title: How to set Action for UIButton in UITableViewCell
body: <p>I have <code>XIB</code> file <strong>TimerCell.xib</strong> with <code>UITableViewCell</code>. In other class in <strong>cellForRowAtIndexPath</strong> I initialize this <code>UITableViewCell</code>:</p>
  
  <pre><code>    static NSString *CellIdentifier = @"cellTimer";
      TimerCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
      if (cell == nil) {
          //cell = [[TimerCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
          NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"TimerCell"owner:self options:nil];
          cell = [nib objectAtIndex:0];
  </code></pre>
  
  <p>In my <strong>TimerCell</strong> I have two <code>UILabel</code> and one <code>UIButton</code>. For this button I would like to set <strong>action</strong> to some method. </p>
  
  <p>How can I do that? And how to show in the first <code>UILabel</code> the data from my background countdown timer in real time?</p>
