通过打开生成的老协议实现文件，发现里面有很多IO读写函数的实现以及setter函数的实现，随便举个例子：
- (ApnsYTVoice*) SetFromuuid:(uint32_t) value {
self.hasFromuuid = YES;
self.fromuuid = value;
return self;
}
- (ApnsYTVoice*) SetFrominfo:(Account*) value {
self.hasFrominfo = YES;
self.frominfo = value;
return self;
}
- (ApnsYTVoice*) SetMsgId:(uint64_t) value {
self.hasMsgId = YES;
self.msgId = value;
return self;
}
- (ApnsYTVoice*) SetVoiceType:(int32_t) value {
}
