ios - online and offline status users in uitableview quickblox -

-

i found tuto explain how offline/online status 1 users purpose status of list of users that's why when tried put 

[qbusers userwithid:usercell.id delegate:self];

in cellforrow many responses webservice don't know how fix that.

to realtime online/offline status of users can use contactlist chat api http://quickblox.com/developers/simplesample-chat_users-ios#contact_list

you should create datasource table, example array of users.

when receive update status of user callback - should update datasource, example this

- (void)chatdidreceivecontactitemactivity:(nsuinteger)userid isonline:(bool)isonline status:(nsstring *)status{      user *user = [self.mydatasource userwithid:userid];      user.online = isonline;       [self.tableview reloaddata]; }

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()
