title: UIButton to cover a UITableViewCell
body: <p>I'd like one of my table rows to be a button that takes up an entire row of my UITableView. I figured the best way to go about this is to instantiate a UIButton, and give it the same frame size as an instance of UITableViewCell, and add that as a subview to the cell. I'm almost there, but quite a few pixels off to not get that perfect touch to it. Is there a better approach to this, or perhapsps can my placement accuracy be fixed up to get that perfect alignment?</p>
  
  <pre><code>cell = [tv dequeueReusableCellWithIdentifier:CellIdentifier];
  if(cell == nil) {
      cell = [self tableviewCellWithReuseIdentifier:CellIdentifier];
  }
  UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
  [button setFrame:CGRectMake(0.0f, 5.0f, 320.0f, 44.0f)];
  
  [button setTitle:@"Do Stuff" forState:UIControlStateNormal];
  [button addTarget:self action:@selector(doStuff:) forControlEvents:UIControlEventTouchUpInside];
  [cell addSubview:button];
  </code></pre>
