Question

My iOS app is current transferring control to a detail view when an item in a UITableView is selected. This ia a quiz program, and I’d like to change the app so that it just redisplays the same table view with the correct answer highlighted when a row is selected. What’s a good approach for doing this?

Answer 1

Is not clear to me if you know why the detail view is appearing. So I’ll explain just in case. If you are giving control to a detail view is because somewhere in your code you are pushing that detail view. It depends on what kind of UITableViewCell you are using. If you are using one of the defaults styles, your detail view is probably been pushed in either:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

or

- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath

If you are using a custom cell, then you need to look for the method in charge of pushing
that detail view.

I think a good approach would be to:

1. Remove that pushing wherever it is.
2. Not to use an `UITableViewCellAccessoryType, if you are using one.

3. Do something similar to the following on your tableView:didSelectRowAtIndexPath:

   • Find the row for the right answer in your model array, according to tapped cell.
   • Use that row number to generate an NSIndexPath.
   • Use that NSIndexPath to find the correct cell with cellForRowAtIndexPath:
   • Call setSelected:animated: on that cell to highlight it.

NOTE: If your quiz has more answers than the amount of UITableViewCells that fit in the screen you should scroll your UITableView to the right answer for better UX.
