Question

我添加了ParallaxHeaderView文件夹但是我收到一条错误消息，说它未声明。

    let headerView: ParallaxHeaderView = ParallaxHeaderView.parallaxHeaderViewWithImage(headerImage, forSize: CGSizeMake(self.view.frame.size.width, 200.0)) as! ParallaxHeaderView

    // Tap Gesture to return to previous view
    headerView.userInteractionEnabled = true
    let tapGesture = UITapGestureRecognizer(target: self, action: "headerTapped")
    headerView.addGestureRecognizer(tapGesture)

    // Label settings
    headerView.headerTitleLabel.font = UIFont(name: "HelveticaNeue-Medium", size: CGFloat(32.0))
    headerView.headerTitleLabel.text = "Shreyas Papinwar"
    headerView.headerTitleLabel.frame.origin.y -= 60.0

    self.tableView.tableHeaderView = headerView

    tableView.dataSource = self
    tableView.delegate = self
}

如果您想在headerViews添加tableView？您需要几种UITableViewDelegate方法。

tableView:viewForHeaderInSection: tableView:heightForHeaderInSection

您可以使用XIB文件创建自定义headerView。 XIB文件允许您超过默认值。

使用未声明的类型“ParallaxHeaderView”
