EMVideoMessageBody *body = [[EMVideoMessageBody alloc] initWithLocalPath:@"videoPath" displayName:@"video.mp4"]; NSString *from = [[EMClient sharedClient] currentUsername];   // 生成message EMMessage *message = [[EMMessage alloc] initWithConversationID:@"6001" from:from to:@"6001" body:body ext:messageExt]; message.chatType = EMChatTypeChat;// 设置为单聊消息 //message.chatType = EMChatTypeGroupChat;// 设置为群聊消息 //message.chatType = EMChatTypeChatRoom;// 设置为聊天室消息
