Answer 1

Make sure you are adding a different textview to each of the different reusable cells. If you have, say, 6 cells visible at any time, then you need 6 different textviews.

It sounds like when you scroll, your textview gets used for another cell.

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    MyTableCell *cell = (MyListTableCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {      
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease];

        cell.textView = [[[UITextView alloc] initWithFrame:/** put appropriate rect here **/] autorelease];
        // create other cell structures you need
    }


    // Set up the cell...
}

When you go to edit the text in the textview, the text scrolls up so that the top of the textview is where the new text will appear when typed. Try swiping down on the textview to reveal the previous info.
