I\'m having some trouble trying to change the background of a UITableView with groups.
_tableView.backgroundColor = [UIColor colorWithPatternImage:[UIImage i
Just want to add to Nirav's answer - it can also be done using the iOS 5 appearance proxy.
[[UITableView appearance] setBackgroundView:nil];
[[UITableView appearance] setBackgroundColor:[UIColor lightGreyColor]];
The advantage is that it is applies globally, so you can group all your UI customisations in one place. However, it will apply to all tableViews (not just grouped style).
