title: Detecting the bottom "bounce" of UITableView
body: <p>I have a table view that performs an animation when the user scrolls down on a UITableView (push thumb up) and a different animation when the user scrolls up (Push thumb down) on a UITableView. </p>
  
  <p>The problem is when the user reaches the bottom of a UITableView and it bounces, the table registers an upward and then downward movement, thus performing the animation when it should not. </p>
  
  <p>This same exact behavior happens when scrolling to the top; however, I am able to detect it like so:</p>
  
  <pre><code>- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView {
  
      self.lastContentOffset = scrollView.contentOffset;
  
  }
  
  
  -(void) scrollViewDidScroll:(UIScrollView *)scrollView {
  
      // Check if we are at the top of the table
      // This will stop animation when tableview bounces
  
      if(self.tableView.contentOffset.y &lt; 0){
          // Dont animate, top of tableview bounce
  
  
      } else {
  
          CGPoint currentOffset = scrollView.contentOffset;
  
          if (currentOffset.y &gt; self.lastContentOffset.y) {
  
              // Downward animation
              [self animate:@"Down"];
  
          } else {
  
              // Upward
              [self animate:@"Up"];
  
          }
  
          self.lastContentOffset = currentOffset;
  
      }
  
  }
  </code></pre>
  
  <p>This works perfectly, but for the life of me I cannot figure out an if condition to detect the bottom as well. I am sure it is simple and I just cant figure it out. </p>
