I\'m having some trouble trying to change the background of a UITableView with groups.
_tableView.backgroundColor = [UIColor colorWithPatternImage:[UIImage i
What I usually do with grouped UITableViews is set the background color to clear, and the set that pattern image to the parents view.
self.parentViewController.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"tableBG.png"]];
self.tableView.backgroundColor = [UIColor clearColor];
