title: How to detect the end of loading of UITableView
body: <p>I want to change the offset of the table when the load is finished and that offset depends on the number of cells loaded on the table. </p>
  
  <p>Is it anyway on the SDK to know when a uitableview loading has finished? I see nothing neither on delegate nor on data source protocols.</p>
  
  <p>I can't use the count of the data sources because of the loading of the visible cells only.</p>
