Answer 1

The problem is that you've got IBOutlets that link to prototype cells. Note that prototype cells are just that: prototypes. So you can have multiple instances of each. Therefore Xcode won't know which instance to link the IBOutlet variable to.

You'll have to wait until the cells are instantiated inside cellForRowAtIndexPath to assign the properties

Answer 2

This may help. The key is that you need to set the Tag values in IB for your Storyboard outlets.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

  UITableViewCell *cell = [[UITableViewCell alloc] init];

  cell = [tableView dequeueReusableCellWithIdentifier:@"LogRecordCell"];

  cmiJournal = (CMIJournal *)[fetchedResultsController objectAtIndexPath:indexPath];

  UILabel *useJName = (UILabel *)[cell.contentView viewWithTag:101];
  UILabel *useJTime = (UILabel *)[cell.contentView viewWithTag:102];
  UITextView *useJRecord = (UITextView *)[cell.contentView viewWithTag:103];

  useJName.text = cmiJournal.cmiJournalName;
  useJTime.text = fnlDate;
  useJRecord.text = cmiJournal.cmiJournalRecord;

  return cell;
}
