有个单例里面有些变量，创建了属性给他赋值好像不行
@interface MXManager : NSObject
{
NIMSession *currentSession;
NIMMessage *currentMessges;
NSString *currentMessgesID;
NSString *currentRedpacketFrom;
NSString *currentRedpackageinfo;
NSString *currentContent;
long long hbStyle;
}
- ( id )sharedManager;
- ( void ).cxx_destruct;
