Cell is not selectable embed UItableView inside main View? - ios

Question

I have UITableView embed inside a main UIView. My problem is when I click on a cell to select items, it is not responding to the selection or triggering the segue.
Note: In attributes inspecter
is selection supposed to be set to single selection?
Update Note: the prepareForSegue function is not triggering or print "test".

Answer 1

In this answer I am making the assumption that didSelectRowAtIndexPath is firing.
In your didSelectRowAtIndexPath, you need to fire the segue that you created from the cell to the second view controller:
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
print("selected row", indexPath)
performSegue(with: "segueIdentifier")
}
I'm not sure what version of Swift you are using, so you might need to make some slight changes.

Answer 2

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
//self.performSegue(withIdentifier: "sites", sender: self)
self.performSegue(withIdentifier: "CHANGE-TO-YOUT-SEGUE-ID", sender: self)
}
is the "hello" get printed? if so, call your segue from this point. Don't forget to connect your segue (from the top left square) in the story board as manual segue:

Answer 3

If func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) is not called at all, your problem is that the delegate of your UITableView is not set (or not correctly set). The delegate should be your EditNpFormViewController.
You can easily set the delegate of your UITableView instance by simply Control-dragging from the table to the controller that contains it (inside the Storyboard). The other simple way is by setting
tableView.delegate = self
You can just select the table inside the storyboard and drag the delegate from the right panel's circle to your controller:

Answer 4

If your delegate is set right, check the selection attribute of the cell itself:

Answer 5

If your table view is in editing mode, you need to set tableView.allowsSelectionDuringEditing = true
