Ios UITableHeaderView自动布局中的UILabel不适用于iPhone 6

我在TableHeaderView中使用UILabel的自动布局。UILabel的高度不是固定的，可能是单行或多行。我在ViewController中对此进行编码：

    override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    if let headerView = tableView.tableHeaderView {
        let height = headerView.systemLayoutSizeFittingSize(UILayoutFittingCompressedSize).height
        var headerFrame = headerView.frame

        if height != headerFrame.size.height {
            headerFrame.size.height = height
            headerView.frame = headerFrame
            tableView.tableHeaderView = headerView
        }
    }
}

它在iPhone5上运行得非常好。但是，在iPhone6上，当UILabel是单行时，它就会消失

这里是错误日志

    Probably at least one of the constraints in the following list is one you don't want. 
    Try this: 
        (1) look at each constraint and try to figure out which you don't expect; 
        (2) find the code that added the unwanted constraint or constraints and fix it. 
    (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

Will attempt to recover by breaking constraint

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

可能下面列表中至少有一个约束是您不想要的。
试试这个：
（1） 看看每一个约束，试着找出你不期望的；
（2） 找到添加了不需要的约束的代码，然后修复它。
（注意：如果您看到不理解的NSAutoresizingMaskLayoutConstraints，请参阅UIView属性TranslatesAutoResizingMaskToConstraints的文档）

将尝试通过打破约束进行恢复
在UIViewAlertForUnsatifiableConstraints处创建一个符号断点，以便在调试器中捕获该断点。
中列出的UIView上UIConstraintBasedLayoutDebugging类别中的方法也可能会有所帮助。

有人能帮我吗？

Marco Arment有一个关于如何做到这一点的详细说明。

没有什么可看的，只是可能是因为前两行带有NSAutoresizingMaskLayoutConstraint。是否有任何视图使用自动布局而不将TranslatesAutoResizengMaskintoConstraints设置为NO？我在情节提要中为UILabel添加了约束，只是没有大小的固定。我必须在代码中将UILabel TranslatesAutoResizengMaskintoConstraints设置为NO吗？不，这已经解决了，我想你可以用dasdom的答案来解决它。@RickvanderLinde不幸的是，它不起作用。我的问题不是UILabel resize tableHeaderView，请看我问题中的图片。它不起作用。我说，iPhone5很好用，iPhone6不行。请看我问题中的图片。
