scroll - UITableview keeps old cells after reloadData -

i have view tabbar @ bottom , tableview. when barbuttonitem pressed, array holds data tableview changes.

with nslogs, clear array changing, [nsarray count] displays different values. however, when use [uitableview reloaddata], cells stay same.

if scroll bit , scroll down, whatever went offscreen gets updating. i'm guessing because when goes offscreen dequeued , when comes redrawn new data. there way have redraw everything?

remove line code:
linktableview = [[uitableview alloc] init];

or other initializers uitableview , use code update sections

  [self.tableview beginupdates]; nsmutableindexset* index = [[nsmutableindexset alloc]init]; [index addindex:0]; [self.tableview reloadsections:index withrowanimation:uitableviewrowanimationautomatic]; [self.tableview endupdates];
