Uitableview 在Tableview中动态设置行高仅适用于某些单元格

我有一个表视图，其中的行由数组中的数据填充。 通过调用以下函数在viewDidLoad（）中动态设置行高：

func configureTableView() {          
    /*  When you set the rowHeight as UITableViewAutomaticDimension, the table view knows to use the auto layout constraints to determine each cell’s height. This also reuqires a estimetedRowHeoght, an arbitary number */      
    println("Configure Table View called")

   tableView.estimatedRowHeight = 74.0;
   tableView.rowHeight = UITableViewAutomaticDimension;
   tableView.separatorStyle = UITableViewCellSeparatorStyle.None;
}

要填充每行的数据将从Parse加载到数组中。 将数据加载到阵列后，我将调用：

self.tableView.reloadData();

self.configureTableView();

。。。为了重新加载表行数据，然后根据行内填充标签的注释的大小动态重新聚合行高

问题有两个方面：

只有某些行具有动态设置的高度，其他行的行高度似乎是固定的。如果有多行，则无法查看注释

当用户滚动tableview时，刷新的视图所有行都是静态的，没有一行显示为动态设置了高度，只能看到一行注释

欢迎任何意见

我还使用了一个页脚视图，它是用程序和代码创建的，允许fro显示和隐藏键盘，我想这可能与它有关

//viewDidlOad

 /* Setup the keyboard notifications  so does not block textview for adding comments */
        NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyBoardWillShow:", name: UIKeyboardWillShowNotification, object: nil)
        NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyBoardWillHide:", name: UIKeyboardWillHideNotification, object: nil)


        /* Setup the contentInsets fo keyboard  */
        self.tableView.contentInset = UIEdgeInsetsZero
        self.tableView.scrollIndicatorInsets = UIEdgeInsetsZero


        self.edgesForExtendedLayout = UIRectEdge.None
        /* Make sure the content doesn't go below tabbar/navbar */
        self.extendedLayoutIncludesOpaqueBars = true

        self.automaticallyAdjustsScrollViewInsets = false

事先表示歉意，但在此分配设置页脚视图和处理用户输入的代码

 func tableView(tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {


        footerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.bounds.width, height: FOOTERHEIGHT))
        footerView?.backgroundColor = UIColor(red: 243.0/255, green: 243.0/255, blue: 243.0/255, alpha: 1)

尝试使用此代码。override func VIEWDIDISPENCE（animated:Bool）{tableView.reloadData（）}谢谢，我还是这么做的，我也在使用一个以编程方式创建的页脚视图来允许添加注释，可能与此有关，我将在上次使用动态行高时提出问题，我还必须重写另一个tableView函数heightforrowatinexpath。在这种情况下，您只需返回heightThreak，但仍然是相同的。如果您对不同的单元格使用不同的高度，则根据函数参数的indexPath做出决定。
