Objective c 调整CollectionView高度后,集合视图单元格不显示
我面临UICollectionView单元格大小问题。我使用两个集合视图和一个表格视图1:-主集合视图,用于刷卡,一次仅显示一个单元格2:-在主集合视图内,我使用表格视图,现在在表格视图内,我使用集合视图,一次显示6个单元格 现在整个过程是我使用一个布局,它是可滑动的,在一个页面上显示6个项目,以此类推 问题是,当我将主单元格高度设置为200时,collectionview单元格内的显示结果与预期不符。 外部集合视图类Objective c 调整CollectionView高度后,集合视图单元格不显示,objective-c,swift3,uicollectionview,Objective C,Swift3,Uicollectionview,我面临UICollectionView单元格大小问题。我使用两个集合视图和一个表格视图1:-主集合视图,用于刷卡,一次仅显示一个单元格2:-在主集合视图内,我使用表格视图,现在在表格视图内,我使用集合视图,一次显示6个单元格 现在整个过程是我使用一个布局,它是可滑动的,在一个页面上显示6个项目,以此类推 问题是,当我将主单元格高度设置为200时,collectionview单元格内的显示结果与预期不符。 外部集合视图类 import UIKit class ViewController: UI
