How to overcome of tapping a row in a table - ios

Question

When I am tapping a row in a table it doesn't show the next screen, but when i tapped for another row it show the previous tapped row's details.
How to solve this problem?
class AllListsViewController: UITableViewController {
var lists: [Checklist]
required init(coder aDecoder: NSCoder)
{
lists = [Checklist]()
super.init(coder: aDecoder)
var list = Checklist(name: " Birthdays")
lists.append(list)
list = Checklist( name: "Groceries")
lists.append(list)
list = Checklist(name: "Cool Apps")
lists.append(list)
list = Checklist(name: "To Do")
lists.append(list)
}
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
override func tableView(tableView: UITableView, didDeselectRowAtIndexPath indexPath: NSIndexPath) {
let checklist = lists[indexPath.row]
performSegueWithIdentifier("ShowChecklist", sender: checklist)
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return lists.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
let cellIdentifier = "cell"
var cell: UITableViewCell! = tableView.dequeueReusableCellWithIdentifier(cellIdentifier)
if cell == nil
{
cell = UITableViewCell(style: .Default, reuseIdentifier: cellIdentifier)
}
let checklist = lists[indexPath.row]
cell.textLabel!.text = checklist.name
cell.accessoryType = .DetailDisclosureButton
return cell
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "ShowChecklist"
{
let controller = segue.destinationViewController as! ChecklistViewController
controller.checklist = sender as! Checklist
}
}
}
And this is my didSelectRowAtIndex.
override func tableView (tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath)
{
if let cell = tableView.cellForRowAtIndexPath(indexPath)
{
let item = items[indexPath.row]
item.toggleChecked()
configureCheckmarkForCell(cell, withChecklistItem: item)
}
tableView.deselectRowAtIndexPath(indexPath, animated: true)
saveChecklistItems()
}

Answer 1

You are messing up the usage of the delegate.
You are calling performSegueWithIdentifier in the wrong delegate method, where the row get's deselected.
If you want to perform the segue you should do it in the tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) method.
Currently you are doing it in the tableView (tableView: UITableView, didDeselectRowAtIndexPath indexPath: NSIndexPath) method.
Here is how it should look like, after you swapped your code:
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath)
{
let checklist = lists[indexPath.row]
performSegueWithIdentifier("ShowChecklist", sender: checklist)
}
