我在https://github.com/ayoung/Newtonsoft.Json尝试了JSON.NET和MonoTouch端口，但收到此序列化错误：
Ran out of trampolines of type 2 in '/private/var/mobile/Applications/A901C3E6-D9AB-44AF-AA13-6B6E44467BAE/StaffRostering.app/mscorlib.dll' (128)

我也试过了RestSharp.Monotouch并得到了类似的错误：

以下是解决方案：
退出2型蹦床
如果您使用大量接口，您可能会在设备上收到此消息。您可以通过修改项目选项“iPhone Build”部分来创建更多类型2蹦床（键入IMT Thunks）。您想为Device构建目标添加额外的参数：
-aot "nimt-trampolines=512"
IMT Thunk蹦床的默认数量是128.尝试增加此数字，直到您有足够的使用接口为止。
我不知道蹦床究竟是什么......
