Midhun MP has your answer and better code style. I would strongly advice replacing all those nested else-ifs with a switch-statement as, well you don't really want else-ifs if you can avoid them...

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
       NSInteger count = 0;
       switch (changeData.selectedSegmentIndex) 
            {
           case 0:
               count = self.tweets.count;
               break;
           case 1:
               count = self.tweets1.count;
               break;
           case 2:
               count = self.tweets2.count;
               break;
           default:
               break;
            }
    return count;
}
