我有一个为 WEPopover 使用 btouch 绑定(bind)的应用程序。您可以在下面找到适用于设备和模拟器的 SAMPLE 应用程序的绑定(bind):
https://github.com/anujb/monotouch-bindings
我在另一个应用程序中使用相同的 dll，它可以在模拟器上运行，但会导致设备崩溃:

最佳答案
这是一个 known bug在当前稳定版本 (5.0.*) 中。它在最新的测试版 (5.1.1) 中得到修复 - 请记住，虽然它是测试版并且存在已知的回归(例如，如果您的应用程序很大，则可能无法将其上传到设备)。
如果您更改链接器选项(以链接所有程序集)，您可能成功解决该错误
