Hello,
I am using UITableView in my application. I am using the cellForRowAtIndexPath method of the UITableView control.
My question is that why this method cellForRowAtIndexPath is called whenever I scroll the table.

A:
Only the visible cells are requested. If you scroll the table, it will generate the new ones that come into view...

Thanks, but if I want to generate all the cells at once for the table?

What do you need that for? Existing approach (and reusing cells) is a great optimization really.

If you want to build your table information once, then I suggest you build a data structure to hold the information you need, then look it up when the table cell comes into view. Put it in an NSDictionary, or whatever...
