万能的百度，没有找到这个解决方法，我糅合了这个

在函数

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

里增加了以下代码：

CGSize contentSize = self.clevVideo.contentSize;

if(didAddSperateVerticalLine == NO) {

UIView *verticalLine = [[UIView alloc]initWithFrame:CGRectMake(contentSize.width * 0.5 - 0.5, 0, 1, contentSize.height - 8)];

verticalLine.backgroundColor = [UIColor lightGrayColor];//colorWithRed:225/225.0f green:227/225.0f blue:233/225.0f alpha:1.0];

verticalLine.alpha = 0.35;

[self.clevVideo addSubview:verticalLine];

didAddSperateVerticalLine = YES;

}

UIView *horizontalLine = [[UIView alloc]initWithFrame:CGRectMake(0, (20 + cell.frame.size.height) * indexPath.row , contentSize.width, 1)];//每一个cell的framee是 17.00, 10.00, 160.00, 160.00 ,

NSLog(@"%ld, => %.2f, %.2f, %.2f, %.2f, ", indexPath.row, horizontalLine.frame.origin.x, horizontalLine.frame.origin.y, horizontalLine.frame.size.width, horizontalLine.frame.size.height);

horizontalLine.backgroundColor = [UIColor lightGrayColor];

horizontalLine.alpha = 0.35;

[self.clevVideo addSubview:horizontalLine];

return cell;

}

效果如下：
