Get key of array with indexPath.row

Question

I have a table, when I select a row I execute this command:

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


     InfoClienteViewController *infoViewController = [[InfoClienteViewController alloc] init];
     [self.navigationController pushViewController:infoViewController animated:YES];

     [infoViewController setIdt:idt[indexPath.row]];


    NSLog(@"You Select -> %zd",idt[indexPath.row]);

}

In my array (idt) I have this values:

[0] -> 2
[1] -> 3
[2] -> 4

So, when I click in the first row on my table (Now the indexPath.row is [0] ), the NSLog was to show the number 2, but return the number 4451524096, why? and how can I solve it?

Arrays can't hold plain numbers (primitive data types like int, float, NSInteger, ...), they can only hold objects. So, when you log idt[indexPath.row] as a plain number you get gibberish.

Your log should be:

NSLog(@"You Select -> %@", idt[indexPath.row]);

to properly log the object.

If your array contains int or integer value then you need to access like this below. But make sure that your array contains all the int values.

//For int data types access it like this

NSLog(@"You Select -> %d", idt[indexPath.row].intValue);

//For integer data types access it like this

NSLog(@"You Select -> %ld", idt[indexPath.row].integerValue);
