We can make do with an NSMutableArray object containing strings for each cell. You will have to fill the array with empty strings and use this info to fill the text field. It will be something like,
textView.text = [textViewStringsArr objectAtIndex:indexPath.row];
Since you're doing it programmatically within the view controller, you will have to set the view controller as your text view delegate. You can do
-(void)textViewDidEndEditing:(UITextView *)textView {
UITableViewCell *cell = (UITableViewCell*)textField.superview;
NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
... Since you've the index path, you can map it to an array.
[textViewStringsArr replaceObjectAtIndexPath:indexPath withObject:textView.text];
}
This would be the basic idea. Start with a mutable array of empty strings and modify them every time the text view is updated by replacing the original text with the new text. Hope this helps.
