in iOS 6
[uitableview setBackgroundColor:] not setting the color when table style is UITableViewStyleGrouped
instead the default striped background is seen.
How should we set the background of the table if the style is UITableViewStyleGrouped
self.view.backgroundColor = TTSTYLEVAR(mainPageBackground);
self.tableView.separatorColor = TTSTYLEVAR(mainPageBackground);
self.tableView.backgroundView = nil;
Fixed it for me. You'll have to be careful of what other impacts this might have though.
