UICollectionviewCell不在ios 7上更新

Question

您好，我正在从事UICollectionViewCell，在我的collectionview中总共有9个单元格，我想在索引'1'的CollectioviewCell上添加徽章图标。每次使用buttion操作更新带有int值的徽章。 问题是我第一次通过UIButton的行动更新徽章VALU，第一次它的工作好，但我更新了徽章第二次显示了在8细胞，再次更新徽章显示了7细胞，在1号位再次更新显示， my Sample Code is here

什么是错在我的代码，请帮助我.. 在此先感谢

试试这个，我认为这是重复使用的细胞，例如每次重置电池更换吹制法

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath 
{ 

    cell = (HomeCollectionView *) [collectionView_ dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath]; 
    cell.backgroundColor = [UIColor lightGrayColor]; 
    cell.CellImageView.image = [UIImage imageNamed:@"Mahasivaratri-Lord-Shiva.jpg"]; 
    cell.title.text= [NSString stringWithFormat:@"%d",indexPath.row]; 
    cell.badge.tag = indexPath.row; 
    //add this 2 lines 
    cell.badge.text = @""; //reset the text 
    cell.badge.frame = CGRectMake(cell.bounds.size.width-25,5,25,25); //and also frame of badge 
    // 
    if (indexPath.row == 1) 
    { 
      NSLog(@"unreadMessages---- Menu --- %d and Indexpath-- %ld",UnreadMessages,(long)indexPath.row); 
      NSInteger width = [self autoBadgeSizeWithString:[NSString stringWithFormat:@"%d",UnreadMessages]]; 
      cell.badge.frame = CGRectMake(cell.frame.size.width-35, -10,width, 25); 
      cell.badge.text = [NSString stringWithFormat:@"%d",UnreadMessages]; 
      NSLog(@"cell frame --- %@",cell.badge); 
    } 
    else 
    { 
     //other code 
    } 
    return cell; 
}
