what is the maximum limitation of view tag on an UITableViewCell
<p>I put a DragView (subclass of UIView) on a UITableViewCell with tag (row+20000)</p>

<pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView 
     cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{   

   NSInteger row=[indexPath row];
   NSInteger section=[indexPath section];
   static NSString *SimpleTableIdentifier1 = @"CellTableIdentifier";
   UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier1 ];
   if  (cell == nil) {
      cell=[[[UITableViewCell alloc] initWithFrame:CGRectZero 
      CGRect dragRect =CGRectMake(12.0f,6.0f,24.0f,24.0f);
      DragView *dragger =[[DragView alloc]  initWithFrame:dragRect];
      [dragger setTag: row+20000 ];

   }
   DragView *newDragger=(DragView*)[cell viewWithTag: row+20000 ];//error

   //......
   return cell;
}
</code></pre>

<p>But when I try to use the codes (line marks with 'error') to access the DragView, debugger shows that newDragger returns 0x0 which means no object.</p>

<p>I do not know where is wrong. I just guess there may be the reason of the amount limitation of maximium tag )</p>

<p>Welcome any comment.</p>

<p>Thanks</p>
