Why Extra Padding on top of ThumbnailView?

I am using Three20's TTThumbViewController. Everything works fine except for a padding on top of the thumbnail table which appears开发者_如何转开发 to be reserved for the navigation header, except that it takes the place right below the header. How can I get rid of this white space?

I dont know why this works for sure, but I faced the same problem and found this solution at google group.

Override updateTableLayout in your TTThumbsViewController

- (void)updateTableLayout 
{ 
    self.tableView.contentInset = UIEdgeInsetsMake(4, 0, 0, 0); 
    self.tableView.scrollIndicatorInsets = UIEdgeInsetsZero; 
}
