Question

My for statement seems to be returning more than it should be, and causing an error. Here is the code…

for (BookCustomCell *bcc in [self.tableView subviews])
{
    if (bcc.rowIDTag == [bookID intValue])
    {
        //Do something here.
    }
}

As I step through this everything seems to be fine. It goes through the For statement four times, and each time bcc.rowIDTag exists and has a value. It then goes through it a fifth time. bcc.rowIDTag does not exist and as a result it crashes (SIGABRT).

1. Why would it be going through a fifth time?
2. Conceptually, what am I missing? (The way I understand things it finds all the
   BookCustomCells in the tableView subviews and then iterates through each of them. Is that correct?)
3. Is there a better way to accomplish my goal? (I have a tableview with multiple rows. Each
   row has multiple buttons which are in a custom cell. When I click a button I need to act upon all of the other buttons within that one row/cell.)

(None of this programming stuff is coming easy for me, but I’m bound and determined to learn it. Thanks for your help.)

Answer 1

Your code is wrong, UITableView contains some subviews that are not UITableViewCell‘s, that’s why you’re getting SIGABRT crashes.

for (BookCustomCell *bcc in [self.tableView visibleCells])
{
    if (bcc.rowIDTag == [bookID intValue])
    {
        //Do something here.
    }
}

This should do the trick.
