Question

I have a bunch of custom UITableViewCells with a label and textbox. I have the textbox disabled but I want to make it so when the user taps the Edit button it will make the textboxes editable. How can I do this so that ALL the UITextFields in the UITableView become enabled?

I have

- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
    [super setEditing:editing animated:animated];
    [self.navigationItem setHidesBackButton:editing animated:YES];

    if (editing) {

    }
}

but cannot add the textbox enable in there since I don’t have access to all the textfields. Would I need to add code to grab all the cells and loop through them and enable the textfields?

I would do this by setting a isEditing BOOL on your UITableViewDelegate in the setEditing:animated: method and just updating visible cells when the value is changed.

NSArray *visibleCells = [myTable visibleCells];
for (MyTableViewCell *cell in visibleCells)
    cell.textField.enabled = isEditing;

Then, using your UITableViewDelegate again, update new cells as they appear in tableView:willDisplayCell:forRowAtIndexPath:

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
    cell.textField.enabled = isEditing;
}
