如何在iOS中显示自定义嵌套列表 [英] How to show custom nested lists in iOS

问题描述

我想在iOS中显示一个列表，该列表本身将包含一个列表. 例如，我想创建一个按日排列的任务列表，其中的日期和任务是动态的，因此外部列表为DAY LIST，内部列表为TASK LIST.也想处理对TASKS的单击. 如何在iOS中实现此功能，尝试使用Table Views但由于要显示嵌套列表而无法实现.总之，我想在iOS中显示列表的列表.

I want to show a list in iOS that itself will contain a list. For example I want to create a day wise task list in which the day and task are dynamic.So outer list is DAY LIST and inner list would be TASK LIST.Also want to handle the click on TASKS. How can I achieve this in iOS, have tried using Table Views but cannot achieve it since I want to show nested list.In short I want to show a list of list in iOS.

        func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {

            //It should be greater than your collectionViewCell's size
            return 300.0
