Swift tableView.reloadData（）是否不调用heightForHeaderInSection？

我有一个表格视图，在各个部分中标题的高度不同。当方向改变时，我想更新标题的高度

但是我注意到调用

tableView.reloadData（）

不会影响heightForHeaderInSection方法

如何在方向更改时更改收割台高度

附言 已设置代理。

头部高度部分：

override func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {

    if(section == 1) { return screenHeight - 300 }
    else { return 0 }

}

override func willRotateToInterfaceOrientation(toInterfaceOrientation: UIInterfaceOrientation, duration: NSTimeInterval) {

    if(toInterfaceOrientation.isLandscape)
    {
        if(wasInPortrait){ screenHeight = bounds.width }
        else { screenHeight = bounds.height }
    }
    else
    {
        if(wasInPortrait){ screenHeight = bounds.height }
        else { screenHeight = bounds.width }
    }

    self.tableView!.reloadData()

}

let bounds = UIScreen.mainScreen().bounds
var screenHeight: CGFloat!
var wasInPortrait = true

override func viewDidLoad() 
{
   super.viewDidLoad()

   screenHeight = bounds.height

   if UIApplication.sharedApplication().statusBarOrientation.isLandscape { wasInPortrait = false }

   dispatch_async(dispatch_get_main_queue()) { self.rateMe() }

}

将旋转接口方向：

override func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {

    if(section == 1) { return screenHeight - 300 }
    else { return 0 }

}

override func willRotateToInterfaceOrientation(toInterfaceOrientation: UIInterfaceOrientation, duration: NSTimeInterval) {

    if(toInterfaceOrientation.isLandscape)
    {
        if(wasInPortrait){ screenHeight = bounds.width }
        else { screenHeight = bounds.height }
    }
    else
    {
        if(wasInPortrait){ screenHeight = bounds.height }
        else { screenHeight = bounds.width }
    }

    self.tableView!.reloadData()

}

let bounds = UIScreen.mainScreen().bounds
var screenHeight: CGFloat!
var wasInPortrait = true

override func viewDidLoad() 
{
   super.viewDidLoad()

   screenHeight = bounds.height

   if UIApplication.sharedApplication().statusBarOrientation.isLandscape { wasInPortrait = false }

   dispatch_async(dispatch_get_main_queue()) { self.rateMe() }

}

ViewDidLoad:

override func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {

    if(section == 1) { return screenHeight - 300 }
    else { return 0 }

}

override func willRotateToInterfaceOrientation(toInterfaceOrientation: UIInterfaceOrientation, duration: NSTimeInterval) {

    if(toInterfaceOrientation.isLandscape)
    {
        if(wasInPortrait){ screenHeight = bounds.width }
        else { screenHeight = bounds.height }
    }
    else
    {
        if(wasInPortrait){ screenHeight = bounds.height }
        else { screenHeight = bounds.width }
    }

    self.tableView!.reloadData()

}

let bounds = UIScreen.mainScreen().bounds
var screenHeight: CGFloat!
var wasInPortrait = true

override func viewDidLoad() 
{
   super.viewDidLoad()

   screenHeight = bounds.height

   if UIApplication.sharedApplication().statusBarOrientation.isLandscape { wasInPortrait = false }

   dispatch_async(dispatch_get_main_queue()) { self.rateMe() }

}

您没有根据方向更改页眉高度，您是根据章节号更改页眉高度我需要特别的第1节根据方向更改页眉高度？感谢更新您的问题，现在更有意义您没有根据方向更改页眉高度，您正在根据节号更改它我需要特别的第1节更改方向更改时的高度？谢谢更新您的问题，现在更有意义了
