Swift looping through array

I have a UITableView that has 100 cells. I want to create an array that will hold index values of that table that I want to disable the table cells if the table row selected matches any of the values in the array.

I have found that the following code works to disable a specific cell that I give it.

UITableViewCellSelectionStyle.none

Any help on this would be greatly appreciated.

This is how I am checking which cell is selected:

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {





            let selectedRow = tableView.indexPathForSelectedRow?.row

            let workoutSelected = selectedRow

            stringPassedTableView = workoutSelected!



            let myVC = storyboard?.instantiateViewController(withIdentifier: "showWorkout") as! WorkoutViewController

            myVC.stringPassed = stringPassedTableView

            navigationController?.pushViewController(myVC, animated: true)





    }

I should also note that I found that I can accomplish this by giving it a value: if(indexPath.row == 2) { UITableViewCellSelectionStyle.none }

So if you need to disable cells in row 0, 5, 13, 67 then you need an array that contains 0, 5, 13, 67?

Don't use an array containing index paths. Add the selected or enabled information to your data model. The benefit is that the Ui will be reliably updated in cellForRow.

Why do you call indexPathForSelectedRow? That's pointless. The method gives you the index path in the indexPath parameter.

You can use the following tableview delegate method to allow selection or not

tableView:willSelectRowAtIndexPath:

Simply check if the cell index is in your disabled cell indexes and if so return nil. Otherwise return the indexpath.

You can see the documentation here:

A much better way that, create an array of your model class which data you are passing into tableView data source.

Add a property into model class like named as "isSelectable" and assign it properly when you are parsing your model class data.

Use this "isSelectable" property, when you will select a row then check this property it is true or false and performs operation accordingly.

Hope you understand !!
