问iOS的ImSDK里面的TIMFriendshipManager没有了怎么获取用户信息？

#ifndef ImSDK_ImSDK_h

#define ImSDK_ImSDK_h

#import "TIMComm.h"

#import "TIMManager.h"

#import "TIMMessage.h"

#import "TIMConversation.h"

#import "TIMGroupManager.h"

#import "TIMCallback.h"

//#import "TIMFriendshipManager.h"

//#import "IMSdkInt.h"

#endif

没有 TIMFriendshipManager 了
