我们可以在UITableViewCell中添加滚动视图吗？

Question

I have requirement where I have to show some images which are differentiated according to Groups they belong to. I have used a table view to view images listed under groups. User has to scroll horizontally to view more images in a particular group. Can we add a scroll view to tableview row to allow user to scroll list of images horizontally? I searched a bit, some comments say its not allowed in apple's HIG some comments say You can add a UIScrollView to a UITableViewCell and as long as you set the contentSize property of the UIScrollView correctly then the UIScrollView will scroll correctly in the horizontal axis

May I get any confirmation on this ?? Or any alternative approach to achieve horizontal and vertical scrolling for different data without using tableview

Answer 1

Of course you can add scrollView in tableView.

 UIScrollView *scrollView=[[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, 320, 100)];            
 [cell.contentView addSubview:scrollView];

Now you can set properties for scroll view accordingly.

Answer 2

Yes it is definitively possible and reasonable.

Here is an excellent tutorial by Felipe Laso that explains it step by step:

How To Make An Interface With Horizontal Tables Like The Pulse News App: Part 2

BTW, the approach described in that tutorial is way more efficient than adding a UIScrollview to each cell.

Answer 3

Sure, this is possible. A UIScrollView inside a UITableCellView will work fine - the HIG says no, probably because it'll be hard to use. The user would have to accuratley scroll either up/down, or left/right and it might be annoying. Shouldn't take long to knock together a quick test.

I have an app with 2 scrollviews - one that allows horizontal scroll, and then inside that another scrollview which allows vertical scroll. The idea is that the user can flick up/down a page, then also flick left/right across pages.

It's not that nice to use, but it's what my client wanted ;)

To make a UIScrollView only respond to horizontal or vertical scroll is all about setting the correct contentSize. Hope this is some help.
