Working with text fields in a UITableView

Question

Hi

I am making a search form with a number of free text fields that I would like the user to edit in line on a tableview (and not go to a seperate view for each individual item). So far I have it so when you press on the field, a text input dialog appears, here is the relevant code:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];

        UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 130, 25)];
        label.textAlignment = UITextAlignmentRight;
        label.tag = kLabelTag;
        [cell.contentView addSubview:label];
        [label release];

        UITextField *theTextField = [[UITextField alloc] initWithFrame:CGRectMake(150, 10, 140, 25)];
        theTextField.tag = kTextFieldTag;
        theTextField.delegate = self;
        [cell.contentView addSubview:theTextField];
        [theTextField release];

This has the desired effect of allowing a user to press a row and get an edit dialog, but I have a few problems:

1) You can see I have set the text field's delegate to equal self. The class this is run in implements UITextFieldDelegate yet textFieldShouldEndEditing is not being fired.

2)How can i realisticly persist what the user puts in memory. In other words, is it possible to find out which text field the user has selected currently so i can go [myArray getObjectAtIndex:blah] and edit the actual data.

Thanks

Answer 1

1) Are the other delegate methods being called?

2) You can for example set the tag attribute on each text field to identify them, and use that as an index into the array.
