Question

I have an app right now that has a table view with multiple cells that were loaded from an array. I delimited the text in a text view to separate the text into components that then were added to an array. From there I set the text label of each cell to each component in the array. So I have something that looks like this…

And I want to be able to select a cell and it highlights the cell, then I want to be able to click one of the buttons on the right. When I click a button it takes the text label of that cell and stores it in an array as a component.

I don’t know how I would go about writing the code for “take the text label of the selected cell and store it as a component.” Is there a way to detect if the cell is selected?

You’ll want to use a NSMutableArray to achieve this because you can add and remove objects from it on the fly:

- (void)viewDidLoad
{
    [super viewDidLoad];
    myMutableArray = [[NSMutableArray alloc] init];
}

- (void)myButtonClicked
{
    NSMutableArray *myMutableArray;
    UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:[self.tableView indexPathForSelectedRow]];
    if ([myMutableArray containsObject:cell.textLabel.text]) {
        [myMutableArray removeObject:cell.textLabel.text];
    }else{
        [myMutableArray addObject:cell.textLabel.text];
    }
}
