Typo in Swift sample code

[tommyle]

The swift sample code does not setup the view properly. It should be using the width not the height of the tableview. let headerView: ParallaxHeaderView = ParallaxHeaderView.parallaxHeaderViewWithImage(UIImage(named: "YourImageName"), forSize: CGSizeMake(self.tableview.frame.size.width, 300)) as ParallaxHeaderView
