Scrolling issue in nested UITableview in iOS

Question

I'm creating a layout where the data should scroll vertically and each rows data should scroll vertically. To accomplish this I have used UITableView as parent and inside each UITableViewCell , I am adding UITablview for vertical scroll.

The parent UITableView has only two section, each section has child UITableView . The Child tableView has more than 50 rows. I am facing scrolling issue. I want that the child UITableView scrolls only when the respective section reaches to top of the screen. Now the behaviour is it scrolls independentaly.

How we can achieve this?

Answer 1

您必须创建内部UITableView的自定义子类，并根据您的条件覆盖以下方法并返回true / false：

touchesShouldBegin(_:with:in:)

Answer 2

Try by setting following property to the main table view.

self.tableView!.delaysContentTouches = true
self.tableView!.canCancelContentTouches = true

Another option is, Use TableView inside CollectionView
