title: how to add change event on two different UIpickerView in same storyBoard
body: <p>i have two different UIpickerView's in same storyboard, and i want to add change event on them and bind different actions with them.</p>
  
  <p>i used below code, it adds event to both the UIpickerView but i want to add to different actions on both of them. But in this case, as both are triggering same action thats why doing the same work.</p>
  
  <pre><code>- (void)pickerView:_picker didSelectRow:(NSInteger)row inComponent:(NSInteger)component{
  
  }
  </code></pre>
