title: Handling multiple Xib or fixing collapse and expand button on multiple Xib file
body: <p>Now the situation is illustrated in this image:</p>
  
  <p><img src="https://i.imgur.com/ka0Pnnr.jpg" alt=""></p>
  
  <p>I have an app having multiple Xib files calling in one main Xib and its class. I have added expand and collapse view which works on particular xib expand and collapse subviews as required and reduces/Expands Height too.</p>
  
  <p>This works well for one xib section when all tabs of xib files are collapsed and the second xib won't change its y-coordinates, but I'm having a white space between. I want to fix it.</p>
  
  <p>Note: Every xib contains a class referring to it. The whole app won't use auto-resize.</p>
  
  <p>How can I solve this?</p>
