如何使"myProc =对象的过程"弃用？

Question

我在Delphi Tokyo第 2版下,我有这个声明:

type 
  FIRMessagingConnectCompletion = procedure of object;

我会将其标记为已弃用.我试着这样:

type
  FIRMessagingConnectCompletion = procedure of object deprecated 'Please listen for the FIRMessagingConnectionStateChangedNotification NSNotification instead.';

但没有错误的工作"E1030 Invalid compiler directive: 'DEPRECATED'".我错过了什么？

Answer 1

似乎编译器不允许这样做.但有一个解决方法:

type
    TProc = procedure of object;
    TProc1 = TProc deprecated 'test';

更新:
正如指出的那样,这个变种会更好

type
    __InternalFakeProcType__ = procedure of object;
    TProc = __InternalFakeProcType__ deprecated 'test';
