Is it possible to refresh a single UITableViewCell in a UITableView?
Sorry if the question is stupid but instead of using [mytableview reloaddata],how can we reload the data of only specific UITableViewCell.

You want UITableView's reloadRowsAtIndexPaths: withRowAnimation: method. I've linked the documentation for you.
All you need to provide is the index paths to the cell(s) you want to redraw.

Is it possible to create multiple columns in UITableView, as my requirement demand me to do this, If it is possible how i can i resolve this issue.
Thanks in advance.
You may use UICollectionView for that. Or simply build each UITableViewCell with needed labels and elements in cycle with columns count
First thing you need to do is take a look at UITableViewCell Documetation and Read the Content given there. If you read it properly, you'll get the Answer in the form of these Steps :
Create Custom UITableViewCell with UILabel equals to Number of Columns.
Use this UITableViewCell in your UITableView.
Fill each Row of UITableView with your Database Table Rows.

GoodLuck !!!
If you will use CustomCell there will be scrolling issue. So the best way to do this is UICollectionView for ios6. I did it with CustomCell also so if you are working for ios5 I will guide you.

or you can fallow this blog -

Change the height of the cell in tableView:heightForCellAtIndexPath:, change the cell layout in tableView:cellForRowAtIndexPath: and call [[self tableView] reloadData];.

i am using custom cell in uitableview cell.I am giving button on the right of the navigation bar .if user click on the button the delete cell option has to come like default cell delete option...can any one share code ...thanks in advance....
To delete a UITableViewCell, you should remove the data from the Array that populated the tableview. You can remove it using any logic, and the value of the row returned from the touch.
After that, a simple [tableView reloadData]; will do the trick.
Whenever you click the button corresponding the custom cell you should move the data of the next concurrent cells to their previous cell and then call [reloadData]

You will have to make a custom picker view. There is a method that is viewForPickerView:atComponent:row: or something like that. You will need to return your own view and do your own logic to draw a checkmark.
See my answer here for an elaboration of reproducing a checkmark-enabled UIPickerView, like the one Mobile Safari uses for dropdown menus.
