【问题描述】：

您好，我想在您单击一行 uitableview 时加载一个 UIView。 我做了这个链接： ViewController Segue Xamarin 但是在打印中出现以下错误，Man.storyboard 也有模拟器。 下面是具有 uitableview 的视图代码以及 UITableViewSource 的代码。 如果有人可以提供帮助，我将不胜感激。

partial class ListaWodsFemininosViewController : BaseController2

    public ListaWodsFemininosViewController (IntPtr handle) : base (handle)
    
    

    public override void ViewDidLoad ()
    
        base.ViewDidLoad ();

【问题讨论】：

我没有看到您遇到的错误。你能用它更新帖子吗？错误发生在哪一行？如果需要帮助查找行，请使用异常断点。

请不要发布错误的屏幕截图。搜索引擎无法索引屏幕截图。花点时间复制帖子中的错误并对其进行格式化，使其易于阅读。

我按照上图进行了调整。在以下标识符中。但它仍然没有工作。该行给出的问题是： detLocal.PerformSegue ("detail", detLocal);方法：public override void RowSelected(UITableView tableView, NSIndexPath indexPath) 错误是：

【参考方案1】：

认为你需要像这样给你的 segue 一个 ID：

刚刚注意到您使用的是 Xamarin ios 设计器，所以这里也是该设计器的屏幕截图；)
