我对 Monotouch 很陌生,遇到了一个令我困惑的错误。我为滑动样式视图( https://github.com/edgecase/ECSlidingViewController )绑定了一个objective-c库,并且在使用该库期间执行本机代码时一直在获取SIGSEV(具体来说,它发生了当我尝试从滑动控制器显示底部视图时)。

used by your application.

奇怪的是,它只发生在我在 iOS 模拟器中运行应用程序时。在设备上,一切似乎都运行良好。

有人知道发生了什么吗?

将 Objective-C 块编组到ECSlidingViewController.AnchorTopView.

我们目前不支持编组 Objective-C 块(一开始不是来自托管委托),您最终会遇到像这样的崩溃。

如果您不需要覆盖 ECSlidingViewController.AnchorTopView,您可以在绑定中将块键入为 IntPtr,所以它会是这样的(请注意,我只是在猜测您是如何进行绑定的):

interface ECSlidingViewController {
    void AnchorTopView (ECSide first, ECAnimations second, IntPtr block);
}

如果您对这里感兴趣,有人会遇到类似的问题(并且这个论坛帖子包含更多解释)。

“Got a SIGSEGV while execution native code”可能表示在应用程序执行时未找到分配给 InterfaceBuilder 中 UI 元素的某些操作。验证所有与您的 UIElement(UIButton、GesturesRecognizer 等)连接的 IBAction。清除它并重新分配以更正 .h 文件中的 IBAction。特别注意重复视图。

IBAction 与 Interface Builder 连接
