title: How to merge two UITextView in iPhone?
body: <p>I am worked in autocomplete text in textview, so I am using two <code>UITextView</code> the first <code>UITextView</code> (<code>duplicateTextView</code>) is background text like watermark text and the second <code>UITextView</code> (<code>customTextView</code>) is user entering the text. When the user enters multiline text in textview, the <code>customTextView</code> scrolls automatically but the <code>duplicateTextView</code> is not scrolling. So, how can I scroll the <code>duplicateTextView</code> while the multiline text is enters? Is it possible to merge two <code>UITextView</code> together in iPhone?</p>
  
  <p>Here I tried the source code:</p>
  
  <pre><code>duplicateTextView = [[UITextView alloc] initWithFrame:CGRectMake(0, 50, 320, 100)];
  duplicateTextView.delegate = self;
  duplicateTextView.scrollEnabled = YES;
  duplicateTextView.font = [UIFont fontWithName:@"Helvetica" size:14];
  duplicateTextView.textColor = [UIColor lightGrayColor];
  [self.view addSubview:duplicateTextView];
  
  customTextView = [[UITextView alloc] initWithFrame:CGRectMake(0, 0, 320, 100)];
  customTextView.layer.borderWidth = 2.0;
  customTextView.delegate = self;
  customTextView.backgroundColor = [UIColor clearColor];
  customTextView.layer.borderColor = [UIColor blackColor].CGColor;
  customTextView.font = [UIFont fontWithName:@"Helvetica" size:14];
  customTextView.textColor = [UIColor blackColor];
  [duplicateTextView addSubview:customTextView];
  </code></pre>
