我在 monotouch 中绑定了第三方（red park sdk）。我通过使用monotouch绑定项目为red park dll创建了包装器，并在简单的应用程序中实现了dll。在分配委托时，应用程序崩溃。这是我分配代表的代码

rsc=new RscMgr();
            RscMgrDelegate del=new MyRedParkDelegate();

            System.Diagnostics.Debug.WriteLine("this"+del);
            rsc.SetDelegate(del);

我遇到的崩溃是

保存RscMgrDelegate在类的成员变量中。

如果垃圾收集器能够收集它（它没有保存在一个一直存在的变量中），那么当它试图调用它时，Objective-C 将会崩溃。这更有可能发生在设备上，因为垃圾收集器运行得更加积极。
