Question

我遇到了这个错误，只发生在设备上而不是模拟器上。我正在尝试保存包含字段的用户个人资料：名字，姓氏，电子邮件，性别，出生日期和可选照片（字节[]）。

无论我是否使用照片，都会调用API，然后我立即收到此错误。看起来错误与Rest反序列化有关。

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

我非常感谢对此的任何见解。谢谢！

来自堆栈跟踪的那一行是一个暗示Mono运行时试图在崩溃之前显示（log）的东西。在这种情况下，您应该使用Xcode的管理器来查看控制台日志。会打印一些文字，告诉你出了什么问题。

最常见的情况（6.0.8之前）是缺乏蹦床（类型0,1或2）。考虑到下面的堆栈框架，这更可能是：

请参阅here以获取描述以及如何解决它（但您仍需要阅读控制台以了解需要哪种蹦床类型 - 或者它可能是其他类型的蹦床类型。）

注意：其中一个（刚刚发布的）MonoTouch 6.0.8 主要新功能是，它不需要（对于开发人员）更改此设置（它会自动适应）。希望它的存在很快就会完全被遗忘。

RestSharp / MonoTouch仅在设备上出错
