Answer 1

You can populate the UIScrollView using something like this:

// NSArray *strings;
// UIScrollView *scrollView;
// NSMutableArray *textFields;

self.textFields = [NSMutableArray array];

const CGFloat width = 320;
const CGFloat height = 31;
const CGFloat margin = 0;
CGFloat y = 0;

for(NSString *string in strings) {
    UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(0, y, width, height)];
    textField.delegate = self;
    textField.text = string;

    [scrollView addSubview:textField];
    [textFields addObject:textField];
    [textField release];

    y += height + margin;
}

scrollView.contentSize = CGSizeMake(width, y - margin);

and handle changing the strings in the UITextFieldDelegate methods.
