title: Table View Scrolling Issue with content offset
body: <p>I am trying to scroll my table view to show my last cell when keyboard is active.
  This is what i am doing in <code>tableView:cellForRowAtIndexPath:</code>...</p>
  
  <pre><code>if (keyboard) {
  
      CGFloat calculatedPosY = 70 * ([Array count]-1);
      MyTable.contentOffset = CGPointMake(0.0, calculatedPosY);
  
  }
  </code></pre>
  
  <p>its working correctly for first time but for second time when its reloading table its not scrolling. For third time its again scrolling and showing last cell of table. Alternatively the code is working and the log gives the same content offset (0,280).</p>
  
  <p>Please tell were I am doing wrong.
  Thanks in advance.</p>
