deselectRowAtIndexPath issue

Question

I have just started working with tableViews, and I have 5 cells in a tableview in a viewController embedded in a navigationController. When a cell is pressed another view is pushed in. My problem is that the cell I press is selected but the selection doesn't go away. I have tried with this code:

- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self.tableView deselectRowAtIndexPath:indexPath animated:NO];

NewViewController *newViewController = [[NewViewController alloc] init];

newViewController.theTitle = [self.tableView cellForRowAtIndexPath:indexPath].textLabel.text;

[self.navigationController pushViewController: newViewController animated:YES];

}

The tableView is initialized in the viewDidLoad method.

Still when I click a cell the new viewController is pushed in but the cell stays selected. What might be the issue here?

Answer 1

You've put your code in the didDeselectRowAtIndexPath - put it in the didSelectRowAtIndexPath. This is an easy mistake to make since didDeselect comes up in code completion before didSelect.

Answer 2

Summary :

• You have tableview that is in a ViewController that is in a NavigationController
• Use touch a cell
• A new ViewController is push on the NavigationController Stack
• User hit back and goes back to the screen where you have a tableView

That is what I understand from your question.
At this moment the cell in your tableView should still be selected in order for the user to have a reminder of the last action he as done, but you also want it to get unselected animated at the point ( the mail application is a good example of this behaviour).

So the best place to deselect the cell in your tableView is in - (void)viewDidAppear:(BOOL)animated method of the UIViewController that have the tableview inside it's view. By doing so you will let the user a chance to see the selection before it gently fade away like in mail.

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
    [self.tableView deselectRowAtIndexPath:[self.tableView indexPathForSelectedRow] animated:animated];
}

You can pass nil as argument of deselectRowAtIndexPath, tableView handles it gracefully.
