Xamarin.ios 绑定问题：在绑定类上调用基方法调用重写方法。导致无限递归

我正在做一个使用Cordova的MonoTouch项目。我为Cordova（）创建了一个绑定

我能够很好地实例化这些类，没有失败。然而，当我试图扩展它们时，我遇到了问题。例如，如果我只是尝试扩展CDVViewController，甚至不重写任何内容，那么当我们看到实例化这个扩展类的代码时，系统会安静地退出，没有错误消息，下面是退出行

The program 'Mono' has exited with code 0 (0x0).
The program '[5600] ***.vshost.exe: Managed (v4.0.30319)' has exited with code -1 (0xffffffff).

这是我试图实例化的类

public class WebViewController : CDVViewController
{
}

这是它后面的装订

[BaseType (typeof (UIViewController))]
interface CDVViewController {
    [Export ("webView")]
    UIWebView WebView { get; set; }

    [Export ("pluginObjects")]
    NSMutableDictionary PluginObjects { get; }

    [Export ("pluginsMap")]
    NSDictionary PluginsMap { get; }

    [Export ("settings")]
    NSDictionary Settings { get; }

    [Export ("whitelist")]
    CDVWhitelist Whitelist { get; }

    [Export ("loadFromString")]
    bool LoadFromString { get; }

    [Export ("useSplashScreen")]
    bool UseSplashScreen { get; set; }

    [Export ("activityView")]
    UIActivityIndicatorView ActivityView { get; }

    [Export ("imageView")]
    UIImageView ImageView { get; }

    [Export ("wwwFolderName")]
    string WwwFolderName { get; set; }

    [Export ("startPage")]
    string StartPage { get; set; }

    [Export ("commandQueue")]
    NSObject CommandQueue { get; set; }

    [Export ("commandDelegate")]
    NSObject CommandDelegate { get; set; }

    [Export ("userAgent")]
    string UserAgent { get; }

    [Export ("printMultitaskingInfo")]
    void PrintMultitaskingInfo ();

    [Export ("createGapView")]
    void CreateGapView ();

    [Export ("newCordovaViewWithFrame:")]
    UIWebView NewCordovaView(RectangleF bounds);

    [Export ("javascriptAlert:")]
    void JavascriptAlert (string text);

    [Export ("appURLScheme")]
    string AppUrlScheme ();

    [Export ("parseInterfaceOrientations:")]
    NSArray ParseInterfaceOrientations (NSArray orientations);

    [Export ("supportsOrientation:")]
    bool SupportsOrientation (UIInterfaceOrientation orientations);

    [Export ("getCommandInstance:")]
    NSObject GetCommandInstance (string pluginName);

    [Export ("registerPlugin:withClassName:")]
    void RegisterPluginWithClassName (CDVPlugin plugin, string className);

    [Export ("URLisAllowed:")]
    bool UrlIsAllowed (NSUrl url);

    [Static] [Export ("getBundlePlist:")]
    NSDictionary GetBundlePlist (string plistName);

    [Static] [Export ("applicationDocumentsDirectory")]
    string ApplicationDocumentsDirectory ();

    // The following methods and properties come from UIWebViewDelegate, but we can't do multiple inheritance
    [Export ("webView:shouldStartLoadWithRequest:navigationType:")]
    bool ShouldStartLoad (UIWebView webView, NSUrlRequest request, UIWebViewNavigationType navigationType);
}

我为其构建绑定的

任何人能提供的任何帮助都将不胜感激

更新#1 这似乎是由分段错误引起的。对于其他经历过这种情况的人，如果你进入Mac并查看日志，你可能会发现同样的情况。您可以打开终端，输入

tail-f/var/log/system.log

，因为这显然是模拟器的日志所在

在我的日志中，我发现了以下内容<代码>***用于编辑应用程序名称

更新#3 为了获得更多信息，我决定在本地WebViewController中重写CDVViewController中的所有方法，然后从每个方法的基等价物返回值，并在该方法上设置断点，并放置一个Console.WriteLine，说明我们输入和退出了每个方法

令我惊讶的是，Update#2中出现许多重复的原因与以下事实有关：当调用

WebViewController.ShouldAutoRotateToInterfaceOrientation

时，我们称基类为

CDVViewController.ShouldAutoRotateToInterfaceOrientation

，这显然会依次调用

WebViewController.ShouldAutoRotateToInterfaceOrientation

，等等

查看我正在使用的Cordova（）版本的源代码，

应该自动旋转指针FaceOrientation:

将调用

supportsOrientation:

，它将从

NSArray

返回

---

我看不出为什么

CDVViewController.shoulldAutorotateTointerFaceOrientation

应该调用

WebViewController.ShouldAutoRotateToInterfaceOrientation

。Xamarin或Cordova社区中有人知道吗？

如果其他人遇到与绑定相关的类似问题，我在Rolf Bjarne Kvinge（）的建议下成功地解决了这个问题

事实证明，我使用的一个标志（没有真正理解它做了什么）应该对此负责。使用

b触摸

生成DLL时，

-e

标志

生成不能子类化的较小类

删除此项可能会解决您的问题，就像它为我所做的一样
