Accessing data from table cell

Question

I'm creating a form and was wondering if anyone knows how to retrieve a UITextField value from a table cell.

- (IBAction)saveForm:(id)sender { NSLog(@"TextField Value => %@", titleField.text); } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { ... switch(indexPath.section) { case 0: if (row == 0) { cell.selectionStyle = UITableViewCellSelectionStyleNone; CGRect titleFieldFrame = CGRectMake(20.0, 80.0, 280.0, 25.0); UITextField *titleField = [[UITextField alloc] initWithFrame:titleFieldFrame]; [titleField setBorderStyle:UITextBorderStyleRoundedRect]; [titleField setTextColor:[UIColor blackColor]]; [titleField setFont:[UIFont systemFontOfSize:16]]; [titleField setPlaceholder:@"Title"]; [titleField setBackgroundColor:[UIColor whiteColor]]; titleField.keyboardType = UIKeyboardTypeDefault; titleField.returnKeyType = UIReturnKeyDone; [cell addSubview:titleField]; } break; return cell;

}

You could simply create an instance variable and assign titleField to that. Or you could assign a tag with [titleField setTag:123] and then later retrieve it via [yourTableView viewWithTag:123].

It worked. I didn't know about the setTag but I will research more about it and see how else it could be used. Thanks DarkDust.

Give a special tag to the titleField, e.g.

 UITextField *titleField = [[UITextField alloc] initWithFrame:titleFieldFrame]; titleField.tag = 11280492;

and then use -viewWithTag: to get that view.

-(IBAction)saveForm:(id)sender { UITableViewCell* cell = ... UITextField* titleField = [cell viewWithTag:11280492]; NSLog(@"TextField Value => %@", titleField.text); }

Hey KennyTM, I appreciate the help, and you have also helped me see other ways of using Tag. DarkDust answer seemed much simpler and also worked. Thanks.
