") as! NSString
    cell.Bookdetail.text=strbookdetail as String
    cell.Dropaddress.text=strdrop as String
    return cell as CustomTableCell

}

//It helps to parse JSON  data to table view.

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    TableView.deselectRowAtIndexPath(indexPath, animated: true)
    let tripcontroller = self.storyboard?.instantiateViewControllerWithIdentifier("UpcomingController") as! Secondcontroller
    navigationController?.pushViewController(tripcontroller, animated: true)

}

When tapping on the cell it helps to move to other view controller SecondController

In my SecondController I have two UILabels. In those labels I want to show data i.e strbookdetail and strdrop

How can I pass a reference between the two view controllers?

Answer 1

It is easy to do using property pass data:

In 2th vc:

var dataFromBeforeVC:[String:String] = [String:String]()

override func viewDidLoad() {
    super.viewDidLoad()


    initData ()

}

func initData()  {

    // set data  strbookdetail and strdrop to labelOne & labelTwo

    labelOne.text = dataFromBeforeVC["strdrop"]
    labelTwo.text = dataFromBeforeVC["strbookdetail"]


}

In 1th vc:

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

    TableView.deselectRowAtIndexPath(indexPath, animated: true)
    let tripcontroller = self.storyboard?.instantiateViewControllerWithIdentifier("UpcomingController") as! Secondcontroller

    let cell:UITableViewCell = tableView.cellForRow(at: indexPath as IndexPath)!

    let strbookdetail : NSString=arrDict[indexPath.row] .valueForKey("booking_detail") as! NSString
    let strdrop : NSString=arrDict[indexPath.row] .valueForKey("drop_address") as! NSString
    tripcontroller.dataFromBeforeVC = [
        "strdrop":strbookdetail,
        "strdrop":strbookdetail
    ]

    self.navigationController?.pushViewController(tripcontroller, animated: true)
}
