【问题描述】：
如果我使用下载CloudKitAtlas的demo，并且不修改storyboard，那么我可以编译并执行应用程序。
但是，如果我对故事板执行任何操作导致设计器在 C# 中生成，我会在我的 Designer.cs 中得到以下内容：
namespace CloudKitAtlas
{
[Register ("TableViewMainMenu")]
partial class TableViewMainMenu
{
[Outlet]
[GeneratedCode ("iOS Designer", "1.0")]
CloudKitAtlas.MainMenuTableViewController dataSource { get; set; }
// ILLEGAL
[Outlet]
[GeneratedCode ("iOS Designer", "1.0")]
CloudKitAtlas.MainMenuTableViewController delegate { get; set; }
void ReleaseDesignerOutlets ()
{
// ILLEGAL
if (dataSource != null) {
dataSource.Dispose ();
dataSource = null;
}
if (delegate != null) {
delegate.Dispose ();
delegate = null;
}
}
}
}
故事板源码是这样的：

【问题讨论】：
-
如果您更改 XML 以使 outlet 标签的属性字段显示“delegate”以外的内容，会发生什么？
-
这里到底什么是非法的？ Storyboard 和 Designer.cs 文件对我来说看起来很正常。
-
@AlexSorokoletov 以下是非法的，因为 Delegate 是保留字。
CloudKitAtlas.MainMenuTableViewController delegate -
我明白了，您在代码中的注释并不能准确说明问题所在。解决方案将按照 Abion47 的建议 - 使用其他名称作为出口。
-
@AlexSorokoletov Outlets 在 Xamarin.IOS 中被抽象化，目前尚不清楚如何使用 Visual Studio 或类似工具来完成此操作。
