UIScrollView 中的行选择 UITableView 问题 [英] Issue with row selection UITableView inside UIScrollView

问题描述

我有一个具有以下布局的视图控制器:

I have a view controller with following layout:

• 容器视图
  • UIScrollView
    • UITableView 作为 UIScrollView
    的子视图
    • Container View
      • UIScrollView
        • UITableView as a sub view of a UIScrollView

        我有另一个 UITableViewController 在其中我有几行和当行被选中时的一些方法.现在我想在 UIScrollView 中显示这个 UITableview.所以我将 UITableView 添加为 UIScrollView 的子视图.表格在滚动视图中显示得很好，但是当我在滚动视图中点击以选择表格的行时，行会被突出显示，但在选择行时不会调用该方法..

        I have another UITableViewController in which I have a few rows and some methods when the row gets selected. Now I want to display this UITableview inside the UIScrollView. So I add the UITableView as a subview of UIScrollView. The table is displayed in the scroll view just fine, but when I tap in the scroll view to select the table's row, then row is being highlighted but the method is not getting called when the row is selected..

            PBDashboardPickupTable *dashtable = [[PBDashboardPickupTable alloc]initWithNibName:@"PBDashboardPickupTable" bundle:nil];
            [self.scrollView addSubview:dashtable.tableView];
        

        我还从界面生成器将滚动视图的 delayContentTouches 设置为 YES 并将 cancelContentTouch 设置为 NO.另外 userInteractionEnabled 设置为 YES... 那么为什么当我点击 table view 的行时没有调用该方法?

        Also I have set scroll view's delayContentTouches to YES and cancelContentTouch to NO from Interface Builder. Also userInteractionEnabled is set to YES... then why is the method not getting called when I tap the table view's row?

        推荐答案

        Apple 在文档中特别警告避免将 UITableView 放在 UIScrollView 中:

        Apple specifically warns in the documentation to avoid putting a UITableView inside of a UIScrollView:

        重要:您不应在 UIScrollView 对象中嵌入 UIWebView 或 UITableView 对象.如果这样做，可能会导致意外行为，因为这两个对象的触摸事件可能会混淆并错误处理.

        Important: You should not embed UIWebView or UITableView objects in UIScrollView objects. If you do so, unexpected behavior can result because touch events for the two objects can be mixed up and wrongly handled.

        由于 UITableView 继承自 UIScrollView，我建议您添加您需要的任何其他视图作为 tableHeaderView、tableFooterView，或作为表格中的自定义单元格.

        Since UITableView inherits from UIScrollView, I would suggest you add any additional views you need as a tableHeaderView, tableFooterView, or as custom cells in the table.
