UITableViewStyleGrouped = The section headers and footers do not float.

UITableViewStylePlain = Any section headers or footers are displayed as inline separators and float when the table view is scrolled

You just change the UITableViewStyle to UITableViewStylePlain

Then to scroll to particular row and section programatically you could use this below UITableViewMethod method.

//Scroll to First row in 2 section
[yourTableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:1]
                     atScrollPosition:UITableViewScrollPositionTop animated:YES];
