title: UICollectionView's cellForItemAtIndexPath not recognizing individual cell frames
body: <p>I am having an issue adding labels to individual cells in a UICollectionView. Using the code shown bellow, the label is added only to the first cell in the collection and none of the others. However, if I change cell.contentView in the third to last line to collectionView, the labels are all added to the right locations, which means I'm dealing with at least the right frame, but I need the labels to be added to the cells themselves.</p>
  
  <pre><code>- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
      {
      UICollectionViewCell* cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"CalendarItem"
                                                                                                        forIndexPath:indexPath];
      UILabel* dayLabel = [[UILabel alloc] initWithFrame:cell.frame];
      [dayLabel setFont:[UIFont fontWithName:@"Helvetica-Bold" size:15]];
      [dayLabel setBackgroundColor:[UIColor clearColor]];
      [dayLabel setTextAlignment:NSTextAlignmentCenter];
      [dayLabel setText:@"!"];
  
      [cell.contentView addSubview:dayLabel];
      [cell setBackgroundColor:[UIColor whiteColor]];
  
      return cell;
  }
  </code></pre>
  
  <p>I'm doing this all programmatically so here is my initialization code for the collection I'm using:</p>
  
  <pre><code>frame.origin.y = self.view.frame.origin.y + ROW_SIZE;
  frame.size.height = self.view.frame.size.height/2 - 2 * ROW_SIZE;
  UICollectionViewFlowLayout *flow = [[UICollectionViewFlowLayout alloc] init];   
  CGSize size = CGSizeMake(frame.size.width/7 - 2 * CALENDAR_EDGE_SPACING,
                                   frame.size.height/5 - 2 * CALENDAR_EDGE_SPACING);
  [flow setItemSize:size];
  [flow setScrollDirection:UICollectionViewScrollDirectionVertical];
  calendarView = [[UICollectionView alloc] initWithFrame:frame collectionViewLayout:flow];
  
  [calendarView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:@"CalendarItem"];
  </code></pre>
