Take the 2-minute tour ×  I am working on a project in which at
first web service call we are getting some 20 number of data
which we are loading to table view and once we start scrolling
up for view when it reaches 20 number we need to call service
for next 20 no's, like facebook does.  This we need to do for
each next 20 until data ends and load to tableview from last
data of previous call and we can see all data when we scroll
down for previous data. And need to show "more data loading"
when we scroll up table after 20th cell.  Please Help me !

_offset = 0;  - (void)loadFromServer {     NSString *stringURL =
[NSString stringWithFormat:@"%@
