title: UITableView: load all cells
body: <p>Is it possible to load all cells of an UITableView when the view is loaded so that they are not loaded when I'm scrolling?
  (I would show a loading screen while doing this)</p>
  
  <p>Please, it's the only way at my project (sorry too complicate to explain why ^^)</p>
  
  <p>EDIT:</p>
  
  <p>Okay let me explain you, what I'm definite doing:</p>
  
  <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView
       cellForRowAtIndexPath:(NSIndexPath *)indexPath
  {
     NSString *cellIdentifier = [NSString stringWithFormat:@"Identifier %i/%i", indexPath.row, indexPath.section];
     CustomTableCell *cell = (CustomTableCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
     NSDictionary *currentReading;
  
     if (cell == nil)
     {
         cell = [[[CustomTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier] autorelease];
  
         UILabel *label;
         UIView *separator;
  
         if(indexPath.row == 0)
         {
             // Here I'm creating the title bar of my "table" for each section
         }
         else
         {
             int iPr = 1;
  
             do
             {
                 currentReading = [listData objectAtIndex:iPr-1];
                 iPr++;
             } while (![[currentReading valueForKey:@"DeviceNo"] isEqualToString:[devicesArr objectAtIndex:indexPath.section]] || 
                        [readingresultsArr containsObject:[currentReading valueForKey:@"ReadingResultId"]]);
  
             [readingresultsArr addObject:[currentReading valueForKey:@"ReadingResultId"]];
             //
             // ...
             //
         }
      }
      return cell;
  }
  </code></pre>
  
  <p>My error happens in the do-while-loop:
  "listData" is an array with multiple dictionaries in it.
  My problem ist that when I’m scrolling my table slowly down, all is fine, but when I’m scrolling quickly to the end of the view and then I’m scrolling to the middle, I get the error that iPr is out of the array’s range. So the problem is, that the last row of the first section has already been added to the "readingresultsArr", but has not been loaded or wants to be loaded again.
  That’s the reason why I want to load all cells at once.</p>
