Question

我在UICollectionviewcell.my中创建一个UIImageview和两个UILables存储在NSArray和formate中的数据是NSDictionary，键和值。但数据未在UICollectionviewCell中显示。这是我的代码请检查我的代码。

//---- ItemviewController ---//
  mensarrayimages = @[ @{ @"description": @"Mens Fashion",
                      @"articles": @[ @{ @"image": @"SlimFit.jpg" },

UITableviewcell - ＆gt; UICollectionviewController - ＆gt; UICollectionviewCell。

Answer 1

This is quite a vague question. However, maybe the UI structure is a little off?

UITableView -> UICollectionViewController -> UICollectionViewCell

That is something I have yet to see someone attempt. From what I can see here, you should backtrack to using a simple UITableView or UICollectionView but not both at the same time. Use either:

UITableViewController -> UITableView -> UITableViewCell

or

UICollectionViewController -> UICollectionView -> UICollectionViewCell

I would suggest going with the first since UITableViews are generally easier to code and maintain

数据未显示在UICollectionviewcell中？
