ContentInsets doesn't work for UITableView

Question

I have a text box in a TableView and when the user selects a switch it appears ( becomes visible) and a keyboard pops up, and when the user turns off the switch the TextBox disappears and keyboard hides. During the time when the keyboard appears and disappears I want to shift the tableView slightly up and then back to original position. Here is the code

-(IBAction)actionSwitch:(id)sender
{
isSearchTerm = [switchSearchTerm isOn];
[self.tableView reloadData];
if(isSearchTerm == YES)
{
    [txtSearchTerm becomeFirstResponder];
    floatBottom = self.tableView.contentInset.bottom;

    self.tableView.contentInset=UIEdgeInsetsMake(0,0,200,0);
    [self.tableView scrollToRowAtIndexPath:[self.tableView indexPathForSelectedRow] atScrollPosition:UITableViewScrollPositionTop animated:YES];
}
else
{
    [txtSearchTerm resignFirstResponder];
    self.tableView.contentInset=UIEdgeInsetsMake(0,0,floatBottom,0);
    [self.tableView scrollToRowAtIndexPath:[self.tableView indexPathForSelectedRow] atScrollPosition:UITableViewScrollPositionBottom animated:YES];
}
}

The else part doesn't bring the tableview back to its original position, please help.

I solved this by setting the extend under top bar property to NO , under view controllers properties in Property inspector by selecting the ViewController.
